I sell gems via auctions online. I am running into an issue with one of my lots in terms of the auction house agreeing to post it as they don’t believe that the lot is colour change garnet.
I have tested it and given them the RI and explained that it is monochroic under a polariscope. They still want an expert opinion.
I am not quite sure how to proceed as the value is probably only £150 for the lot. It is 5carats of smalls, 1.5-3mm and the colour change is not great in my opinion.
I bought them in Tanzania a few years back and I know the dealers know their stuff. Unfortunately, none of that seems to matter.
To get a stone certified would cost about £60 and I don’t know if that would cover the lot. It doesn’t seem financially viable to do this.
Any advice on this would be appreciated. I can upload pictures and give specifics if anyone needs them.
Thanks in advance.
