Named for the type locality at Laurium, also called Laurion, in Greece. Laurionite is a rare mineral that is “produced by the action of saline water on lead-bearing slag [and] in the oxidized zone of lead-bearing mineral deposits.” It can be found in, additionally, Italy, Germany, South Africa, England, Wales, Turkmenistan, Australia, and the United states, among a few others. Laurionite is slightly soluble in water, more so in hot water.

The name of Lavendulan was recently discovered to be a misnomer after the lavender color of the “type” specimen, which was later discovered to be a mixture and of no relation to the modern Lavendulan which has not been found to exhibit a lavender color. Lavendulan is an uncommon mineral in oxidized copper deposits and can be found in Germany, England, the Czech Republic, Scotland, France, Spain, Tunisia, Iran, Namibia, Morocco, Chile, Australia, and the United States.
