Physical properties
Hardness: 3 on Mohs scale; Color: Cream, beige, with dark inclusions; Luster: Vitreous to waxy; Crystal structure: Trigonal/hexagonal (microcrystalline calcite); Cleavage: Perfect rhombohedral
Formation & geological history
Formed from the regional metamorphism of limestone or dolostone under high temperature and pressure, typically in mountainous regions. This specimen has been artificially carved and polished.
Uses & applications
Construction, decorative flooring, sculptures, tabletops, and metaphysical paperweights or decor pieces.
Geological facts
Marble has been used since ancient times for its ease of carving and beauty. The dark spots (speckles) in this specimen are likely mineral impurities like graphite or silicates trapped during metamorphism.
Field identification & locations
Identify by its relative softness (scratches with a metal blade) and strong reaction to dilute hydrochloric acid. It is commonly found in countries with metamorphic belts like Italy, Turkey, and China.
