I did not realize how small the stone was. I cannot use it for the project I wanted, but I am keeping the stone and tru to use it in something else.

was just windowshopping and spotted a couple "Very Uncommons", a tsavorite & a demantoid garnet that were both in a size I was looking for, & that I could very easily pay for -- so figured I would grab the tsavo ASAP and got the demantoid to accompany so they wouldn't be lonely.

The website is well organized and works fast forward and back. Plenty of filters. Each gem is described in detail and you receive the one pictured. Gem material info and sources available. I would like to see more specifics on sources besides country- at least region or state and in the US with Turquiose which mine. Thanks!
