Peridot Beads Gemstone Beads Rings & Things

Peridot beads are known by many names, including bastard emerald, chrysolite, evening emerald, hawaiite, night emerald, and peridote. These pretty green semiprecious beads are cut from an olivine variety composed of magnesium iron silie. Peridot splits and bends the rays of light passing through it, giving it a velvety appearance and rich glow.

Abstract Harvard University

During the igneous activity, magmas were apparently erupted from only one vent area, but changed in chemical composition from "hawaiite" (transitional to continental tholeiite) to true hawaiite and then to basanite. The basanite is the probable source of gemquality zircon and sapphire mined from placer deposits associated with the basalts.
