Here's a cluster of green tremolite featuring a singular gemmy and highly lustrous crytsal sitting at the top. The main crystal is terminated and shows wonderful interior light refraction!
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.
