Calcite Calcite is a very common mineral. It is found in most places on earth. It is a sedimentary mineral. Calcite crystals come in many different shapes. There are more than 300 different crystal shapes. This is more than any other mineral. People who decide to collect only calcite can have a very interesting collection because there are so many shapes that calcite comes in. One common use for calcite is that it is used in making cement.

Calcite Rhomb This calcite specimen still looks like a rhomb (squished box) but its edges are rounded. Its surface is also like satin and looks pearly. Calcite breaks into rhombs very easily, especially when exposed to the weather. This piece has been tumbled with other pieces of calcite as it tumbled down the mountain side. it is also fluorescent perfect cleavage smooth flat breaks white streak	SPECIMEN: CALCITE Rhomb SPECIMEN ORIGIN: North Bay, Ontario, CANADA
Weathered Calcite This piece of pink calcite was buried under a thick layer of forest soil. As the water moved along the rock, it eroded it. That is why the calcite is criss-crossed with fine sharp lines and is a darker color. The part of the calcite that was freshly broken or cut, is still a fresh pink color.
