Honey Calcite
Calcite (variety Honey) · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Trigonal; typically occurs in rhombohedral or scalenohedral forms, though this specimen is polished into a palm stone.
Mineral Group
Carbonates
Chemical Formula
CaCO3 (Calcium Carbonate)
Formation Process
Sedimentary or Hydrothermal; forms through chemical precipitation in marine environments or from calcium-rich hot springs and groundwater.
About This Crystal
A translucent to transparent golden-yellow to deep honey-brown crystal. This specimen shows a vitreous to waxy luster with visible internal rhombohedral cleavage planes and a 'honeycomb' internal structure.
Physical Characteristics
Color: Golden-yellow; Streak: White; Cleavage: Perfect rhombohedral in three directions; Fracture: Conchoidal (rarely seen due to cleavage); Specific Gravity: 2.71; Fluorescence: Often fluoresces pink or blue under UV light.
Optical Properties
Refractive Index: 1.486–1.658; Birefringence: Extremely high (0.172), often causing double refraction where text appears doubled through the crystal.
Hardness & Durability
Origin Region
Notably Mexico, Brazil, and the USA; forms in sedimentary environments and hydrothermal veins.
Hardness & Durability
Mohs Hardness: 3.0. It is a soft stone, prone to scratching and easy breakage along cleavage planes; low durability for jewelry.
Care & Maintenance
Clean only with warm soapy water; avoid ultrasonic cleaners and acids (vinegar will dissolve it). Store away from harder stones like quartz to prevent scratches.
Rarity & Value
Common; value is determined by transparency and color saturation. Generally affordable, widely used for decorative items and palm stones.
Special Characteristics
Strong double refraction (calcite-style) and distinct rhombohedral internal fractures are visible in this specific polished piece.
Lore & History
Historically used as a source of lime. In metaphysical lore, it is associated with the Solar Plexus and Sacral chakras, believed to enhance personal power and confidence.
