Gorgeous, tanzanite, old mine material, violet - 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 - 7.15 carat
Measurements - 11 mm x 8.37 mm
Cut - Round, brilliant precision cut
Color - Top Vivid, Violet - Blue. Occasional red pinpoint flashes indicative of top material. 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 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.
