Tanzanite: Blue Gem Exquisite Beauty

February 12, 2018 · 3 min read

Tanzanite is one of the most unique and desirable gemstones that is currently available. It is rare and precious. It can only be found in the foothills of Mount Kilimanjaro in Tanzania, East Africa region hence the name Tanzanite.

There are a few mining bases located around the Mererani hills at the foot of the mountain in the city of Arusha. According to experts, the current supply of gemstones is going down. This unique stone will be a rare commodity in the next 25 to 30 years making it the gemstone of the generation.

Chances are high that this will be the last generation to wear and buy Tanzanite gemstones as first time owners before the supply runs out. The gemstones limited supply have made it a thousand times more rare than diamonds making it all the more special.

The History of Tanzanite

Majority of the world’s most popular gemstones have been in existence and put to use for hundreds of years. Tanzanite, on the other hand, came into the limelight a few years ago. This is despite being formed about 585 million years ago and was not used in commercial quantities until the early 1960s.

In 1967, a Maasai herder came across the gemstones in Tanzania on the ground and he thought that they were just colorful sapphires which were later confirmed to be a new gemstone. New York’s celebrated jewelers Tiffany & Co. popularised the new gemstone about a year after its discovery and coined its new name Tanzanite. 

A Vibrant Stone

Tanzanite is trichroic in nature, which means that it can radiate different colors when positioned in different angles. For instance, under the midday sun it can radiate a blue hue and later on in the course of the day it will radiate different colors. These colors include yellow, purple and red all of which combined give it an overall vibrant purplish color.

Occasionally people can buy Tanzanite jewellery that is green or pink in color. However, the majority of Tanzanite jewelry being sold today has a blue color. The blue color of Tanzanite is caused by small amounts of vanadium within its zoisite mineral structure.

The heat treatment that Tanzanite jewelry goes through is very mild when compared to processes carried out for other stones including sapphires and rubies. You can visit a world-class Museum in Tanzania at the Tanzanite Experience to have a close-up view of the magical Tanzanite gemstones.

Aside from its vibrant color, Tanzanite gemstones are extremely durable that is why they are sold as earrings, pendants and other jewelry items. They are resistant to impact and abrasions and can last for multiple generations. They come in different sizes. The small stones are cut for sale and larger stones are showcased in showrooms to be purchased by collectors and investors.
