💎 About Tanzanite

Tanzanite is a rare and precious gemstone found only in one place on Earth: the Mererani Hills near Arusha, in northern Tanzania. It was discovered in 1967 and named after Tanzania, its country of origin.

Tanzanite is a variety of the mineral zoisite and is prized for its stunning blue to violet hues, which can shift depending on the angle of light — a feature known as pleochroism.

Today, Tanzanite is considered 1,000 times rarer than diamonds and is one of the most sought-after colored gemstones in the world.
