Physical properties

Hardness of 6.5 to 7 on the Mohs scale, multicolored with greens, browns, reds, and purples, waxy to vitreous luster, and conchoidal fracture.

Forms from silica-rich fluids precipitating in sedimentary or volcanic environments over millions of years.

Used primarily in lapidary arts, tumbled stones, ornamental carvings, and gemstone jewelry.

Fancy jasper is known for its earthy multicolored banded patterns, often called the stone of tranquility.

Identified by its high hardness, opaque nature, and distinct multicolored patterns; commonly sourced from India, Madagascar, and South Africa.
