Loose Precious Gemstones

Ruby, sapphire and emerald, together with diamond, are the traditional precious gemstones, valued for their color, rarity and durability. This collection brings them together in loose form, both natural and lab-created, for jewelers, designers and collectors: calibrated millimeter sizes for matched work and one-of-a-kind single stones. Use the Natural / Lab-created switch to see one or the other.

Shop by gem: ruby, sapphire, emerald, or natural diamonds. Lab-created only: lab-created gemstones. For aquamarine, tanzanite, topaz and more, see semi-precious gemstones.
