This material, known as Lemon or Citron Chrysoprase for its lemon-yellow color, comes the Eastern Goldfields area of from Western Australia.
Though named "Chrysoprase", it is actually magnesite. The color is very pale yellow, (slightly greenish).
It is found in a belt of rocks that stretch from Norseman in the south to near Wiluna in the north. It occurs in many of the same locations as that of the well known green chalcedony named Chrysoprase, most notably Yerilla, Marshall Pool & Goongarrie but in numerous other places as well.
Known for manifesting optimism, joy, and happiness, the Chrysoprase crystal stone is one of the best for encouraging a more positive outlook on life.
