Sang-e-Seemaq: Garnet Gemstones

Garnet is not one mineral but a group of closely related silicates. Pyrope and almandine give the familiar deep red to wine and purplish red. Spessartine glows orange, rhodolite is raspberry pink, and tsavorite and demantoid are rare, bright greens. Local sellers use the name Sang-e-Seemaq, and in English the word garnet comes from pomegranate, after the red seeds.

Pakistan and Afghanistan both produce garnets, and the mountains of the north have yielded fine spessartine and almandine crystals. As with all gems, we only describe origin where we know it.

Choosing a garnet

Red garnet can look very dark, almost black, in a large stone. The best reds keep brightness and show a clear wine colour under ordinary room light, not just in sunshine. Medium sizes and shallower cuts help. In orange and green garnets, saturation and clarity drive price, and vivid stones above 2 carats are scarce.

Garnet is almost never treated, which is part of its appeal. Glass imitations and synthetic stones exist, and red glass with bubbles is the commonest substitute. Each listing names the garnet type and the treatment status we know.

Garnet has no fixed place in the nine-gem tradition, though some astrologers suggest hessonite garnet, called Gomed, for Rahu. Many people simply choose red garnet as a warm, affordable alternative to ruby, or as the January birthstone.

At 7 to 7.5 on the hardness scale and with no cleavage, garnet is well suited to daily rings. Open claws show off its brightness. Soap and warm water clean it well.
