Physical properties
Polished, opaque green beads with dark red-brown patches and a vitreous to waxy luster. Quartz hardness is about 6.5–7 Mohs; jasper is microcrystalline and has no visible cleavage. Beadwork and lighting limit reliable identification.
Formation & geological history
Jasper forms when silica-rich fluids fill cavities or replace rock, with iron-bearing minerals producing its colors. The trade name is often associated with material from Western Australia, but bead appearance alone cannot establish the source or age.
Uses & applications
Used for beads, cabochons, ornaments, and inexpensive jewelry.
Geological facts
“Dragon blood jasper” is a commercial name, not a formal mineral species; similarly patterned stones may be sold under other jasper or trade names.
Field identification & locations
Check for opaque, mottled color and a glass-scratching hardness; confirm identity with a gemologist, since dyed or other green-and-red stones can look similar. Comparable bead strands commonly sell for about $10–$50 USD, depending on size and workmanship.
