Common opal, sometimes known as “potch”, is a variety of opal that does not exhibit the flash and play-of-color seen in precious opal. However, common opal occurs in a variety of beautiful colors including pink.
It occurs in small deposits and are normally worked by small teams or families in a few field seasons or less.
Pink opal and yellow opal are both found in the same deposits, and their formation happened over many centuries in a locality known as Mooka Station (which is why this stone is also called Mookaite) in Western Australia, in an area where a great inland sea once existed.
