Here is one rather long glassy crystal with a couple of short crystals intersecting across its face. The specimen shows some nice blue-green marbling. The back side is a flat face of cleavage. A nice sample from the Norland area.

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. Since we're unsure of the chemical difference we will use tremolite to identify these crystals. Tremolite is not uncommon in this area, most often found in the form of dense inter-grown fibrous material, thus making these gemmy and highly lustrous crystals something special!
