Hematite has been shaped into chevron beads and plated an irridescent shimmering rainbow. A chevron is an ancient symbol that appears in a wide variety of settings including flags, pottery and architecture. In Celtic symbolism the shape marks a warrior, hunter or builder. More generally, the chevron represents dutiful service given freely.
This hematite is polished oxide of iron. It is said to have a positive effect on the bloodstream and increase resistance to stress.
