3.22 Carat Cushion-Cut Natural Tanzanite

This specimen is a natural zoisite, commercially known as Tanzanite, weighing 3.22 carats. It features a rectangular cushion mixed-cut with dimensions of 9.96 x 7.82 x 4.85 mm. The gemstone exhibits a vivid, saturated blue-violet hue, which is highly characteristic of premium Tanzanite sourced from the Merelani Hills of Tanzania. Physically, the gem is held by metal tweezers, showcasing its transparency. Upon close inspection, natural internal inclusions are visible, which serve as diagnostic markers for its natural origin. The craftsmanship of the cut appears symmetrical, designed to maximize light return and color depth within the crown and pavilion facets. The stone lacks visible surface abrasions or chips, suggesting it is in excellent condition for a loose gemstone. While the treatment is not specified in the accompanying IGI report metadata, most Tanzanites undergo gentle heating to enhance their blue-violet tones. This piece represents a high-quality contemporary gemstone suitable for high-end jewelry settings.
