Kuranze Tsavorite is a Tsavorite deposit world renowned for it's spectacular color. This deposit is in the area where Tsavorite was first discovered, near the famous Tsavo game reserve in Kenya (from which it's name derives). It contains more chromium than most other mines and the result is a truly spectacular blue-green that would put the finest Muzo emerald to shame.

This extraordinary 6.74 carat Oval was mined in Kuranze in 1993 and has remained in our Legacy Collection since then. In honor of 50 years in the business, we are cutting some of the finest pieces in Legacy Collection year and this is truly extraordinary stone is one of those selected. The color is absolutely exceptional and the stone really glows with life and luster.

SPINEL STUNNER... Explosive Unheated 3.81 Carat Mahenge Red Spinel.

The discovery of intense red and pink spinels in the Mahenge District of Tanzania in 2007 hit the gem world by storm and thrust Spinel into the limelight. The first stone found was in a farmers field - workers found a giant Spinel crystal weighing 114 Pounds. This Mahenge Spinel crystal displayed the gorgeous vibrant pink and red color that is now famous from Mahenge Spinel. The crystal was full of inclusions and had to be “knocked” into smaller sized pieces. This began a love affair in the gem world with this incredibly rare and exciting stone, thrusting Spinel center stage. Most of the Mahenge deposit is mined out now but occasionally some nice pieces are found such as this one.

This fine oval has gorgeous sparkle and the coveted vivid intense red hue inherent to this deposit. It has not undergone any form of treatment, including thermal (heat) treatment and is entirely natural. Very beautiful and very rare.
