Also called heliotrope, bloodstone is a dark green chalcedony scattered with vivid red flecks of iron-oxide jasper, a pattern early observers likened to drops of blood on a green field. It belongs to the trigonal quartz group and measures 6.5 to 7.0 on the Mohs scale, durable enough for rings and carved seals. Used since antiquity for signets and talismans, it was linked in ancient Rome and medieval Europe with warriors and healing, and was once believed capable of staunching bleeding. The finest material comes from India, particularly the Kathiawar Peninsula of Gujarat. A moderately priced semi-precious stone, bloodstone is a traditional birthstone for March.

About Bloodstone (Heliotrope)

A heliotrope, ou pedra de sangue, é uma variedade de calcedónia verde-escura salpicada de manchas vermelhas de jaspe, que evocam gotas de sangue. Esta aparência particular conferiu-lhe uma forte simbologia ao longo da história: era considerada sagrada pelos primeiros cristãos, que a associavam ao sangue de Cristo derramado na crucificação. Era muito utilizada em selos e amuletos na Antiguidade e na Idade Média. Actualmente é utilizada em joalharia clássica para intaglios, cabeções de anel e pendentes. É encontrada principalmente na Índia, Austrália, Brasil e China.
