2.26ct Marquise Tanzanite


This is a 2.26ct marquise cut tanzanite.  This is an exceptionally clean stone with amazing blue color for its size. This stone would make a fabulous ring or small pendant. This stone was mined in Tanzania. 

Tanzanite is the blue variety of the mineral Zoisite, found the Merelani Hills near Arusha, Tanzania. Gem quality tanzanite has only been found in this remote location of East Africa. Tanzanite is a trichroic gemstone, meaning that it shows three colors down its different axis, making orienting the rough before cutting very important. Like tsavorite, tanzanite is a newly discovered gemstone, first found in the 1960s. Tiffany & Company recognized that this amazing blue stone would become an international seller and quickly became its main distributor. Tanzanites popularity has grown steadily ever since. Many Tanzanites are heat treated to produce colors ranging from a soft pale blue through to vibrant dark violetish blue and even blueish purple. Rich, deep hues are the most valued but it is rare to find those colors in stones less than 4cts.


Tanzanites are found in Northeast Tanzania.


Tanzanites measure about a 6 - 7 on Mohs hardness scale.

Refractive Index:

Tanzanites have a refractive index of about 1.69 - 1.77.

Care and Cleaning:

It is recommended to clean your tanzanites with warm, soapy water. Ultrasonic and steam cleaning should never be used on a tanzanite. Due to its hardness and cleavage, special care will need to be given to tanzanite jewelry that is worn daily.
