Calcite var. Caribbean Calcite · Decorative Stone and Mineral Specimen
Crystal System
Trigonal, custom-carved and polished into a towering prismatic obelisk habit.

Formation Process
Sedimentary or low-temperature hydrothermal precipitation, often forming in association with aragonite in cavities or veins.
About This Crystal
A large hand-carved tower featuring soothing pastel blue, seafoam green, and earthy brown or white banding. It displays opaque to translucent layers, a waxy to vitreous luster on polished surfaces, and rough natural matrix inclusions running vertically along one side.
Physical Characteristics
Color includes soft blue, white, and tan-brown. Streak is white. Perfect rhombohedral cleavage in three directions (not visible on this carved piece). Conchoidal to uneven fracture. Specific gravity is approximately 2.71. Brittle tenacity. Exhibits strong effervescence in dilute hydrochloric acid.
Optical Properties
Uniaxial negative with high birefringence, producing noticeable double refraction in transparent varieties, though this specimen is largely opaque and banded.
Hardness & Durability
Origin Region
Primarily sourced from Pakistan, recently discovered and popularized for its unique pastel oceanic color banding.
Hardness & Durability
Mohs hardness of 3. Low durability and poor wearability for rings or bracelets due to softness and perfect cleavage. Easily scratched by a copper coin or knife.
Care & Maintenance
Extremely sensitive to acidic household cleaners, vinegar, and lemon juice due to calcium carbonate composition. Clean only with a soft damp cloth. Avoid harsh chemicals, prolonged water immersion, and direct sunlight.
Rarity & Value
Uncommon to rare due to its limited geographical discovery in Pakistan and high demand by collectors for its unique aesthetic. Valued based on size, pattern definition, and color saturation.
Special Characteristics
Combines soft blue calcite with contrasting earthy brown and white aragonite matrix, often showing interesting vugs and natural cavities within the carved tower structure.
Lore & History
A recently discovered mineral combination often used in modern crystal healing practices to promote inner peace, emotional healing, and deep relaxation. Associated with the third eye and crown chakras in contemporary crystal lore.
