Natural Tanzanite

Natural Tanzanite Tanzanite exhibits a remarkable range of hues between lilac and blue. Blue violet coloration is the most prevalent.

Tanzanite values increase with the saturation of the color, and the deep blue and deep violet blue stones are the most treasured.

Tanzanite is somewhat more delicate than many gemstones and jewelry settings exposing the stone to frequent impact should be avoided. Tanzanite is strongly trichroic, and may present different coloration when viewed from differing angles.

There are 45 Tanzanite(s) organised in the following categories: Facet LotFacet SingleSet and Layouts,  gemstones. Price of our Tanzanite range from USD 22.00 to USD 371.00 and all gemstones are 100% natural. No lab, created or synthetic gemstones.

We grade our stones with strict adherence to current GIA (Gemological Institute of America) standards for color, tone, hue, saturation and clarity and all gems are identified and graded only by GIA certified gemologists.
