Sale price$15,621.00 NZD
In stock

An exceptional 13.18 carat natural oval-cut tanzanite gemstone displaying superb blue-dominant royal-blue colour with beautiful violet flashes.

The accompanying GIA Identification Report confirms this tanzanite as blue dominant, while its exceptional colour saturation, clarity and overall appearance place it within our AAA+ / Heirloom / Investment Grade quality range.

Its rich royal-blue body colour is enlivened by flashes of violet as the stone moves, while flawless clarity and excellent transparency allow the precision of the oval faceting to shine brilliantly.

At over 13 carats, this is an impressive example of a fine large tanzanite gemstone. Tanzanites combining substantial size, exceptional clarity and strong blue-dominant colour are particularly sought after by collectors and clients looking for a significant loose gemstone or centre stone for an important piece of jewellery.

This gemstone is accompanied by a GIA Identification Report, providing independent confirmation of its identity and blue-dominant colour.

A superb choice for a collector, a significant bespoke ring or pendant, or anyone seeking a rare AAA+ investment-grade tanzanite with the additional confidence of GIA certification.
