Garnet

Garnet has been treasured as a gemstone for more than 5,000 years. Ancient Egyptian pharaohs wore garnet necklaces, and garnet beads were discovered in the tomb of Tutankhamun [Kunz, G.F., 1913. The Curious Lore of Precious Stones. J.B. Lippincott]. The name derives from the Latin granatum, meaning pomegranate seed, a reference to the stone's resemblance to the fruit's jewel-like red seeds [GIA Gem Encyclopedia, gia.edu]. In medieval Europe, garnets adorned sword hilts and armour — warriors believed the stone protected them in battle and guided them safely home. The Bohemian garnet mines of what is now the Czech Republic supplied most of Europe's garnets from the 15th to 19th centuries, with distinctive pyrope garnets becoming a symbol of Bohemian culture.

In Greek mythology, the pomegranate — which garnet visually echoes — was the fruit that bound Persephone to the underworld for part of each year, connecting garnet to cycles of loss, return, and loyalty. Norse mythology held that garnets were the embers of divine fires. In Islamic tradition, the Fourth Heaven is said to be illuminated by garnets [Kunz, G.F., 1913]. Medieval Christian artists used garnet to represent the blood of Christ in religious paintings and illuminated manuscripts, deepening its association with sacrifice, loyalty, and devotion.

Garnet is not a single mineral but a silicate group sharing the same cubic crystal structure while varying in chemical composition. Common varieties include pyrope (deep red), almandine (red-brown), spessartine (orange-red), grossular (green to orange), andradite (yellow-black), and uvarovite (emerald green). Most form in metamorphic rocks — particularly mica schist and gneiss — under high temperature and pressure conditions. The colour comes from trace elements: iron produces red, manganese creates orange, and chromium yields green. [Source: Mindat.org mineralogy database; GIA, gia.edu]
