Sarbossa

Sarbossa also goes by many other names: thomsonite, lintonite, comptonite, ozakite, eye stone, or fire rock. It is found in small nodules up to one inch (two and a half centimeter) diameter in cavities of rocks formed during volcanic eruptions. It is fibrous and therefore both tough and soft. It is usually grayish green in color but is sometimes beautifully colored with rings of pink, red, white, and green. A typical specimen has a base value of 10gp.
