Physical properties

Hardness 3-4 on Mohs scale, predominantly white and brown mottled coloration, vitreous to dull luster, composed primarily of calcium carbonate in aragonite or calcite crystal structure.

Formation & geological history

Formed through the biological precipitation of calcium carbonate by marine mollusks, subsequently preserved in sedimentary rock strata over geological timescales.

Uses & applications

Valued by fossil collectors, used in decorative displays, educational exhibits, and occasionally in coastal jewelry.

Geological facts

Murex shells have a rich history dating back to antiquity, famously used by the Phoenicians to produce royal purple dye. Fossilized specimens provide key paleoclimatic data.

Field identification & locations

Easily identified by its distinctive spiky whorls and spiral structure. Commonly found in marine sedimentary formations worldwide.
