I just got this in the mail today! It is a blue/greeen mozambique tourmaline.
1.72cts, VS, Portuguese oval.
The vendor didnt mention anything about copper content, but this stone sure does glow (more them my certified cuprian tourmaline actually). It has a small window, but it is really small.
LOL I am broke now. I need to stop buying gems so I can set a couple! I expected it to be more bland (like your typical green or blue tourmaline), but was really shocked when I opened it at how flashy it is.
I got it from thaigemstore.com. I decided to try them out and I am glad I did!!!
Here is the vendor listing
