The name “garnet” is derived from the Latin “granatum” meaning “pomegranate” because the crystals resemble the fruit’s red color and seed-like form. Most people think of the garnet as a red gemstone, but in fact, it exists in all kinds of colors – such as black – as well as many shades of red and green. It can even be colorless. Garnet’s variety of colors comes from metals such as manganese, iron, calcium, and aluminum. Some varieties even contain mineral fibers that produce the illusion of a four- or six-rayed star within the stone. Green garnets are the most highly prized but are very rare. Emerald green and colorless stones are highly valued, followed by pure red garnets.
Garnets are commonly found as small pebbles in streams, where the igneous and metamorphic rocks that contain them have weathered away. They’re found in many places around the world, including North and South America, Australia, India, Asia, and Spain.
Ancient warriors believed that garnets brought victory. The Crusaders used them as protection against wounds and accidents during their journeys. In contrast, Asiatic warriors believed that glowing garnets, used as bullets, inflicted more severe wounds. In 1892, during hostilities on the Kashmir frontier, the Hanza tribesmen fired on British soldiers with garnet bullets, believing them to be more effective than lead bullets.
