6.43 carats Natural Tanzanite Gemstone | Emerald Cut – 11.7 × 8.3 × 7.4 mm

This natural tanzanite from Tanzania displays an intense blue-violet color with exceptional brightness and saturation. The color is vivid and striking, presenting a highly attractive visual character that immediately draws attention at this size.

Cut in a classic emerald (step) cut, the gemstone emphasizes clarity, depth, and clean architectural lines. The broad step facets create strong flashes of light while maintaining excellent transparency, allowing the stone’s crystal-clear structure and rich color to remain the focus.

Weighing 6.43 carats and graded as **Heirloom quality**, this tanzanite is eye clean and visually pure. Its combination of size, clarity, and color makes it especially well suited for bespoke statement jewelry, including high-impact rings or pendants designed to be treasured long-term.

This gemstone may be secured on its own, or crafted into a custom ring or fine jewelry piece through the SARATTI atelier.
