High Quality Content by WIKIPEDIA articles! A lapidary (the word means "concerned with stones") is an artist or artisan who forms stone, mineral, gemstones, and other suitably durable materials (amber, shell, jet, pearl, copal, coral, horn and bone, glass and other synthetics) into decorative items such as engraved gems, including cameos, or cabochons, and faceted designs. Hardstone carving is the term in art history for the objects produced and the craft. Diamond cutters are generally not referred to as lapidaries, due to the specialized techniques which are required to work diamond. Gemcutter typically refers to diamond cutters or producers of faceted jewels in modern contexts, but artists producing engraved gems, jade carvings and the like in older historical contexts.
