| Key Feature |
Hematite is an iron oxide mineral with a distinctive metallic lustre that makes it immediately recognisable. Notably heavy for its size due to its high iron content, hematite has been used since ancient times — cave painters used red ochre (powdered hematite) 40,000 years ago. In crystal healing, hematite is the ultimate grounding stone, pulling scattered energy down through the Root chakra into the earth. Its reflective surface is believed to deflect negative energy like a mirror.

Black onyx is a variety of chalcedony (microcrystalline quartz) prized for its deep, uniform black colour and smooth, lustrous finish. Roman soldiers carried onyx into battle for courage and protection, and it has been carved into cameos and protective amulets for millennia. Working through the Root chakra, black onyx builds inner strength, self-discipline, and emotional resilience. It is particularly valued for supporting those going through grief, trauma, or demanding life circumstances.
