10.20-Carat Tanzanite – Exceptional Colour & Presence

This magnificent 10.20-carat tanzanite is a true collector’s stone. Expertly cut for maximum brilliance, it displays vibrant life and sparkle across every facet. Most impressively, its proportions give it substantial face-up measurements, allowing it to look closer to a 15-carat stone — an incredible visual impact for its actual weight.

The colour is very blue -  approximately 95%  a rich, saturated blue, with a hint of violet - togeather creating that coveted dual-hue play that only the finest tanzanite can offer. With flawless clarity  the colour glows cleanly throughout the gem, unobstructed by any inclusions.

Tanzanites over 10.00 carats of this calibre are increasingly rare, making this an extraordinary choice for a serious collector or anyone seeking a show-stopping centre stone.

A stunning investment-grade tanzanite with exceptional colour, life, and presence.
