Pietersite is the trade name for a breccia-like mixture of hawk's eye and tiger's eye in colors ranging from dark blue-gray to brown-yellow, and thus by definition a rock.

Pietersite was discovered in 1962 by Sidney “Sid” Pieters in Southwest Africa (now Namibia), and the stone is named after him. The exact find site is given as Hopewell Farm, about 40 km northeast of the town of Outjo in the Kunene region. The only other known find site (as of 2017) is Nanyang in Henan Province, China, where Pietersite was discovered in 1993.

Pietersite is used exclusively as a gemstone and is offered in cabochon or table-cut and processed into artisanal items.

According to other sources, Pietersite is described as a variety of chalcedony with fibrous inclusions of amphibole minerals. Hawk's eye and tiger's eye are, however, microcrystalline varieties of quartz, like chalcedony, and thus contain the same basic substance, and the crocidolite- or hornblende-fibers interwoven in tiger's eye and hawk's eye belong to the amphibole group.
