I've not heard of this before. Is this a real stone? Should I bid on this? LOL

I won't bid on this. These Thai dealers on eBay should immediately be suspect. Unless you have a way to test this after you get it, its best not to waste your money and time.

Hydrogrossular does exist in green to blue green commonly, but I have only seen it in cab form and never faceted. Some of the sunset, peachy orange and red colored hydrogrossular can be very pretty and expensive. Sometimes people call the green variety "african jade".

I'm very interested in hydrogrossular and have been cutting quite a bit of variously-colored material lately. The image (complete with camera reflection) shows a fine orangy-red stone of 12+ carats I picked up on a recent visit to Idar-Oberstein, Germany.

I've learned to never say "never" in gemology but I believe hydrogrossular only occurs as a microcrystalline aggregate (massive). So a single-crystal type capable of yielding a faceted gem of the size and clarity shown would be unlikely.

However one garnet authority [Rouse] says the translucency of the finest gem specimens is very high, approaching transparency, with exceptional green color. It should be noted that another faceted "hydrogrossular" offered by the same seller has a certificate from a gem lab (unknown to me) that identifies it as hydrogrossular, so...? But that stone doesn't look aat all like the first.

Rick,

That piece of hydrogrossular is incredible looking! Love that color. Do you sell your pieces?

Well, against better reason I bidded on the stone and 'accidentally' won the auction. But the more i look at the picture the more it looks like peridot. It even has what appears to be a carbon spot. So I guess i'm just gonna tell the vendor no thanks and let him give me negative feed back.

I didn't notice if they have a return policy, but if you get the stone, and it turns out to be peridot instead of garnet when you test it, then you have a viable complaint against them for fraud. :?

I would at least take the gem and find out what it is. If it's not what it was represented as, you can warn others through negative feedback.


Hmm ... just a thought -- Wouldn't it be funny if it turned out to be a tsavorite? You would make out like a bandit! :D

Yeah, yall are probably right. I'll go ahead and pay for the stone and have it checked out when I get it. I'll post an update when that is done.

Thanks for your comments

Jason

<Smile> Yes Ben, I definitely engage in commerce. This is one of the best red hydros I've seen so far. Due to the nature of digital images and monitors it's hard to know what color you're seeing but it looks right on my monitor.

Jason.
Make sure you pay with a credit card so when you find out it is NOT hydrogrossular you can get the credit card company to withhold payment.
Hydrogrossular garnet is never transparent is it? It was my understanding it is translucent to opaque. :?

I received this stone in the mail today. It looks exactly like it does in the pictures. Unfortunately I still have no clue what it really is sooooooooo our fearless leader Barbra, has agreed to take a look at it and see if she can give us an identification.

We'll let you all know the results when they are in.
