I’m a gem dealer (not my main profession). I have recently come across one of the rarest gemstones I have ever seen (a unique type of color-changing garnets). They are totally different from other color-changing garnets and they change color by rotating the stone, so there are two colors in the gemstone and depending on the angle you look at the stone you will see a different color. It is the most amazing effect I have ever seen in a gemstone. In natural light, they go from orange to lime green or orange to yellow just by changing their orientation. Interestingly the intensity of daylight can shift their colors a bit too and some of them have the alexandrite effect where the green changes to yellow in incandescent light. As I deal with fine cut gems, I will be cutting some pieces but I feel that they are of great importance to collectors, museums, gemologists, and researchers. As I mainly deal with cut gems, I'm not very familiar with collectors that buy the rough. I wanted advice on where I could find interested collectors, gemologists ... etc. Collectors don't have online profiles so how should I find them?

How do collectors find the pieces they are looking for? Do you have to see the piece, is it word of mouth or through exhibitions, or just online purchases? I would be really thankful to know more about how this industry works.

I generally like to see the material before I buy it. Sometimes, if I know a dealer well, I will buy direct from them without seeing it before. The Tucson show is where I spend the most money, generally.

How sure are you that these are garnets? Have you shown them to a recognized gemology lab? What test have you run? Can you show us some pictures?

Agree with 1bwanna, what have you done to classify your garnets as a gem like no other color change, color shift garnet? Most if not all true collectors of gemstones are savy and will not bend to sales fluff. They are knowledgeable persons. Tucson is a good place to start, reputation, years in the biz can help. Not to be negative towards your post but a reputable auction house is a great leap to a collectors eye. You will need the former in any case.

What you seem to be describing is pleochroism in a possibly color changing gem.
Does not sound like garnet to me.
Have you considered submitting a sample to Gem-A or the GIA?
If indeed it is a new, wondrous, collectible material, they will certainly do an article on it for their publications.

That would be the ultimate for you in free publicity and getting the word out.

As I vaguely recall, in the not too distant past, we had another member who was trying to verify the existence of his pleochroic garnet. :smt017 Any one else remember?

There is similar ceramic glass material that is being sold in East Africa as rough color change garnet.

Not saying that is what this is until I see a piece. But it does raise my suspicions. Not sure how any stone in the cubic system exhibits pleochroism.

Thanks everyone for replying. I found the comments & suggestions really helpful so far and am looking forward to hearing more. The reason I say that they are garnets is because of the crystal shape of the gemstones. There are also Tourmaline pieces with same effect which I have a few pieces of too, coming out of the same mines (stones coming directly from the mine). I recently received the pieces and I plan to send them to the lab for verification soon. I have uploaded a video of a piece so people replying to my post can give more detailed replies.

That's not a garnet, luv.
Please send to a reputable lab and get a proper ID.
Good luck.
You may have something else rare and desirable and you don't even know it :wink:

Definitely not garnet. Also not glass which is great news. Should be an easy in person.
