Anyone heard of this?

Blue-orange ametrine. LINK - looks quite spectacular in this photo, but I wonder if it''s a natural material.

I have serious doubts thet are natural. 9999.99% chance they are synthetics.

It sure is spectacular, and no, I have not seen such an ametrine. With all the synthetic ametrines out there, I am always leery of buying one.

I''ve seen hundreds of them, they come in all colors (though rarely those found in nature). They are a staple offering on eBay. They are all listed as natural unheated ametrine from Bolivia or Brazil. Don''t be leery about buying one, you''re guaranteed to be getting a 100% hydrothermal quartz. You don''t have to worry too much about clarity either, they''re all graded IF. Enjoy.
