Advice on whether I should keep this diamond

Hi all,

I was hoping to get some advice about whether it would be worth exchanging my current diamond.

My partner and I decided to get an engagement ring pretty much on impulse. I wanted something understated and initially we thought we would just go for the cheapest diamond we could find. After a tiny bit of research we ended up getting a .34 carat from Blue Nile, H IF, GIA triple ex. for abut $600 USD. (I was looking in the g-j range, VS2 to IF and although the clarity and colour of what we finally picked were a bit higher than what I thought we'd get, this seemed to be the best of the options we came across in terms of price - which now sort of makes me wonder if the reason for the lower price is because it was a lesser cut than the other options)

The proportions are:
4.49 - 4.51 x 2.81 mm
Depth 62.4 %
Table 54 %
Crown Angle 35.0°
Crown Height 16.0%
Pavilion Angle 40.8°
Pavilion Depth 43.0%
Star Length 55%
Lower Half 80%
Girdle Medium, Faceted, 3.5%
Culet None


I wanted a stone with as good a cut as possible but, at the time, I didn't want to go above $500ish (even though in the end we did go a bit over). We'd had a look on a few other websites (brian gavin, white flash and we looked at a few James Allen true hearts), but for a similar size they were all $100-$200 more expensive and so we took a risk on the blue nile one, even though we only had the GIA certification available and didn't have any scope or any other information on this stone to tell how it performed.

Having received the stone it does look bright and sparkly under particular lighting, however under a lot of indoor lighting it tends to have a lot of patches of gray (usually in the office or indoors at home). And I noticed that when I hold it with a slight tilt, there tends to be a very obvious dark patch in the middle. I have no experience with diamonds and haven't gone around to look at different stones in jewelry stores (since this was completely an impulse purchase and originally we'd planned on not getting any ring at all) so I have no idea how diamonds are usually meant to look and how bright a well performing diamond should look, and under what conditions.

I had thought the diamond was a bit on the deeper end of most recommended proportion ranges I looked at, although it was within most of the limits. But I'm now wondering whether the dark patch in the middle would be because the ring is too deep or due to some problem with the cut? Or whether I should just consider that it is normal and that it would look like this no matter what cut I get?

So right now I am faced with a bit of a dilemma. I don't know whether I should return this stone for something where I would have more information and would confidently know it is a great cut. I don't really know how good the cut is on my current stone apart from what's on the GIA certificate, and from what I have read that is highly variable and not something i'd want to rely on. And I have no idea how to judge the stone's performance visually. I don't know whether the gray patches and occasional dullness I'm seeing is pretty much what you'd expect even from the best cut stone, or whether something with a better cut would end up looking a lot better in even bad lighting. I'm also wondering how much of a noticeable visual difference a better cut would be expected make to my ring in terms of brightness and fire given its size.

I'm not really too fussed about the price or the exact size, although I'd want to keep the it under .5 carats as I think something bigger would just look a bit too oversized for my finger. Originally I wanted to spend as little as possible as we'd initially thought we weren't going to get a ring at all, but having now adjusted to the idea that I'm going to have a ring, which I will hopefully wear forever, I want to feel like I have something that is as good as possible. It doesn't have to be perfect but I want to know that I not settling on something that is going to look noticeably less brilliant than a similar, better cut stone.

I would be grateful for any advice anyone can give me.

I have attached a few pictures.. The quality is not great as all I had was the camera on my phone, but I've tried to make it as focused as possible and indifferent lighting.

Proportions wise, they are smack bang in what we would consider to be the super-ideal cut range of proportions so good work there! I didn't even need to go take a look at HCA to know that it would go under 2. And it does go under 2 (HCA of 1.7). Any chance that you still have the link to the Blue Nile listing? I take it this was a stone which you bought that did not have any 360 degree video available on the listing?

You could have gotten something larger for your budget if you didn't go for the IF clarity and dropped down to an I or J colour. At carat weights of say 0.75cts and under, you would be very hard pressed to see any inclusions in clarity gradings of VVS1 to VS2. Even SI1. Because you're talking about stones that are 5.5mm or so and under in diameter.

But to be honest, depending on the price you paid (especially if it was not much more than your $500 budget, you may have gotten a decent deal).
 
Hi,

Yes, this stone didn't have any images available so it was a bit of a gamble. I really didn't think I minded too much at the time we bought it, but the more I read up about it, the more I'm attracted to the idea of getting a really good and brilliant stone. Unfortunately I don't have the link to the original listing anymore but from memory all it had was the GIA certificate.

We were initially thinking of something around J VS1 at around .3ct, but this one popped up as pretty comparable in price to the many J and I stones of lower clarity, so we eventually decided to go with this one. The exact amount we paid was $594 USD which seemed to be a really good price compared to other stones with similar stats, but now it's making me worry that the reason was because the light performance isn't too great.

I really have no idea how to tell visually whether what I'm seeing is what a decent stone should look like, or if a good cut stone should look noticeably brighter. It does look very nice in good lighting but I'm willing to pay more to make sure I get a great stone that I wont regret in the future. For sentimental reasons, I don't think this is something I'll upgrade in the future. I think once we've finalised the e-ring, I'd want to always keep the same stone. So I'm a bit unsure at this stage if this is the one I should stick with, in case I end up regretting it in the future
 
It's a beautiful stone proportions size. All diamonds will leak light when tilted. Face on it appears symmetrical and well cut. Diamond fire would be more noticeable in a large diamond due to larger virtual facets, but if this is the size you're after then well done! It is slightly deep which can be forgiven with a table of 54. Just remember to keep it clean regularly, oil and wishes that'll create dark patches and dulls diamonds very quickly

Looks really nice, congratulations
 
Looking at your photos, I can make out distinct arrows and arrow heads in some of the pics. That's a very good thing because if it wasn't cut properly, I wouldn't see a distinct arrows pattern. I do think you have gotten yourself quite a bargain. Congrats on the engagement and all the best for the future!
 
Thank you, it does reassure me that you guys think the proportions and symmetry are good. I am very happy with the size of this diamond and as long as I'm confident the light performance on this is good I'll be very happy.
 
It has strong blue Fluo, it appears, and that is cool.

Make sure it is clean. Most of us drop our rings in cleaner every night and rinse in the morning.

Boil water. Take it off heat; watch your hands (boil over warning) and put a few drops of blue dawn and a splash of ammonia in there. Put ring in (you may want to run the ring under warm water to "warm it up" first). Let soak for a good 30 mins to an hour. Scrub with old toothbrush. Put in warm water for a rinse soak. Blow dry with hair dryer.

Let us know if the stone's appearance improved.
 
Cleaning the ring is a great idea, I will give that a try and see how it goes! I did consider buying a loupe but then Im going to end up spending my days just staring at my rock...
 
Welcome to your newest obsession :appl:
 
There is a thread about B/G/M around here somewhere if cleaning doesn't improve it.... I'll try to find it.
 
Hrm I did not consider whether the stone could just be hazy or have some sort of tinge to it. It's pretty hard to tell just looking at it and without anything to compare it to.

I'll try to give it a thorough clean and see how that affects the appearance of the stone. Otherwise I also thought about taking it to an appraiser, although it seems a bit ridiculous to spend almost 10-20% the cost of the diamond to have it evaluated. I might as well just get a better diamond..
 
I think it's beautiful and lovely on you. I think diamonds just reflect light differently in different lights.
 
I agree with gm89uk's assessment based in these photos. I dont see any persistantly dark area and the stone seems to have good contrast patterns.

Diamonds tend to show a great light return outdoor because the entire hemisphere is evenly bright and you have dispersed bright light coming from all angles (unless you are surrounded by buildngs and trees). You are literally inside a giant idealscope.

However, in an indoor environment, you have light fixtures only in a limited number of location, and intense light comes from certain angles only. And each facet of a diamond draws and reflect light from a very specific narrow range of angles only.

Think of a mirror. You need to angle it perfectly to see what you want to see. Depending on where your stone faces (lamp, wall, furniture, black sofa, yourself), if off by even one tenth of a degree, a facet or a set of facets can go dark.

To assess a diamind on light return , see the links below. Roll up a piece of paper, or use a funnel or white pvc tube.

You say that like it's a problem :lol: I love the blue fluoro - super jealous as I wish my stone glowed like that! I think you nailed it first time with that, it's really lovely.
 
I cleaned the ring and it makes it look really sparkly :). Although it seems to attract smudges again almost immediately, I borrowed a friend's biology loupe and can see all these little smudges on it after only a little while. oh well..

I tried taking some pictures using a funnel, but i can never get the angle and focus right on my crappy little mobile camera.

Keep it keep it keep it!Beautiful diamond!!! Wear it in good health!
 
The arrows look wash out because of tilt, shooting distance, or the funnel is too big.
The images are grainy because the overall lighting condition is too dim. Ideally, you want to do this in a well lit environment or use a lamp to illuminate the funnel/paper. Think of photographer's white photobox.
Some images are out of focus, because the condition is too dim or you shoot the photo too close, below the minimum focus distance.
I know. It is hard, even for experienced proconsumers and vendors.

Having that said, again, I don't see any noticeably dark area.

Regarding "dark patches in the middle", are you talking about the table reflection, the inner circle?
This area consists of 8 pavilion facets, each drawing and reflecting light from a different direction from a VERY specific angle. So, depending on the lighting condition and what each facet is facing, the entire area can go dark, go bright, or go partially bright/dark. Simply put, do not worry about it.

Lastly, it is a keeper for me
 
If you happen to retun it, remember it has to be back at Blue Nile on or before day 30.

After you cleaned it, did the dark patch go away?

It appears to be a great diamond to me.
 
Thanks everyone for all the advice. :)

After I cleaned it it looked a lot sparklier and livelier, but I was still seeing some gray areas in specific lighting, mostly dark patches around the table reflection, and sometimes around the edges. Although having read a bit more I'm suspecting this might be my reflection I'm seeing.

I am still just within the 30 day return period although getting close to it, but from what everyone is saying, I'll probably keep this one. Not having any experience with diamonds and sort of realizing after we ordered it that this diamond is going to be the one I'll have forever probably made me over think this more than I should.
 
So since I found myself obsessively wondering about whether there were any issues with my stone I ordered an ideal and aset scope. I found it very difficult to get it aligned and flat, and with the ring already mounted I'm not sure how much of an impact it has on the images.

To my very untrained eye these images seem okay, but I don't know if there's something I'm doing wrong or something I'm not spotting. I found that the image varied a lot depending on just a tiny bit of movement, and I'm wondering if I could be making the image look better than it should because I did not align it properly.

Would any of you wonderful people be able to help me with a bit of insight into how I should be viewing the stone/taking pictures?

Your stone looks old amazing to me, great find!!!
 
Wowsers! Those are some pretty damn good scope images of the mounted stone! Looks like good saturation throughout and pretty good optical symmetry too!
 
Gorgeous diamond!!!
 
Your second pic looks pretty much perfect. I would be pretty delighted with my glowy blue stone if I were you
 
Great stone!
 
Thank you for the feedback. I'm very happy to hear everyone thinks the stone looks good. I wasnt sure if I was looking at them and taking the pictures properly but it is a relief to know there is nothing obviously wrong with it that anyone can spot. :)
 
Just chiming in to say I think it's totally lovely.
 
I expected this level of IS and ASET images. Told ya it is a great stone.
