Chrysoprase of high quality has been produced commercially since the early 1960s from the Marlborough district of central Queensland, some 90 km to the northwest of Rockhampton. Small quantities of chrysoprase also have been produced intermittently from deposits at Mount Davies in the remote northwest of South Australia, and adjacent deposits at Wingelina in Western Australia. More recently, chrysoprase has been won from Yerilla in Western Australia.
Chrysoprase is usually translucent, but may become opaque in poorer quality material. A small proportion of stone is semi-transparent to transparent and, if of good colour, is highly prized and valued. Chrysoprase is fashioned principally into cabochons, beads, bangles, or is carved to yield jewellery and other ornamental objects. It is easily worked and takes a fine polish. The highest quality material is a rich apple green of even colour, without flaws, fractures, inclusions, cavities or other imperfections.
