History of Tanzanite
Tanzanite was first commercially discovered in 1967. A Masai tribesman and part-time gold prospector found the stone while mining and thought the gem might be blue peridot or similar. After showing the stones to other miners and geologists, it was determined to be a new variety of the mineral zoisite. It quickly became a part of many jewelers' collections. Still, retail giant Tiffany and Co. believed the name was not catchy enough for consumers, so they renamed the stone tanzanite after its mother country and used it for their marketing campaigns.
Since its discovery, tanzanite has only been found in a small area in the foothills of Mt. Kilimanjaro, approximately four kilometers wide and two kilometers long. It is believed that the geological conditions required to form this stone are so rare that it will never be discovered anywhere else in the world. Tanzanite is said to be one thousand times rarer than diamonds, and if it could be used in industrial settings, it would be equally more valuable than diamonds.
Adding to its value is the rapidly depleting supply of natural tanzanite. Geologists estimate that at the current mining rate, most of the world's primary tanzanite market will be depleted within a few decades. As tanzanite becomes less and less common, its prices will continue to climb.
Tanzanite is also one of the few gemstones with a naturally occurring ultramarine color. It and sapphire are the two favorite blue stones in the gem marketplace. It is often debated which was used to craft the famous Heart of the Ocean necklace in James Cameron's Titanic. In the movie, Kate Winslet's character Rose claims it is a blue diamond, but the actual necklace used in the film is rumored to be a rare tanzanite gem.
Tanzanite characteristics
Tanzanite is a variety of the mineral zoisite, ranging from a dull brown to pink, green, and, of course, the famous blue. Tanzanite is not always blue or purple in hue but is often naturally treated with heat to change its color chemically. While the heating process does not damage the stone or change its value, naturally blue and purple tanzanites are sold wholesale at higher prices due to their rarity and ready-for-market use.
Typically, ultramarine tanzanites are more valuable than lighter shades of blue, periwinkle, and lavender. As a collector, both blue and purple hues are equally beautiful, and the best selection should be based on your personal style. Tanzanite owes much of its beauty to an unusual gemological property called pleochroism—the ability to exhibit more than one color. When viewed from different angles, tanzanite can look blue, violet, purple, bronze, or gray. The more pleochroic the gem typically increases the value of the stone. Stones with this quality tend to be of higher value and add a bit of sparkle every time you wear one.
Tanzanite is rated between 6.0-7.0 on the Mohs Hardness Scale, making it incredibly durable for everyday use. When paired with a sterling silver or gold setting, it will last over the generations and become a beautiful heirloom gift.

Tanzanite Care & Cleaning
Tanzanite is a hardy stone for everyday use but will need careful cleaning and care if it is to last for several decades. Protect your jewelry in a jewelry box when not in use to minimize damage. In addition, it should be protected from sunlight, dust, and other air contaminants to resist fading or damage to the setting.
Tanzanite should be washed after use with gentle soap and water only. It should never be steam cleaned, put in an ultrasonic cleaner, or generally exposed to extreme temperatures. These can quickly damage your gem as well as the sterling silver or gold setting.
