Gorgeous, tanzanite, old mine material, blue-blue with hint of violet, occasional red flashes. Cushion cut with precision faceting. Old material, mined and cut over a decade ago in the D-Block mine. This is top tanzanite not overly dark and not washed out coloring of many modern tanzanite ( Zoisite ).
Gem Type - Tanzanite
Weight - 7.25 carat
Measurements - 13.92 mm x 11.02 mm x 7.36 mm
Cut - brilliant precision cut
Color - Multi Color, Ocean blue
Clarity - Flawless
Treatment - this could be an unheated piece based on color but if not it is - Methodical slow heating to top industry standards turning Zoisite into Tanzanite. This is one case where heating raises value of gemstone if done correctly.
This could qualify as geothermal heated material based on age but we simply don’t know for sure. So consider it heated but if you are lucky it may not be but we priced it as heated material.
Origin - Tanzania, D-Block mine
Notes - These older pieces of Tanzanite were procured when the mines were producing top material. Many later pieces were overly dark or washed out but this is a velvety blue with just the right amount of a violet hue. I assure you this is the Tanzanite quality both jewelers and collectors seek.
