Spotting a 'too good to be true' - what's wrong with this tennis bracelet?

[JB14]

Good morning,

Apologies if this is in the wrong sub-forum, I thought perhaps the diamond experts here would be well versed on this.

I have been looking at tennis bracelets for my wife, having no experience buying jewelry. I had resolved perhaps to 3tcw of lab diamonds, in white gold or maybe even just silver.

I have however recently spotted a business registered in Hatton Garden selling seemingly very low priced real diamond bracelets - both on ebay and online, who have thousands of positive reviews and almost 6000 sales on ebay (all of diamonds). In the spirit of general scepticism I'm trying to understand if they're too good to be true, or just sold at very low margin, or just horribly cheap and nasty and not worth buying even if they are authentic.

I'd buy via ebay so would get the 'GIA authentication' but perhaps there are loopholes? Anyway, the description and images are below. I'd be grateful for thoughts on authenticity/where corners have been cut/quality of the design and fabrication etc.

This is for sale at just over £800, or about $1100.

9kt gold per gram would be about 3.3gbp per gram, and a tennis bracelet would need to be about 8-10 grams at the very least, I would say. So let's say about 30gbp worth of gold in the bracelet. This actually makes me feel like this might be not an outright scam lol but its not going to be the kind of quality they are claiming imo.

I think 800gbp is the kind of price you can expect from this bracelet if you were to buy it in India. I did the math and I think I could get that kind of ballpark here with reasonable but not amazing quality diamonds. It might even be a bit more expensive here tbh.

I refuse to believe this bracelet was made in the UK. The margins won't support it.

This is likely made in an Indian or Chinese factory somewhere and resold by this UK brand. I would expect the craftsmanship to be pretty poor and the diamonds to be relatively included (if they're just claiming SI, that's a pretty good indication it'll be like I1 which at a size of 4-5pts per diamond, will have a significant impact on sparkle).

However, if there's free shipping and returns, I think you don't lose anything by ordering it and seeing it with your own eyes. You'll be hard pressed to beat the price point and sometimes you can be pleasantly surprised.

If the budget supports going for a higher quality to start with, I would do that. This would very much be a bling on a budget deal imo, because of the market you are in.

That's a comprehensive and very useful reply, thank you.

So it's likely genuine insofar that it's in the ballpark of 9k white gold and 2.5ct worth of diamonds, with the caveat that the diamonds might not be of great quality and the craftsmanship might not be very refined.

If I purchased I likely would do so on ebay, as the value means it goes through the GIA assessment which would at least weed out and complete fabrications in the description, and perhaps get it independently assessed regarding the actual diamonds to check whether the description is accurate.

You mention that 'I did the math and I think I could get that kind of ballpark here with reasonable but not amazing quality diamonds' - are you a jeweller and sell such products? Where is 'here' for you? Finding the next step up in quality is difficult for me, as I struggle to assess it and I'm sure there are plenty of retailers selling exactly the same bracelet just for a higher price!

Given it would just be an occasional bracelet and not a daily wearer, do you see anything in the means of construction that would cause you concern?

Thanks again for your input.

I'm not a jeweller, I just like jewellery I live in India and I get all my jewellery from here. I was trying to estimate what my jeweller would charge me for a tennis bracelet like this. That's how I sanity check prices. He doesn't carry SI stones so I don't know what he would price those at, and I don't think he would make something in 9kt gold - Indians are very particular about gold content and 14kt is probably the lowest you can find here. But I tried to price it out as best as I could knowing his prices and it would be in this ballpark or maybe even a bit more.

That is a bit suspicious to me as far as quality indicators go, because the UK is usually expensive for jewellery, not cheap like India is. That's why I'm confident it wasn't made in the UK.

The picture itself doesn't really look concerning but it's also a render, not a picture of the actual bracelet. If it actually has all the safety clasp etc. and if you give it a once over and make sure it doesn't have any loose prongs, broken links etc. it will hold up from a construction POV. How sparkly and pretty it is is impossible to say. Chances are that the stones won't be great, but they might fit the bill for you. I always say that price is king.

I think it depends on how particular you are. I would assume most people on PS would want jewellery of a higher standard. For me, I think of it as a cost-benefit analysis. I mean, maybe you can get double the sparkle but at 3x the price. Would that be worth it to you? No one can answer that question except for you.

 

[dk168]

I am in the UK and do not believe the bracelet is made here for that price, no way!

I have pieces made with 9K Rhodium WG and even Rhodium plated Sterling Silver in order to cut down on setting cost.

H/I SI quality stones should not be frozen spits, however, cutting could be poor resulting in a dull looking bracelet with not much sparkles.

It is definitely on the cheap side and I too would be concerned it could be too good to be true.

However, if the return policy is solidly good, then I might chance it and get one to see what it is like in real life, buying with a credit card for certain!

Perhaps do a bit more research by looking up the company via Company House to check their filings to see if they are financially sound.

Good luck!

[oldminer]

The diamonds will not arrive with individual GIA reports on every stone. Possibly, some GIA Graduate has examined the stones, set or before setting, and made a general report on all the stones lumped into one range of quality. That is NOT GIA Certified, but is most often how the terminology is mis-used.

Still, the value may be very good and look okay to you. No one buys a diamond tennis bracelet as some kind of quasi-investment. They do not last forever if worn a lot. A 9kt one may not wear as well as 14kt or 18kt and will also likely tarnish once the rhodium plating wears away. It can be re-plated if you wish.

If you are local to Hatton Garden, then you ought to go and see one in person. If it looks great, buy the one they show you, not one they send out later. That way, you control the deal. They might send you something very different.

I hadn't even noticed that they were renders! Thanks for your input. Yes I appreciate many would look for better quality, and it may be the case that the finished product doesn't meet my modest expectations, but in my mind a tennis bracelet is more tolerant of a 'budget' element than a solitaire etc.

Thanks for your input. They ado appear to be registered with companies house, but I wouldn't say the accounts are reflective of the amount of ebay trade they seem to be doing. They're a member of the National Association of Jewellers but I feel like that probably doesn't mean much.

They do have a direct website but ordering through ebay I expect I'd get better protections, so would likely do that.

To be frank if ebay wasn't an option I'm not sure I'd make the order - the ebay protections plus the GIA 'certification' (whatever that means) makes me feel a little more comfortable.

I would post a link but I only have a couple of posts and don't want to break any rules or be accused of advertising!

It certainly won't be an investment - just to be worn on rare occasion and enjoyed. The GIA certification is an ebay thing. Once you make the purchase the seller sends it directly to ebay's GIA people, who assess it then forward it to you with the certificates as appropriate. If it doesn't meet the GIA standards (however high or low they might be) they return the item to the seller;

I think the limitation is that the GIA diamond verification is only for >0.15 carats for clarity, and >0.2 carats for colour - and all of the diamonds in the bracelet will be smaller than this - so they won't really assess the diamonds.

I think given the detailed specification in the listing, I'll arrange an independent inspection after delivery and if there are any discrepancies in the listing I'll send it back (or get a discount if I actually like it anyway).

Regrettably I can't go to Hatton Garden, so it'd be lucky dip as to what I'd get!

I think I might go ahead - I'll post photos if/when it arrives!

 

[dk168]

I have found the seller on eBay as well as their website.

I have also done some other research and am still not comfortable with the seller.

Perhaps I need to visit their shop in Hatton Garden when I am up in London later this year.

Good luck with your purchase and please provide an update if you can.

The way I see it, it’s priced pretty similarly to if you were to buy a LGD bracelet from Luvansh or something, so while it’s a risk, it’s not a massive risk. Luvansh is selling an LGD 2ct tennis (in 14kt gold, to be fair) for approx $1100 before taxes.

The independent inspection will also cost money btw, unless you have a nice jeweller who will do it for free. They usually won’t unless you have a longstanding relationship. I would definitely have the caratage of the gold checked and make sure it’s actually 8-10 grams of 9kt gold - a pawn shop would do that for you for free I think.

Also - I need to correct a bit of math I did earlier. I said it was 30gbp of gold but I was converting from INR and I did it wrong. It’s more like 300gbp!!! This is the kind of ratio of gold price to labour that I would see in India. I’m so sorry about that. I just was looking at my old message again and thinking there’s something wrong, because I know in India I’d get a similar price but how is that possible… and then I was like oh crap I think I forgot to multiply by 10 - it was 30ish gbp a gram!!

So it’s actually 300gbp of gold in the bracelet, not 30. That’s totally on me and I hope you see this before you order.

Hi, I’m in USA. The prosumer experts are giving you good advice.

My two cents- For your budget, I’d highly recommend considering newly made with lab diamonds, there’s a discussion forum on this. Another way to reduce cost of retail is to buy a preowned, vintage or antique. I’m looking at 2 ctw 14k lab eternities on a well known USA preowned site for $1300 USD for example.

Do you know your wife’s tastes? If this bracelet you are interested in doesn’t work out there might be other options.

 

[dk168]

To be honest, if all their claims can be verified as true and the bracelet is well-made with sparkly natural earth-mined diamonds in the colour and clarity as stated, then they are under-cutting UK jewellers by a massive amount. HUGH!

Even undercuts the bench I use in China!

I suspect the settings are made elsewhere for the stones to be set in UK, however, I could be wrong. The price is suspiciously low for an all UK-made piece IMHO.

[JB14]

Thanks for all of your input.

After your guidance and a bit of research I share the cynicism expressed by everyone - but with a combination of ebay buyer protection, the returns policy that ebay enforces and various reviews saying returns were processed quickly and without issue, I thought what's the worst that can happen?

I have bought a bracelet just shy of 5ct, and was very careful to check the listing for the following explicit descriptors;

- Solid 9k white gold, nickel free
- Total diamond weight of 4.8ct, natural mined diamond.
- Diamond cut round brilliant
- Colour H-I, Clarity SI
- Cut grade 'very good'

Ultimately I'll hopefully get the item, and get it checked by an independent jeweller. If something turns out to be inferior to the description, then there'll be a judgement call as to whether I'll keep it. If the diamonds are inferior quality to the description but it still looks great for example, I'll keep it - it'd still be good value I think.

I'll provide an update when/if it arrives!

IMO the only things to look out for will be the craftsmanship (I wouldn’t care at this price point if it was sloppy, but I would want to make sure it wasn’t going to break apart at a link) and if you like the look of the diamonds when you see them. If yes then it would be worth keeping.

Best of luck!

Just quoted as you specifically asked for an update.

The bracelet arrived today, having first gone to ebay's authentication service, then delivered to me. https://pages.ebay.co.uk/authenticity-guarantee-jewellery/

The bracelet came with a card with a QR code from the GIA, but on scanning it only gives an 'authenticity confirmed' type message, and not a detailed report, so at the moment I can't actually see what/how they've checked it. I've messaged ebay to see if they can provide something (it comes with an GIA authentication reference) - and all I really want to know is if it's solid 9k white gold, and that the diamonds are real. If the GIA aren't checking those things then you'd think the whole thing is fairly pointless...

In terms of the bracelet itself, I think I'm happy with it;

- The build quality looks very good - I can't see any issues whatsoever.
- The sparkle looks good in artificial light, but I wouldn't say there's a lot in natural light. I think however this might be simply the fact that at 5ct total weight the diamonds are quite small, and I'm basing my expectation on the limited experience I have or larger stones in engagement rings etc.
- It's perhaps smaller (diamond size) than I thought, but with 53 diamonds for a total weight of 5ct that's about 0.10ct per diamond, and they're just under 3mm in width so that seems accurate.

Photos attached;

 

[JB14]

The last photo in particular (showing the side profile with the diamond point) makes them look rather yellow - that's somewhat a result of the camera I used to take the picture - they don't look that yellow in reality.

So I think I'm happy - perhaps less sparkle than expected but that might be due to having the wrong expectations. Also I still feel I need someone with a quality machine to check the diamonds are genuine.

it is a good indicator of natural origin.... out of 53 diamonds.. 35% or so should have it.... so sounds like they are legit....

Thank you so much for the update!!

I think the bracelet looks great, honestly! Sparkle is something you have to gauge by eye… if you’re not familiar with how small stones behave you might not have well calibrated expectations. If you really want to check it out and compare, take the bracelet in to a store like Tiffany (or any well reputed store which carries well cut diamonds) and compare it there. Diamonds do best in shaded natural light imo, and direct light (natural or artificial, like spotlighting) makes them go dark. Still from what you said, this is probably the place you compromised the most in terms of colour clarity and cut, simply because it’s the most variable place with the most wriggle room. At that size it’s the colour they say it is, effectively. And no one is assigning stones that small a cut grade. Still if it looks nice to the eye you did good.

I think the build quality surpassed my expectations: the stones look set (and not jammed) into the baskets, the baskets look like they’re joined together securely, the clasps look good. It’s not perfect for eg the underside where the clasp tongue is on one end, but it also doesn’t look problematic.

At the price you paid, you’d come ahead even if they were lab stones, but half of them fluorescing means it’s likely natural. Score!

Enjoy your bracelet!!!

 

[Dreamer_D]

Just to add: there are deals in diamonds but it is on the secondary market, usually buying from private sellers or scrap/pawn sellers who may not specialize in diamonds.

But from a regular retailer? Absolutely get what you pay for. The goal there is paying a fair price for the product, not a “deal” per se.

I forgot to add - check all the prongs to make sure they aren’t lifted, and are actually holding the stone. You can do it in a couple mins with a loupe if you have one. If prongs are lifted they can snag on threads etc and then can be wrenched open, causing you to lose a stone. If you don’t have a loupe just look really carefully or feel with a fingertip.

I’m not sure if the “rattle test” applies also to tennis bracelets but you can vigorously shake the bracelet around and if you hear a rattling sound, that means one or more stones is not securely held in its basket. Again something to check.

ETA - I don’t know where I got half of them fluorescing from, since you said “some”. But point still remains.

ETA2 - I went and looked at the stats they claimed for the diamonds themselves. There’s really no way to tell - they look far yellower in the pic than what I would expect H-I diamonds to be, but you say that’s an effect of the camera. To my eye, at 3mm, an H-I stone is pretty much just white, or maybe off-white. If it is way yellower than that, then either you’re more sensitive to colour than I am or the colour grade is off by a few. That being said when it’s on your wrist I doubt anyone will really be able to tell. The “very good” cut grade and the SI clarity together are probably contributing to your reduced sparkle (if it actually is reduced. I’d do a comparison with a set standard to be sure). Also make sure the bracelet is clean clean clean before testing out its performance! Small diamonds get dirty very quickly and dirty diamonds won’t sparkle as much.

I understand - I did suspect this to be the case, and hopefully it's clear that I started this thread with the intent of finding the catch. So far I expect that the 'catch' is that the diamonds are of a worse colour, cut and clarity than specified (which I suspected before I ordered).

Ultimately I have something in my hand which the GIA have reviewed per the specification, and they agree that it's accurate (notably colour and clarity are not checked on stones of that size for ebay).

So at the moment, I'm reasonably optimistic that at the very least I have a 9ct gold tennis bracelet with some variety of real diamond!

it is a good indicator of natural origin.... out of 53 diamonds.. 35% or so should have it.... so sounds like they are legit....

Yes it's probably about a third. It's very difficult to get a photo of! That's very reassuring thanks.

Thank you so much for the update!!

I think the bracelet looks great, honestly! Sparkle is something you have to gauge by eye… if you’re not familiar with how small stones behave you might not have well calibrated expectations. If you really want to check it out and compare, take the bracelet in to a store like Tiffany (or any well reputed store which carries well cut diamonds) and compare it there. Diamonds do best in shaded natural light imo, and direct light (natural or artificial, like spotlighting) makes them go dark. Still from what you said, this is probably the place you compromised the most in terms of colour clarity and cut, simply because it’s the most variable place with the most wriggle room. At that size it’s the colour they say it is, effectively. And no one is assigning stones that small a cut grade. Still if it looks nice to the eye you did good.

I think the build quality surpassed my expectations: the stones look set (and not jammed) into the baskets, the baskets look like they’re joined together securely, the clasps look good. It’s not perfect for eg the underside where the clasp tongue is on one end, but it also doesn’t look problematic.

At the price you paid, you’d come ahead even if they were lab stones, but half of them fluorescing means it’s likely natural. Score!

Enjoy your bracelet!!!

Thanks - I'll have to find a jeweller with a similiar size bracelet for some means of comparison - I definitely don't have a Tiffany anywhere near me!

Just to add: there are deals in diamonds but it is on the secondary market, usually buying from private sellers or scrap/pawn sellers who may not specialize in diamonds.

But from a regular retailer? Absolutely get what you pay for. The goal there is paying a fair price for the product, not a “deal” per se.

Yes - I suspect I have got what I've paid for in respect of the gold and (worse than specified) diamonds, and have got a 'deal' on likely cheap labour costs from wherever it was made.

I forgot to add - check all the prongs to make sure they aren’t lifted, and are actually holding the stone. You can do it in a couple mins with a loupe if you have one. If prongs are lifted they can snag on threads etc and then can be wrenched open, causing you to lose a stone. If you don’t have a loupe just look really carefully or feel with a fingertip.

I’m not sure if the “rattle test” applies also to tennis bracelets but you can vigorously shake the bracelet around and if you hear a rattling sound, that means one or more stones is not securely held in its basket. Again something to check.

ETA - I don’t know where I got half of them fluorescing from, since you said “some”. But point still remains.

ETA2 - I went and looked at the stats they claimed for the diamonds themselves. There’s really no way to tell - they look far yellower in the pic than what I would expect H-I diamonds to be, but you say that’s an effect of the camera. To my eye, at 3mm, an H-I stone is pretty much just white, or maybe off-white. If it is way yellower than that, then either you’re more sensitive to colour than I am or the colour grade is off by a few. That being said when it’s on your wrist I doubt anyone will really be able to tell. The “very good” cut grade and the SI clarity together are probably contributing to your reduced sparkle (if it actually is reduced. I’d do a comparison with a set standard to be sure). Also make sure the bracelet is clean clean clean before testing out its performance! Small diamonds get dirty very quickly and dirty diamonds won’t sparkle as much.

Thanks again. I can't feel anything rattle, and the settings seem smooth and tight. It's less than half of them fluorescing - it's about 1/3 of them, which reassuringly is about the figure quoted for genuine diamonds.

As for the colour, whilst I do expect them to be worse than specified, the photo's definitely aren't representative. The lighting on the photos is primarily from two warm wall lights and I suspect that's where the yellow glow is coming from. As an example, the label attached in the picture below is actually white - the yellow tinge seems to have effected everything in the photo;



I've spoken to ebay today and asked for actual details of the GIA authentication, as to what they actually checked. If they can clarify that at the very least it's solid 9k gold, and real diamonds, then anything else I can leave to my own judgement.

I understand - I did suspect this to be the case, and hopefully it's clear that I started this thread with the intent of finding the catch. So far I expect that the 'catch' is that the diamonds are of a worse colour, cut and clarity than specified (which I suspected before I ordered).

Ultimately I have something in my hand which the GIA have reviewed per the specification, and they agree that it's accurate (notably colour and clarity are not checked on stones of that size for ebay).

So at the moment, I'm reasonably optimistic that at the very least I have a 9ct gold tennis bracelet with some variety of real diamond!

Honestly, you got a deal imo, enjoy your bracelet!

The GIA does not review or authenticate jewelry. Someone who has taken classes from GIA might, though. There are various studies that one can take at GIA to earn credentials, but that doesn't mean that someone who has these credentials is the GIA.

I hope that makes sense. I'm just not sure it was clear the way you were talking about it.

Edit...just in case it's not clear, the GIA does grade individual diamonds and gemstones.
