Honey Calcite
Calcite var. Honey Calcite · Collector Mineral / Decorative Stone
Crystal System
Trigonal; typically occurs in massive, rhombohedral, or scalenohedral forms
Mineral Group
Carbonates (Calcite Group)
Chemical Formula
CaCO3 (Calcium Carbonate) with possible Iron or Sulfur inclusions
Formation Process
Sedimentary/Hydrothermal; forms via chemical precipitation in sea water or groundwater, often in caves or hot springs
About This Crystal
A translucent to semi-opaque specimen with a warm, golden-yellow to amber-honey hue. It exhibits a waxy to vitreous luster and distinct internal banding or 'growth rings' visible in the tumbled form.
Physical Characteristics
Color: Honey yellow; Streak: White; Cleavage: Perfect rhombohedral in 3 directions; Fracture: Conchoidal; Specific Gravity: 2.71; Fluorescence: Often exhibits salmon pink or blue under UV light
Optical Properties
Refractive Index: 1.486 - 1.658; Birefringence: Extremely high (0.172); Optically Uniaxial (-); No significant pleochroism
Hardness & Durability
Origin Region
Mexico, USA (Utah), Madagascar, and Brazil; found in sedimentary limestone and marble environments
Hardness & Durability
Mohs Hardness: 3.0 (Soft); Toughness: Poor due to perfect cleavage; Low durability, susceptible to scratches and acid
Care & Maintenance
Clean only with warm soapy water; avoid ultrasonic and steam cleaners. Keep away from acids (vinegar/lemon juice) which will dissolve the stone. Store separately to prevent scratching.
Rarity & Value
Common; Value is generally low to moderate. Most valued for saturation of color and clarity. Common treatments: None (usually natural color).
Special Characteristics
Displays strong double refraction (iceland spar effect) if transparent; often shows prominent parallel banding layers in tumbled specimens.
Lore & History
Historically used in various cultures as a stone for confidence and persistence. In metaphysical lore, it is associated with the Solar Plexus and Sacral chakras, believed to enhance mental clarity and personal power.
