Are you thinking it might be Paraiba?
I doubt it, but wouldn''t it be something if it was?![]()

Looks green in the picture. Possibly emerald? WOW!

Paraiba tourmaline was first discovered in 1989 (Brazil), and this ring looks like it''s probably older than that.
It has the look of indicolite (bluish green) tourmaline, which is a classy stone in its own right.
My first guess would be indicolite tourmaline in a platinum setting (head), while my second guess would be synthetic spinel in a silver setting.
You might try playing around with the Visual Optics technique listed in the FAQ section to see if you can tell whether it is doubly refractive or singly refractive. Double would further point to indicolite, while single would further point to spinel. Neither result would be conclusive though because there are other possibilities within each category.
Pretty stone.
I posted my blue zircon ring recently in this forum.... it is not green at all though like this stone. Of course I have no idea what constitutes blue zircon LOL I think this stone of yours is pretty - needs to be spiffed up a bit but it''s really a pretty color. I definitely see the aqua in the highlight color but it does have some green in the lowlight areas... could be a dark aqua...Date: 2/19/2007 10:49:33 AM

Could it be blue zircon? Although I would have expected more facet wear. And also, I usually see zircon in the round shape (not cushion like yours).

Sorry, Imisunderstood what you wrote. Thought you were going to get it tested and dispute the ID with someone who wasn''t a gemologist.Date: 2/23/2007 4:39:03 PM

I''m about to sign up for the FGA''s Gemmology foundation course, so I thought a trip to their HQ to pay my fees would be a good move and see if they''d ID it while I''m there. If not - I''m prepared to pay as long as they are qualified.
I''ve now had a nice email from the vendor saying he''s happy to refund, but wanting to know if I can get a 3rd party to confirm so he can go back to the person who sold it to him as 100% tourmaline. The single refraction should confirm that surely?
Just realised RockDoc - the ''not a GG or anything'' referered to the vendor. I wouldn''t ask anyone who wasn''t a GG to ID it for these purposes.
Thanks for all your help everyone - it''s an educational experience if nothing else!![]()
