Tanzanite is a rare and exquisite gemstone that captivates the eyes with its vibrant hues and remarkable beauty. It is renowned for its deep blue-violet color, which is unlike any other gemstone. Tanzanite's unique color, combined with its scarcity and captivating brilliance, has earned it a special place in the world of gemstones. The story of tanzanite begins in Tanzania, East Africa, where it was first discovered in 1967. It is believed to be one of the rarest gemstones in the world, as it is found only in a small mining area near the foothills of Mount Kilimanjaro. This region's geology and unique conditions contributed to the formation of tanzanite over millions of years. One of the most remarkable characteristics of tanzanite is its pleochroism, which means it can display different colors when viewed from different angles. In the case of tanzanite, it can exhibit shades of blue, violet, and sometimes even burgundy or brown. This color play adds to its allure and makes each tanzanite gemstone truly unique.


Tanzanite is a variety of the mineral zoisite and owes its mesmerizing color to the presence of vanadium. Its intense blue-violet hues are highly sought after, especially in larger sizes and high clarity. Due to its rarity, tanzanite is often considered a collector's gemstone and holds significant value in the market.

Hardness and strength

Tanzanite has a hardness of around 6.5 to 7 on the Mohs scale of mineral hardness. This places it in the range of medium hardness. While tanzanite is not as hard as some other gemstones like diamonds (which have a hardness of 10), it is still considered suitable for most types of jewelry. However, due to its slightly lower hardness, tanzanite should be handled with care to avoid scratching or chipping.


  • Heat Treatment: Heat treatment is the most prevalent and accepted treatment for tanzanite. It involves heating the gemstone to high temperatures to remove any brownish or yellowish hues and enhance the blue and violet colors that tanzanite is prized for. This treatment is considered stable and permanent.

This treatment can intensify or alter the color of tanzanite. Irradiated tanzanite may display a more vivid blue or purplish-blue color. Irradiation is usually followed by a heat treatment to stabilize the color changes.

Care instructions
