We drove to the Calcite Mine Trail, the site of the only operating calcite mine in the U.S., put into emergency operation after the attack on Pearl Harbor. The trail starts out just off the main, paved road and follows the old service road to the mine for the first few miles. At one point, though, the road dropped to the canyon floor, where a ...

Vibrant pink (cobaltoan) calcite price starts from $50 and reaches thousands of dollars. Colorless optical calcite (Iceland Spar) price is $30 to 500. Blue and green calcite price is about $20- 200. Orange and yellow calcite prices are about $10 to 100. The brighter the color, the more expensive the calcite is.

Calcites' colors include white, clear, gray, yellow, green, blue, brown, and black. Some calcite will fluoresce under both short-wave and long-wave UV light. Calcite may be found in caves as stalactites or stalagmites. Calcite and aragonite are polymorphs as they have the same chemical composition (CaCO3) but have different crystal structures.

Calcite's Specific Gravity: 2.7102 . As helpful as specific gravity is for identifying minerals, amateurs are usually constrained by the need for more necessary tools for the job. However, one way to work around this is to hold the specimen and note how heavy or hefty it feels compared to what you might expect a specimen of that size to weigh.

It has a specific gravity of 2.71. Three perfect cleavages give calcite its six-sided polyhedrons with diamond-shaped faces; the angles defining the faces are 78° and 102°. The three important crystal habits (distinctive shapes of the mineral) of calcite are: (1) prismatic (both short and long), (2) rhombohedral, and (3) scalenohedral.
