About This Crystal
A small carved figurine of an animal, likely an alpaca or llama, made from pale yellow calcite with milky white banding and patches. It has a waxy to vitreous luster and is translucent to opaque.
Physical Characteristics
Color is pale yellow to cream with white bands; streak is white; perfect rhombohedral cleavage in three directions; conchoidal fracture; specific gravity is approximately 2.71; brittle tenacity; effervesces in dilute hydrochloric acid
Optical Properties
Uniaxial negative with strong birefringence, resulting in a distinct double refraction visible through clear specimens
Hardness & Durability
Origin Region
Globally distributed; notable sources include Mexico, Peru, and the USA
Hardness & Durability
Mohs hardness of 3; low durability; very soft and scratches easily; sensitive to acids; poor wearability for daily-wear jewelry
Care & Maintenance
Clean with a soft damp cloth; avoid harsh chemicals, acids, and ultrasonic cleaners; store separately to prevent scratching by harder minerals; keep away from prolonged direct sunlight
Rarity & Value
Common; value depends on the quality of the carving, size, and translucency, generally very affordable
Special Characteristics
Exhibits strong birefringence and effervescence with acid; often features natural banding patterns
Lore & History
Historically associated with cleansing energy and clarity of mind; widely used in modern crystal healing for the solar plexus chakra to boost confidence and motivation, though these are traditional beliefs rather than scientific claims
