Loose Tanzanite Suite- Nearly 4 carat set of three excellent quality natural tanzanite that display terrific dichroic color with great clarity, cut and polish. The deep blue hues shift to violet depending on the viewing angle and lighting. Most tanzanite that displays blue and purple color has been heated and there is no way to definitively test for heat treatment in this mineral, and there is no synthetic of this single-source gem, only simulants or substitutes!
