Accurate appraisal for Gabrielle cut?

Hi! My husband gave me a Gabrielle cut round diamond solitaire engagement ring in 2001. It is 3/4 carats. I love it, it is the brightest and sparkliest diamond. I read a little about the cut (105 facets, developed by Gabi Tolkowsky). I have the original jewelry store appraisal and cost and facts, listing that it’s a Gabrielle cut(he paid just under 7k). I was very bummed out when I took it into to my current jeweler and it appraised at a third of that. The appraisal does mention that it has 105 cuts but not that it is a Gabrielle cut. So….
-I’m worried about the replacement cost in appraisal. I don’t even see these for sale anymore? Do they sell them anywhere? It def doesn’t look like a regular .75 carats solitaire. How can I get an appraisal that reflects that? Are Gabrielle cuts for sale out there and do they demand more?
-Does this particular branded cut increase its value? If so how can I get an appraisal that reflects that? Neither appraisal I have is GIA but from the jeweler at small town jewelry stores.
Thanks! IMG_0364.jpeg
 
Pricescope has a list of appraisers: https://www.pricescope.com/appraisers?searchby=name&searchvalue= You can search by state. Before I would send off a diamond to an appraiser I would call and inquire whether or not they were familiar with the Gabrielle cut, if they are GIA 'trained', what they would charge, how would shipping and insurance be handled, etc. There are a couple of appraisers who sometimes post here also.
 
I have never heard of this cut of diamond or a company by that name. You can always submit the stone to GIA for a grading report. Having more facets - not cuts - does not make it more valuable. At least with the grading report, they might be able to give you an accurate assessment of the diamond. It will be up to GIA to determine whether or not they would grade the diamond. They will not assign a dollar value - that would be up to an accredited appraiser. GIA would give you a color and clarity grade. Natural diamond prices have risen and fallen since 2001 so what you paid in 2001 is really not relevant to its value today. This sort of reminds me of the Leo Diamond that Kay Jewelers and Jared’s has sold in the past. If you love the diamond and want to keep it, you might just want to get it appraised and insure it for a certain dollar amount. Not sure where it was purchased or if they still sell such a thing, but I would guess that a like replacement would be hard to come by. Always best to buy any diamond with a GIA grading report so that you know exactly what you are buying. Good luck and keep us posted.

That is neat it was hand cut!!
Edited to ask- would being hand cut/timeframe/location of such work increase value?

Extra facet fancy cuts are tricky.
What you have is a diamond with potentially 105 facets and no grading report.
Without digging into it deeper, verifying design and checking for a any identification on the diamond itself to prove its a branded cut there will be a lower value.
All that can be done, but without it then yes the value will be low because it would be valued on fancy cut rap list price then lowered even more because of no report.
New it probably traded on the higher priced round cut rap list price.
So to get a reasonable value takes some homework by the appraiser and the no report is going to reduce the value.

Find an appraiser used to dealing with extra facet fancy cuts.
I'm paging 2 of the best appraisers in the US.

Thank you! The documentation I have from the original sale has a report from the store he bought it at. It lists the measurements, cut, color, clarity, etc., it uses ags terminology but not sure if it’s an official ags report(I’ll pull it out later and share). I did call the store but they have since merged with another store and don’t have any other records from that period anymore.

If its an official AGS report that changes things a bit but it still takes a skilled appraiser who is willing to put in some work..
 
During the time such extra facet count round diamonds were being promoted by many retailers, the attempt was made to convince consumers of the added value the brilliance and extra facets added. A number of consumers bought into the marketing, but you can see that the success of these products was not long lived or spectacular. Most of these diam0onds were purchased by cutters already shaped into standard brilliant cuts and facets were added. Actual evidence of these stones being better in some way was sketchy and time has told the story, since few are marketed and fewer are being cut with more facets. Many branded cuts with added facets have come and gone.

Replacing your diamond with an ACA diamond from a firm like Whiteflash would be the way to replace the stone with one that has the best range of brilliance, sparkle and contrast. Basing a replacement value on that kind of readily available replacement would provide sufficient insurance coverage. If you searched diligently for a Gabrielle Cut, you might find one. Pricing for a replacement with identical diamond of identical cut would be impractical since no ready market is available to research.
