Physical properties
Hardness 5.5-6.5. Metallic luster. High specific gravity. Often iridescent coating applied.
Formation & geological history
Natural hematite forms in sedimentary environments or hot springs. Rainbow beads are typically synthetic magnetic hematite coated with titanium or other metals.
Uses & applications
Commonly used in inexpensive jewelry, beads, and 'magnetic therapy' items.
Geological facts
True rainbow hematite occurs naturally but is rare; most beaded jewelry is synthetic and artificially coated to produce the iridescent effect.
Field identification & locations
Identified by heavy weight, strong magnetic pull (if synthetic magnetic hematite), and iridescent metallic sheen.
