Green-and-white marble (likely serpentine-bearing marble)

Calcite- or dolomite-rich marble with green serpentine/chlorite minerals; exact identification requires testing

AI-generated identification · may be incorrect

Rough, pale gray-white stone with dark green flecks and veins; likely Mohs 3–4 if calcitic, up to about 5–6 if dolomitic or serpentine-rich. Typically has a crystalline texture and no consistent cleavage; luster is dull to slightly vitreous on broken surfaces.

AI Estimated Value

About $1–$10 as a small, common rough specimen; more if testing or polishing reveals distinctive, attractive material.

Physical properties

Formation & geological history

Formed when limestone or dolostone recrystallized during metamorphism, with green minerals introduced or produced by associated alteration. Such rocks form in many geological ages and mountain belts.

Uses & applications

Marble is used for building stone, decorative objects, and sculpture; attractive pieces may be polished for lapidary or collectible use.

Geological facts

The image shows a natural geological specimen, but visual inspection alone cannot confirm marble or distinguish its green minerals. A calcite-rich piece should fizz with dilute acid and scratch readily with a steel blade.

Field identification & locations

Look for interlocking crystals and a sugary texture; test hardness and acid reaction to separate marble from similar green-speckled rocks. Marble occurs worldwide in metamorphic belts, including Italy, Greece, India, and the United States.
