Physical properties
Hardness: 3-4 (Mohs scale); Color: Tan, brown, grey; Luster: Dull/Earthy; Texture: Highly weathered, craggy, and pitted surface resembling elephant hide.
Formation & geological history
Formed from sedimentary limestone/dolomite layers over millions of years, which have undergone intense chemical and physical weathering, particularly through water erosion (karstification).
Uses & applications
Primarily used in aquascaping for freshwater aquariums, terrariums, and as ornamental garden stones or suiseki (viewing stones).
Geological facts
Also known as 'Ancient Stone' or 'See-gebirge stone', it is prized for its high contrast and deep textures which provide a natural, aged look in miniature landscapes.
Field identification & locations
Identify by its unique 'skin' texture and deep ridges. It may slightly increase water hardness and pH in aquariums due to its calcium carbonate content.
