Origin

Tanzanite is found in the Mererani Hills of Manyara Region in Northern Tanzania.

History

Tanzanite was named after its country of origin by Tiffany & Co., the initial distributor of the stone. Tanzanite is a kaleidoscope of royal blue, violet, indigo, lilac, and periwinkle shades. The beauty of this gem has become a wildly known favorite amongst jewelry wearers and designers.

Fashion

Tanzanite's brilliant, bold colors make it a popular choice for statement pieces! Tanzanite rings are especially popular, and tanzanite engagement rings are becoming an increasingly appealing choice for anyone looking for a colorful, unique alternative to the classic diamond!

Formation

During increased techtonic plate activity in the Mozambique Ogeanic Belt, techtonic plates collided with intense pressure, effectively morphing the existing igneous rocks together. During this collision, the rocks reached such a high heat that they nearly melted, creating beautiful crystalline structures. These crystles are unique to the area they are created in, due to the unique combination of minerals present in the area, which is why Tanzanite is only found in one region of the world. This process is called regional metamorphism.

Tanzanite is a variety of the mineral zoisite.

Cleaning & Care

Clean tanzanite at home with warm, soapy water. Ultrasonic and steam cleaners are not recommended. Tanzanite should be kept out of heat and properly stored in a cloth-lined jewelry box to protect from scratches.

Treatments

Tanzanite is often treated with heat to reveal the beautiful rich coloring.
