Physical properties
Mohs hardness of 6.5 to 7; displays earthy tones of gray, brown, and black with abstract linear patterns; exhibits a vitreous to dull luster.
Formation & geological history
Formed through the metamorphism of limestone or clay-rich sediments where mineral-rich groundwater deposits silica in fractures over millions of years.
Uses & applications
Primarily used for lapidary arts, making polished beads for jewelry, and as a decorative collector mineral.
Geological facts
Its distinct abstract patterns resemble Picasso paintings, earning it the trade name Picasso Stone or Picasso Marble.
Field identification & locations
Identified by its dense, opaque microcrystalline structure and striking landscape-like patterns; commonly sourced from Utah, USA.
