8.56 carats Natural Blue-purple Tanzanite oval cabochon main view | SARATTI

Description

This Natural Blue-purple Tanzanite presents a saturated blue-purple body colour with a strong blue presence and subtle violet undertones. As the cabochon moves in the light, gentle directional variation between blue and purple becomes visible, giving the stone a softly pleochroic appearance. Face-up, it shows a rich and luminous impression with natural tonal variation beneath the polished dome.

Fashioned as an oval cabochon, the gemstone has a smooth, rounded dome and a continuous polished surface rather than faceted planes. The cabochon cut encourages broad, even light movement across the stone, favouring the blue body colour while allowing purple undertones to emerge at changing angles. Visible natural internal characteristics contribute to the layered depth seen within the stone.

Weighing 8.56 carats and measuring 13.3 × 10.2 mm, this Tanzanite has a substantial face-up presence within a balanced oval outline. Its smoothly domed profile would suit a pendant, brooch or earrings, and it may also be used in a carefully protected bespoke ring design. A bezel, halo or guarded setting would offer appropriate support for this cabochon gemstone.
