Olivine is my favourite mineral. When its quality is high enough for it to be cut as a gem, it's known as Peridot.
Look for Olivine "bombs" in amongst scoria gravel. They range in size from a walnut to a lemon. The mineral itself often crumbles.
It is found beyond Earth, even in meteorites. Its earliest known classical source was at St. John's Island ( now Zabargad island ) in the Red Sea.
Victoria's largest deposit is at Mortlake, in the western district. These samples come from there.
Installed here is my die-cast lamb, appropriate representitive of the world-famous wool that has been grown in this region of extinct volcanoes.
None of us would exist without the valuable generosity of the earth given to us.
Emblematic of purity and morality, and of spring, Olivine/Peridot is supposed to ward off negativity.
