This process, first reported by Erasmus Bartholinus in 1669, is called double refraction. The two rays of light are each plane polarized by the calcite such that the planes of polarization are mutually perpendicular. For normal incidence (a Snell's law angle of 0°), the two planes of polarization are also perpendicu- lar to the plane of ...

Gem-quality calcite is MUCH rarer, and significantly lovelier than its more ordinary family members. It's found in colorless, white, gray, yellow, pink, and green shades. Gem-quality calcite often appears translucent. Because it's so lovely, we are drawn to it as adornment. We recommend you wear and treat calcite with care because it is a 3 on ...

The pink and reddish purple cobaltocalcite specimens (246.3 and 361.0 g, respectively) are shown with some of the wafers cut from them. Cobaltocalcite is a pink to purple variety of calcite. The mineral is popular as a collector's item because of its striking purplish pink color, which is caused, as the name suggests, by the presence of cobalt.

Dolomite, on the other hand, has a more laid-back kind of luster. It usually has a pearly or matte finish, which is less flashy. If calcite is like a shiny glass window, then dolomite is more like a pearl or a smooth pebble. Its luster is softer and doesn't reflect light as brightly as calcite.
