TOP! Gorgeous, tanzanite, old mine material, Blue/Blue 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 the washed out coloring of many modern tanzanites NOR overly dark material overheated and NOT retreated so it isn’t black.
Gem Type - Tanzanite Thermalized Zoosite
Weight - 9.29 carat
Measurements - 13.2 x 10.7 mm
Cut - Cushion, precision brilliant faceting
Color - Top Vivid, Blue. Occasional red pinpoint flashes indicative of top material. Hint of violet. This is highly sought after material.
Clarity - Flawless
Treatment - Methodical slow heating to top industry standards turning Zoisite into Tanzanite. This is one case where heating raises value of a gemstone if done correctly.
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 violet- blue with just the right amount of a violet hue. I assure you this is the Tanzanite quality both jewelers and collectors seek.
