Lense strand, Hypersthene, 21 x 14mm

The flat Lenses are approx. 21mm long, 14mm wide and 6mm thick; the entire strand has a length of approx. 40cm.

Hypersthene got its name from the Greek "hyper" (over) and "stheos" (strength); this refers to the greater hardness compared to the closely related Bronzite. Spellings such as hyperstene or hyperstehne are therefore incorrect.

In 1988, Hypersthene was renamed Ferrosilite by the International Mineralogical Association. Synonyms for Hypersthene are Augite-Bronzite, Iron Anthophyllite, Iron Enstatite, Ferroanthophyllite, Ficinite, Labradorblende, Paulite, Schiller Spar and Szaboite as well as Hyperstein.
