Icelandic Spar (also known as Calcite – Calcit – Calcite – Calcita ) Helgustaðir farther along the shore east of the village Eskifjörður, is worldfamous. Polarizing light with Iceland spar from here, the 17th century Dutchman Huygens published discoveries on light as a phenomenon of waves.
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.

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".
OPTICAL CALCITE DEPOSITS IN PARK AND SWEET GRASS COUNTIES, MONTANA By W. C. STOLL AND FRANK C. ARMSTRONG ABSTRACT The calcite deposits of Park and Sweet Grass Counties, Mont., although mined locally for chicken grits, had yielded only slightly more than 600 pounds of optical spar and mineral specimens before World War II.

Spar—Dogtooth and nailhead spar line bedrock or fill solution cavities in the walls, ceilings, and floors of Guadalupe caves. Dogtooth spar consists of scalenohedrons of calcite and nailhead spar is a more blunted form of calcite consisting of combined flat rhombohedrons and prisms which display unevensided triangular patterns.
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.

The transparent Iceland Spar variety, in which the double refraction is very apparent, was used as prisms for polarizing microscopes and other optical devices. Calcite also forms rocks that are used for ornamental purposes, such as marble and banded travertine or tufa. Calcite is also the main component of chalk, which is processed for drawing ...
