Tsavorite Alternate Birthstone for May A Variety of Grossular Garnet Tsavorite is a variety of green grossular garnet. It is one of the newest of the precious gemstones discovered in 1967. It occurs in shades of green ranging from spring-like pale green to intensely bluish green to deep forest green. Often compared to emerald, tsavorite is a superior choice in many ways. Tsavorite is not only more durable than emeralds, it is also more highly dispersive and refractive. Tsavorites are not treated with oils or resins as emeralds typically are.

A Large Unnamed Star Sapphire 

 This large star sapphire has no apparent name. It appeared at Sotheby's Auction House in April of 2002. Here is what they had to say about it: 

"Star sapphire and diamond pendant-brooch, circa 1955. The large oval-shaped star sapphire cabochon weighing approximately 145.00 carats, within a frame set with 23 marquise-shaped, 1 round and 1 kite-shaped diamond weighing a total of approximately 23.00 carats, mounted in platinum, with pendant hook."



The piece had an estimate of $30,000 to $40,000. The stone has no name but due to its immense size and quality, I felt it belonged on these webpages..
