Mandarin Garnet Value

Mandarin garnet is unequivocally orange, but its exact definition can vary. "Mandarin garnet" has been used as a trade name for vivid orange spessartite garnets from Namibia as well as a trade name for all spessartite garnets that possess that color. In the mid 1990s, the only garnets that fit either description were from Namibia. Like other garnets, these gemstones were mixed species. Their average composition was 85 mol.% spessartite, 12.5 mol.% pyrope garnet, and 2.5 mol.% grossular garnet. The high manganese (Mn) content of spessartite gave them their striking orange color.
In 1998, Nigeria began producing gem-quality spessartite (95 mol.%) with an orange color that approaches that of the Namibian material. In 2007, gem-quality orange spessartite was discovered in Tanzania with a composition very close to the Namibian stones: 77.5 mol.% spessartite, 17.9 mol.% pyrope, and 4.6 mol.% grossular.
Whether defined by color, source, or chemical composition, Mandarin garnets made a splash in the jewelry world. Spessartite garnets are rare, and facetable material rarer still. The discovery of these gem-quality African gemstones meant jewelers and consumers could explore and enjoy the brilliance of these garnets.
These gemstones don't normally receive any treatments or enhancements, thus making them very desirable to collectors and enthusiasts of natural gems.

Mandarin garnets greater than 10 carats are extremely rare. At the Tucson Gem and Mineral Show in 1995, Colgem displayed a faceted, cushion-shaped 29.77-ct stone and an eye-clean triangular mix-cut 14.77-ct stone. The Houston Museum of Natural Science has a gold ring with a faceted 39.35-ct mandarin garnet on display.
When first discovered, mandarin garnets received trade names such as "hollandines" and "Kunene spessartines."
