Highly transparent calcite is called optical spar. Although calcite can form spectacular crystals, it is usually massive, occurring either as marble () or as limestone (). It is also found as fibers, nodules, stalactites, and earthy aggregates. Calcite specimens can occur in metamorphic deposits, igneous rocks, and hydrothermal veins.
An optically clear form of calcite, originally from Iceland, but may occur anywhere. Originally reported from Helgustadir Mine, Eskifjord, Iceland.
Calcite as Limestone and Marble. Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.

Calcite is transparent to opaque and may occasionally show phosphorescence or fluorescence. A transparent variety called Iceland spar is used for optical purposes. Acute scalenohedral crystals are sometimes referred to as "dogtooth spar" while the rhombohedral form is sometimes referred to as "nailhead spar".
Helgustadir calcite was soon in demand throughout Europe''s scientific community. While the Danish parliament under Frederick III gave its permission for calcite mining at Helgustadir, no largescale to recover Iceland spar effort was made for many two centiuries.

The deposit is a Mississippi Valley Type (MVT) carbonate–hosted leadzinc deposit. The mine was closed in 2002 due to failing metal prices and declining resources. Nanisivik had a population of 287 in 1996, but that had fallen to 77 in 2001, as the mine wound down, and is now zero.
