Petalite

Petalite is also known as Castorite. It is a lithium aluminum phyllosilicate mineral. Petalite occurs as colorless, pink, grey, yellow, yellow grey, or white. It occurs in lithium-bearing pegmatites with spodumene, lepidolite, and tourmaline. Petalite is an important ore of lithium, which is used to make batteries and the production of glass. It is converted to spodumene and quartz by heating to ~500 °C and being put under 3 kbar of pressure. Petalite has a low thermal expansion rate, making it a popular player in the glass and ceramics industry. Some brides also use petalite as a ring instead of a diamond, since the stone sparkles similarly to a diamond.
