Physical properties

Hardness: 3 on Mohs scale; Color: Soft pink to white; Luster: Vitreous to waxy; Structure: Granular/Saccharoidal; Cleavage: Perfect rhombohedral (in mineral form); Specific Gravity: 2.7

Formation & geological history

Formed through the regional metamorphism of limestone. Under high heat and pressure, calcite grains recrystallize into a dense, interlocking mosaic of crystals. Age varies by deposit but common in Precambrian to Paleozoic formations.

Uses & applications

Used extensively for figurines, sculptures, building facades, countertops, and decorative home items due to its softness for carving and ability to take a high polish.

Geological facts

The word 'marble' derives from the Greek 'marmaros', meaning 'shining stone'. Pure marble is white; the pink hue in this specimen is caused by trace impurities of iron oxide or manganese during metamorphism.

Field identification & locations

Identify by its 'sugary' texture and softness; it can be scratched with a copper penny or steel knife. It will also effervesce (fizz) when in contact with dilute hydrochloric acid. Commonly found in Italy, Greece, and the USA (Vermont/Georgia).
