Hello Everyone,

This is my first topic, although I have been lurking for 7!!!! years.

I have a large heirloom diamond ring which I'm thinking of re-cutting. I'm just wondering if this is worth doing or would it be just best to leave the diamond as it is. It is aprox. 5.3 carats, round brilliant, vs2, colour N-P. These are all estimates as I haven't got certificates for this stone. My Jeweller said it looks like it has been cut to retain size and that the table is large. I know that this stone has been in my family from about the 1950's. I'm' afraid I couldn't really capture it's beauty on my I pad. :|

The setting is not original.

I really would like to have re-cut it in to an OEC. What do you guys think?

Many thanks for any responses!

Hi Pikku,

Nice you have come out of lurkdom, hello!

Until some of the others log on, if you have time please, would you mind uploading a photo directly for me to this thread? I am having trouble viewing attachments as I can't access them for some reason, but we are working on finding out why and I hope this issue will be resolved soon.

Meanwhile, a few things to consider. By far your best bet is to ship the stone to an expert for their opinion. Now bear with me as I am trying to get up to speed as I haven't been back on the forums very long and this is something I need to check up on, who is offering recutting services etc. But you could contact Brian Gavin, Infinity Diamonds might be able to offer assistance but again I will need to check on that, Wink Jones might be able to help too, he is an Infinity dealer also. I believe Brian used to offer a recutting service and might still do so.

A few basic points to consider but of course the only person to properly advise will be an expert with your diamond in hand. Things they might want to discuss are if you would like the diamond to have a lab report after recutting, this you definitely might want to consider with a stone of that size.

- Loss of carat weight after recutting. This might depend on the type of cut you want and the amount of cut precision needed to achieve the desired effect. A precision recut to try to maximize the stone's beauty and optics could well mean more loss of weight than a recut that is less precise, but offers some visual and physical improvement. The cutter might even suggest another type of cut might be preferable.

- Colour after recutting. The stone is N-P in colour, some cutting techniques might minimize or enhance the warmth. After recut and the stone is sent for a lab report, would it bother you, as an example only, if it graded higher by a colour grade or so or lower down the scale? The clarity grade might even change depending on where the grade making inclusion is located.

Loss of the diamond. There is a risk when having a diamond recut, albeit a small one, but it isn't unheard of for a stone to break or shatter during the process. To the best of my knowledge, the owner of the stone assumes the risk, usually the cutter takes no responsibility should loss or damage occur. This is again something you would need to clarify when the diamond has been assessed in person by the expert that will do the work.

I hope the above gives you a few things to consider, but the professional you choose that has seen the diamond is really going to be the best and only person to advise on whether you should proceed and how to do so. They will discuss the above mentioned points with you and a whole lot more, then you will be in a good position to decide how to proceed once you have consulted the expert, should you wish to do so.
 
Thank you for your response! Here are a few pics.

You are most welcome! Unfortunately, I still can't see anything for photos, are they showing for you on the page directly? I hope I can get this sorted out soon, but we will work on it.
 
They are showing up for me Lorelei. Its a lovely stone but I do see the large table.

I think *I* would have it sent in to have it evaluated then make a decision based on what they say.

If it can be cut without loosing too much weight and make it a better performer then it might be worth it.
They also need to look at any inclusions to see if a recut is possible.

Its a really lovely stone and so nice that its an heirloom.
 
Thanks Ty, I hope I can get this sorted out soon, it's being a bit of a pain. Jealous you can see that lovely sounding rock! ;(
 
Do you know the stone's dimensions? Someone who is familiar with cutting may be able to tell something from that. I'm thinking that your diamond might be shallow depth + large table. And that it might lose less weight cut to a modern H&A 60/60 type. OEC is a deep stone, with a high % crown and small table. I think if you try to make a shallow diamond into that, you might wind up with a much smaller diamond because much material will have to be removed. The shape of most OECs is opposite of a shallow diamond. I have one that is shallow and spready for its weight, but it's not ideal-cut. It windows in one spot.

Wink has a video of a Crafted By Infinity 6.03 Ct. N VVS1

It is my understanding that when a shallow stone is recut to an OEC, it loses A LOT of weight (like up to 30%). I think your diamond is lovely, even with a large table. But I understand your desire to have an OEC (I considered doing the same with mine, which is similar to yours, but with a smaller table and probably lower crown angle), but I decided against it when I was told I could lose a carat and a half (or more) of weight. Regardless, what an inheritance! Enjoy!

Also, I love the simple setting.
 
Hi, annoyingly just lost two posts!

Thank you for replying Lorelei(my first post and first reply from the legend herself!), TyTy,TC and Tourmaline.

It is shallow as apparently it faces up more like a six carat stone. It is very big so I don't mind losing some size as I don't feel comfortable wearing it as it is. That video was interesting, thank you. And the price of that stone compared to the rough valuation I was given recently is a lot higher. So maybe it would be sensible to re-cut, although the thought of it exploding on the cutting table is pretty terrifying....

I am based in the UK, anyone know of a UK cutter?

Thanks again x
 
I will also have it certified properly once I've decided on re-cutting.
 
I would seriously consider a Crafted By Infinity re-cut - they are based in Antwerp so you can fly there from the UK for about 130 quid and meet the people face-to-face, and their stones are some of the best cut stones available, going from what I have read on here!

Check out HighPerformanceDiamonds, run by Wink Jones on here - he may be able to make contact with Antwerp for you and set up a meeting to discuss your options and get the stone appraised by them for re-cut potential :)

Ex idea... :appl: get in touch with Paul... :appl:
 
If you want it recut into an OEC, maybe get in touch with Jonathan at good old gold to see about sending it to Yoram. I would guess an OEC, with it's smaller table and deeper depth, would end up being a lot smaller than the current weight. But you'll end up with an excellent light performance diamond!

If you're open to round brilliants, no question that crafted by infinity is the way to go.

You are too kind, thank you!

As you are in on my side of the pond, Paul Slegers from Infinity is most definitely your man. As mentioned above, he hails from Antwerp but that shouldn't pose a problem. If he can't help, as the old advert used to say, was it for the AA now*scratches head*....he will know a man who can! http://www.infinitydiamonds.be/
 
Thank you a for the advice, I think I will make contact with Paul directly.

Have lovely weekend, should be sunny, here at least!

You are most welcome Pikku, we are glad to help. That sounds like a plan contacting Paul directly, he is a great guy and will be able to advise. I am up and running now thanks to admin's help, I can now see the diamond. It's beautiful and I love the warmth, but no harm at all in seeing what type of transformation might be possible. If not, you still have a fantastic huge diamond - win win!

Enjoy your weekend and keep us posted. :wavey:

PS - yes, they said it's going to be hot here - yuck. I don't like the heat, snow, now that's a different matter... :cheeky:
 
If you want it cut into an OEC, you need to contact Jonathan at Good Old Gold. He can best advise you about weight loss, etc. He has some outstanding cutters for his AVR line which are newly cut OEC's but with excellent light return! Furthermore, I am pretty sure he has the computer programs to plan the recuts.

As I would not wear a diamond that large, I absolutely would be thrilled to have it recut into an AVR/OEC!!! I think the color is better suited towards an antique cut, too!
 
Hi OP,

That is one beautiful stone. I would also go the Antwerp route for a top modern cut instead of OEC for this stone, if you like modern cuts; this stone has potential to be made into something really stunning. Yes, it is best to have it evaluated of course because you really do not want any inclusions that might end up in the stone shaterring or breaking in half during recutting. Great points about the color grade changing, that and the clarity grade could go up if this stone is recut depending on many factors of course. This is a really interesting project and I am very curious how it develops out, please keep us posted. Let me also say welcome, glad you came out of lurking and also that you are very fortunate to know such an heirloom.
