3.22 Carat Natural Tanzanite (Zoisite) Loose Gemstone

This specimen is a natural zoisite, commercially known as Tanzanite, weighing 3.22 carats. The gemstone is expertly cut into a rectangular cushion shape with a mixed cutting style, measuring 9.96 x 7.82 x 4.85 mm. It displays a vibrant, saturated blue-violet hue characteristic of high-quality Tanzanite, exhibiting strong pleochroism which is visible as the stone shifts under light. The crown features a well-defined table and symmetrical facets, though the internal clarity reveals significant natural inclusions. These inclusions include visible veining, fluid-filled feathers, and internal fractures that disrupt the light path, creating a somewhat 'sleepy' or fragmented internal appearance rather than eye-clean transparency. There is a notable internal reaching inclusion or surface-breaking fissure near the center, which may affect durability if set. The girdle thickness appears consistent, held here by laboratory tweezers for inspection. The color saturation is deep, suggesting professional heat treatment which is standard for the industry to achieve this specific blue-violet balance, though it remains listed as unspecified. The overall craftsmanship of the cut is good, aimed at maximizing weight retention while maintaining a classic cushion silhouette.
