Physical properties
Hardness of 5.5 to 6.5 on the Mohs scale, pink to pale rose color with occasional translucent crystalline quartz matrix, waxy to vitreous luster, amorphous crystal structure with no cleavage, and a specific gravity around 2.1.
Formation & geological history
Forms at low temperatures from silica-rich water solutions depositing in cavities of volcanic rocks or sedimentary strata, typically occurring in arid environments.
Uses & applications
Used primarily for ornamental carvings, polished cabochons in jewelry, and metaphysical crystal healing collections.
Geological facts
Pink opal is often found naturally associated with clear crystalline quartz and dendritic manganese inclusions, creating striking visual contrasts.
Field identification & locations
Identify by its distinct soft pink coloration, lack of cleavage, and waxy luster; major deposits are found in Peru, Australia, and Mexico.
