0.68ct Genuine Tanzanite 925 Sterling Silver + 18kt Gold

Probably the most noteworthy tanzanite gemstone is the "Queen of Kilimanjaro", which is set into a white gold tiara along with 803 garnets and 913 diamonds. It is thought to be one of the world's largest faceted tanzanite gemstones, and weighs 242 carats.

In the Smithsonian Natural Museum of Natural History collection there is a 122.70 carat tanzanite gemstone. Also in the Smithsonian collection is a Schneider tanzanite ring, which features a 12.11 carat tanzanite gemstone, and a Petersen tanzanite brooch with a pair of matching tanzanite gemstones, weighing a total of 30 carats.

Tanzanite has been worn by many Hollywood stars such as Cate Blanchett, who wore a Chopard tanzanite necklace to the Cannes Film Festival. Penelope Cruz's engagement ring has a tanzanite central stone and Anne Hathaway wore tanzanite drop earrings to complement her electric blue Armani dress during the 2011 Oscars.
