Zoisite (Var: Tanzanite)
Thumbnail, 2.3 x 0.9 x 0.8 cm
Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania
The two gemmy and lustrous, parallel-growth tanzanite crystals with sharp terminations exhibit classic, textbook pleochroism. The A and B axes are the beautiful, blue and blue-violet, while the C axis is a rich reddish-brown, nearly a clove-brown, indicative of natural unheated state of color (hard to photo). This is a fine, complete-all-around and pristine, untreated tanzanite thumbnail with textbook colors and sharp crystal form. Weighs 33.61 carats or over 6 grams.
