Knocking on heaven's door. This extraordinary gem formed in the earth about 585 million years ago during the mid-Ediacaran Period. Yet Tanzanite was unknown until the late 1960s. The first African specimens of this new form of Zoisite soon made their way to Tiffany & Company, where shrewd marketers coined the gem's name and created the campaign "Found in only two places on earth: Tanzania and Tiffany." The lilac-periwinkle blue shade is indeed heavenly, and this large oval cut at almost 24 carats is unsurpassed for fire. Call us for your free design consultation. Gemstone Details
