A lapidary (or lapidarist) is an artist or artisan who forms stone, mineral, gemstones into decorative items such as engraved gems, including cameos, or cabochons, and faceted designs, or who is an expert in precious stones; and can be a collector of or dealer in gems. Diamond cutters are generally not referred to as lapidaries, due to the specialized techniques which are required to work diamond.
