6.45 carats Natural Tanzanite Gemstone | Emerald Cut – 8.2 × 11.7

This natural tanzanite from Tanzania displays a vivid blue-violet color with strong saturation and lively brilliance. The hue is bright and well balanced, presenting the distinctive color profile that fine tanzanite is known for, especially in larger stones.

Cut in an emerald (step) cut, the gemstone emphasizes clarity, depth, and clean geometry. The step faceting creates broad, mirror-like flashes that highlight the stone’s transparency and color concentration, giving it a refined and elegant visual presence.

Weighing 6.45 carats, this tanzanite offers impressive scale and is graded as **Heirloom quality**, making it well suited for bespoke statement jewelry. Its eye-clean appearance and strong color make it ideal for high-end rings or pendants designed to be kept and passed down.
