Honey Calcite
Calcite (Calcium Carbonate) · Mineral Specimen / Decorative Stone
Crystal System
Trigonal; this specimen exhibits a massive, rhombohedral crystal habit with visible cleavage planes.
Mineral Group
Carbonates (Calcite group)
Chemical Formula
CaCO3
Formation Process
Sedimentary/Hydrothermal; formed through chemical precipitation in cave environments or hydrothermal veins.
About This Crystal
Translucent to semi-opaque specimen with a golden-yellow to honey-brown coloration. It features a waxy to vitreous luster with distinct rhombohedral cleavage steps visible on the surface.
Physical Characteristics
Color: Honey yellow; Streak: White; Cleavage: Perfect rhombohedral in 3 directions; Specific Gravity: 2.71; Fluorescence: Often fluoresces pink or blue under UV light.
Optical Properties
Uniaxial negative; Refractive Index: 1.486–1.658; Extreme birefringence; Double refraction (doubling effect) may be visible in clear sections.
Hardness & Durability
Origin Region
Mexico (most common source for honey-colored varieties), USA, and Brazil; forms in sedimentary limestone environments.
Hardness & Durability
Mohs Hardness: 3 (soft); Toughness: Low/Brittle; Highly sensitive to acids and easy to scratch.
Care & Maintenance
Avoid all acids (including vinegar/citrus), ultrasonic cleaners, and steam. Clean only with warm soapy water and a soft cloth. Store separately to prevent scratching from harder minerals like quartz.
Rarity & Value
Common; Value is generally low, based on color saturation and clarity. Most specimens are sold by weight as cabinet pieces.
Special Characteristics
Features strong double refraction and can exhibit rhombohedral 'step' growth patterns. Some specimens show phosphorescence after exposure to UV light.
Lore & History
Historically used as a source of lime. In lore, it is associated with the solar plexus and sacral chakras; believed to enhance willpower, self-worth, and mental clarity.
