With a durability of 6.5 on the Mohs scale, and an exotic country of discovery (Tanzania), the birthstone known as Tanzanite is a stunning addition to your wardrobe. Set in rings, earrings, necklaces, and more, tanzanite was originally discovered in the 1960s in Mererani Hills, Tanzania. Naturally-formed tanzanite is quite rare as it has never been found anywhere else on the planet.
Originally mistaken for peridot, tanzanite is a unique stone that can be found in violet blues, and reddish browns if left untreated by heat. Originally marketed by Tiffany & Co, it was known as "blue zoisite" but when that was deemed an unmarketable name, it was so dubbed after its country of origin.
One of the most famous tanzanite pieces of jewelry is the tiara known as the Queen of Kilimanjaro, featuring the world’s largest faceted tanzanite (242 carats) on 18 karat white gold, encircled by 803 rare tsavorite garnets and 913 brilliant-cut diamonds. it is currently in the possession of Michael Scott, who has allowed the item to go on display with alongside more of this collection, on occasion.
One of December's notable birthstones (added to the list in 2002), tanzanite is also recognized as the 24th anniversary gemstone.
