A strikingly scarce variety of Serpentine stone, Leopard Rock is an exquisitely coloured stone with pock marks similar to a leopard, hence the name, of yellow and black. These are inclusions of the ferromagnesian mineral, olivine. Leopard Rock is an olivine rich serpentine (known geologically as dunite) which forms part of a serpentine complex 2.6 billion years old.

It is a very difficult stone to carve and only very skilled sculptors will attempt this stone. Leopard Rock, when polished, has a beautiful glazed finish. Leopard Rock has a hardness between 6.0 and 7.0 on the Mohs Hardness Scale.
