Description: Pink calcite is a captivating variety of calcite renowned for its delicate pastel hues and distinctive banding patterns of rose pink and pale yellow.
The color of the pink bands is attributed to the presence of manganese oxide minerals. Manganese can substitute for calcium within the calcite crystal lattice, leading to the development of pink hues. The yellow bands in can be attributed to the presence of iron oxide minerals, particularly hematite. The iron oxide impurities may have been introduced into the calcite during its crystallization process, resulting in the formation of yellow bands.
Like many manganese-bearing calcites, some of the manganese rich pink bands of this calcite variety can fluoresce a bright red color when exposed to UV light. The intensity of the fluorescence varies depending on the ratio of manganese to iron in the calcite. Areas with little to no iron and high concentrations of manganese will have the brightest fluorescence, while iron-rich areas will fluoresce less brightly or not at all.
