Canasite Value, Price, and Jewelry Information
The material usually seen on the market as “canasite” is purplish in color. It is frequently confused with another purplish material, a member of the serpentine family known as stichtite. However, stichtite occurs in elongated fibers that have a kind of lustrous sheen, almost asbestiform, whereas canasite is granular. Recent research seems to indicate that, in fact, the material being called “canasite” has no canasite in it but is a new, distinct species.
