Tanzanite

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

BRIEF INTRO

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.

MERELANI

Tanzanite has only one source: the hills of Merelani in northern Tanzania.

1967

Masai tribesman Ali Juuyawatu is credited with finding the first tanzanite crystal.

PLEOCHROIC

Tilt tanzanite and you’ll see three distinct colors in three crystal directions.

TREATMENTS

There are processes used to alter the color, apparent clarity, or improve the durability of gems. Some gemstones have synthetic counterparts that have essentially the same chemical, physical, and optical properties, but are grown by man in a laboratory.

DECEMBER

Tanzanite is a birthstone for December, along with zircon, turquoise, and blue topaz. Tanzanite is also the gem for a 24th anniversary.

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.
