Zultanite of 54.73 carats on an 18K gold ring

[flo_ch]

Hello Everybody,

I hope that you are doing well.

We have in my family a unique 18k gold ring, set with an exceptional natural color-changing Zultanite stone of 54.73 carats, surrounded by 22 diamond.

The Zultanite has been expertized and its authenticity proven. I know that a natural Zultanite from this size is pretty rare.

I tried to get an evaluation of this piece everywhere, but couldn't fine somebody who was able to evaluate this piece.

After and evaluation, we would like to sell this unique piece, do you know where there are collectors who might be interested in Zultanite in particular ?

Thanks for your help.

Have you thought about selling on eBay where it would be authenticated by a 3rd party?. Your lab reports are coming up blank for me.

The authentification is not needed as one of them provide from Gubelin which is a trustful institute, however they don't make any valuation.

I didn't want to put it for example on Ebay, as I don't have a proper evaluation for the piece.

I don’t understand how you’re ready to sell to a collector but don’t have enough information or idea of value to sell on eBay.

I think if you search through the appraisers on this website you can find a GIA appraiser who could appraise your ring.

Good luck!

You could try having the stone and ring evaluated together as a piece for its replacement value for insurance purposes as a guide, by a local jeweller acredited to perform such evaluation.

Bewarned though that such an evaluation is often much more than the saleable value for a piece of second-hand jewellery, as I have found out myself based on my own experiences.

Being a unique and modern gemstone there isn’t much “price data” available. So an appraiser isn’t going to have that to assist them to calculate value. Also being a large size is unusual. Not sure if being larger size adds a lot to the value (ie does the per carat value increase).
I think Zultanite is a pretty niche market, it’s a fascinating gemstone but it’s basically unknown to the general public.
You might need a specialist gem auction to realise full potential but the selling fees are high.

Having an Internet browse, over 50 carats is indeed rare, also very expensive apparently. The asking price for a 40 odd carat Zultanite is like $400,000. Of course what the seller wants and if someone will buy at that price ?????
So yes, I think you’re going to need a specialised market to realise proper value. Unfortunately, and as with many natural gemstones, there is a laboratory version which costs under $100 for huge ones on eBay.

Thanks to all for your replies.

Indeed, this is a very niche market and I don't find any company ready to evaluate it.

Do you know somewhere I can get a specialist in that kind of stone who whould know the value of it ?

Indeed also, there are not a lot of buyer of such new stone, and this is why I am struggling to find a place where after an evaluation, I can try to sell it, maybe indeed for colletors.

The only point I know is that a stone from this size is very very rare. According to studies, like 95% of those stones are below 2-3 carats, and online like 10 discover until now above 20 carats (the biggest one found today on internat are 30 carats and 80 carats).
