What is the color of a pink mangano calcite? As the photos show, it very much depends on the passing light. In a normal daylight it's gently pink, under the desk lamp the pink becomes more distinctive, under the UV light it glows bright pink and under the flashlight it appears yellow. This stunning big mineral heart is made of a so called Smoky Mangano Calcite, which means that it has a little bit of a gray (smoky) inclusions. It makes it look even more attractive, especially under the UV light. What do you think?
