Pink Calcite
Calcite (Manganese-bearing variety) · Mineral Specimen
Crystal System
Trigonal, rhombohedral habit forming druzy and massive clusters
Mineral Group
Carbonates
Chemical Formula
CaCO3
Formation Process
Hydrothermal and sedimentary deposition in low-temperature aqueous environments
About This Crystal
A cluster of pale pink to peach-colored rhombohedral calcite crystals on a matrix base, displaying a vitreous to pearly luster and translucent transparency
Physical Characteristics
Pink to white color, white streak, perfect rhombohedral cleavage in three directions, conchoidal fracture, specific gravity around 2.71, brittle tenacity, strong pink-orange fluorescence under shortwave UV light
Optical Properties
Uniaxial negative with strong birefringence and double refraction
Hardness & Durability
Origin Region
Found globally with notable deposits in Mexico, Peru, and Madagascar
Hardness & Durability
Mohs hardness of 3, poor toughness due to perfect cleavage, sensitive to acids and scratching, unsuitable for daily-wear jewelry
Care & Maintenance
Clean with mild soap and warm water, avoid all acids including household vinegar, store separately to prevent scratching, avoid prolonged direct sunlight
Rarity & Value
Common, widely available as mineral specimens with prices ranging affordably based on crystal size and color saturation
Special Characteristics
Strong pink fluorescence under ultraviolet light and pronounced double refraction
Lore & History
Often associated in modern crystal healing with the heart chakra, emotional healing, and gentle calming energies, though these are traditional beliefs without scientific backing
