Everything you loved about Blood Quartz is magnified in the A-Grade version of the material. The quality and transparency of the Quartz almost makes the red spots (caused by iron and hematite) look suspended in time.
Blood Quartz is a clear to milky to white silicon dioxide mineral. Its inclusions of red, orange and rust are due to traces of hematite within the stone. Quartz has been highly valued by virtually every civilization throughout history, often used in healing and meditation and as religious objects in funerary rites and to dispel evil.
