CAT'S-EYE REBELLITE, PINK SAPPHIRE AND DIAMOND RING


We haven't seen lots of cat's-eye rubellite tourmaline in jewelry market. Cat's-eye green tourmaline is more common than other types of tourmaline. In the recent Sothebys' auction in Hong Kong, we found a cabochon cat's eye rubellite jewelry. The cat's-eye rubellite tourmaline weighing 8.41 carats surrounded by brilliant-cut diamond alternately-set with pink sapphires mounted in 18 karat white gold.

Largest Cut Paraiba Tourmaline Gemstone 191.87 Carats


The "Ethereal Carolina Divine Paraiba" is the largest cut paraiba tourmaline. It has a weight of 191.87 carats and measures 36.44 x 33.75 x 21.85 mm. This paraiba tourmaline is valued at between $25 million and $125 million. Montreal financier Vincent Boucher is the owner.
It is hard to believe to see this record but the tourmaline was already certified in June, 2009 by the Gemological Institute of America. This paraiba tourmaline has neon blue color and is a flawless stone. Without a chance to see the GIA's certification, there is a question whether the tourmaline has been heat-treated.
