This seftonite sphere has a distinctive, almost 'equal sign' pattern in bold, blood red jasper on one face of the piece together with mossy green colour throughout, semi-translucent, smoky grey patches and tiny flecks of metallic pyrite. It has been expertly polished to a high luster and shaped to a perfect, smooth ball. A wooden stand as pictured will be provided with this sphere.
Seftonite, also commonly known as 'African bloodstone' and less so as 'heliotrope', is a variety of chalcedony usually found as dark, moss green or grey semi-translucent masses with inclusions of blood red jasper, hence its common trade name, and may also include pyrite flecks. It is prized as an ornamental gemstone and for use in jewellery for its dramatic, contrasting colours and brecciated patterns.
