White Rhombic Calcite

White rhombic calcite, also known as Iceland spar, is a fascinating mineral with unique visual properties. Here is a description of white rhombic calcite: White rhombic calcite appears as transparent to translucent crystals with a vitreous or glassy luster. Its crystal structure is characterized by distinct rhombus-shaped crystals, formed by intersecting cleavage directions at perfect right angles. These rhombus-shaped crystals can range in size, from small fragments to larger, more substantial specimens. The color of white rhombic calcite is typically colorless or milky white, allowing light to pass through the crystal and exhibit its remarkable optical properties. One of the most intriguing features of white rhombic calcite is its property of double refraction, also known as birefringence. When light enters the crystal, it splits into two rays, each following a different path. As a result, when viewed through the crystal, objects may appear doubled or distorted.
