Gift of Mark and Nancy Schneider in 2001.

This beautiful 12.11ct tanzanite gemstone is set in an award-winning platinum and diamond ring designed by Mark Schneider. In 1967, violet-blue crystals of the mineral zoisite were discovered in Tanzania. Tiffany & Co. marketed the new zoisite gems under the name Tanzanite, and since its discovery, the gem has steadily increased in popularity and value. This fancy-cut triangular tanzanite gem exhibits the prized deep sapphire-blue color with highlights of intense violet. This extraordinary ring is the first piece of tanzanite jewelry accessioned into the National Gem Collection.
