Tourmaline

First, become acquainted with “Kismet,” a 10.91 carat tourmaline set with diamonds in a platinum ring, by Michael A. Saldivar. This vivid greenish blue (called neon blue in the trade) tourmaline was discovered in Paraíba, Brazil, a locality famous for producing vibrant blue to green tourmalines colored by copper.

Interesting Fact: once abundant in the Southwest (and Arizona in particular), many turquoise mines are becoming depleted as gem quality material grows in popularity across the U.S. and Europe.

Sapphire

Sapphire is the classic blue gemstone and a favorite among many. This brooch features the “Starry Night Sapphire,” a beautiful example of a truly mesmerizing phenomenon: a six-rayed star. This 111.96 carat unheated Burmese blue star sapphire is reminiscent of the blue sky in van Gogh’s painting of the same name and evokes a similar dreamy quality.
