Buying natural garnet: what to look for

Garnet is not one stone but a family. The red garnets you see here are mostly almandine and pyrope — the classic deep wine red — with occasional rhodolite (raspberry-purple). Green tsavorite and orange spessartine also exist but are much rarer.

  • Colour — the best red garnet is a saturated red that still shows light through it. Very dark stones look black in a ring; medium-dark stones look richer.
  • Clarity — cut garnet is usually eye-clean; rough crystals show natural faces and small pits, which is normal.
  • Weight and size — garnet is dense, so a 1-carat garnet is smaller than a 1-carat topaz. We list millimetre sizes so you can plan a setting.
  • Treatment — garnet is one of the few gems that is almost never treated. Ours are untreated unless stated.

Rough red garnet

Most of our stock is rough: dodecahedral crystals with their natural 12-sided shape, formed deep in metamorphic rock under heat and pressure. We explain the geology in how rough red garnet stones are formed. Rough garnet is popular for collections, crystal work and for cutting — a clean crystal of 5 carats can yield a 2-carat faceted stone.

Garnet as the January birthstone

Garnet is the birthstone for January in every list, old and modern, and the traditional second-anniversary gift. It is one of the easiest birthstones to buy well: natural, untreated and affordable even in larger sizes. See the full list on our birthstones page.

Garnet in jewellery

At 6.5–7.5 on the Mohs scale, garnet suits pendants, earrings and rings worn with a little care. A bezel or halo setting protects the edges. We make custom jewellery around any stone you choose here.

Care

Warm soapy water and a soft brush are all garnet needs. Avoid sudden temperature changes and steam cleaners. Store it away from harder stones (sapphire, topaz) that can scratch it.
