Featured Gem TANZANITE

Lush blue velvet. Rich royal purple. Exotic tanzanite is found in only one place on earth, near majestic Kilimanjaro.

Named for Tanzania, the country where it was discovered in 1967, tanzanite is the blue-to-violet or purple variety of the mineral zoisite. It's become one of the most popular of colored gemstones.


Found in just one place on earth, tanzanite is a relatively recent discovery. This blue variety of zoisite was named for Tanzania, the country where it was found, by Tiffany & Co. Because crystals show different colors depending on viewing direction, cutters can choose bluish purple or the more favored pure blue or violetish blue hue depending on how much weight they want to retain from the rough.
