A gemstone is generally known as the cut and/or polished form of a mineral. All gemstones are not minerals, however, as gemstone status has been given to some organic materials (pearls, ivory, amber) and some rocks (lapis lazuli). Qualities that determine a stone's gemstone status are rarity, beauty, and durability. Gemstones can be faceted, polished cabochons, or left in their natural form. Gemstones are also sometimes referred to as gems, precious or semi-precious stones, crystals, and jewels. For use in jewelry making, gemstones can be drilled completely (as beads), drilled partially to be post-set (like pearls on a ring or earrings), or left undrilled and set in prongs or bezels.
