A pairing of two slender tremolite prisms showing a lustrous and gemmy green-blue colouration. The top is not terminated but is a plane of cleavage. Pretty nice lil guy!
Tremolite from the area is often dubbed "actinolite". Tremolite and actinolite are two very similar minerals that form a series with each other and essentially share the same chemical formula. Tremolite has a greater presence of magnesium over iron, whereas actinolite has a greater presence of iron over magnesium. Analyses have shown that actinolite is very rare and most specimens like this are tremolite. These gemmy and highly lustrous crystals something special!
