Sunstones, as their name suggests, echo the warm colouring of the sun, with crystals ranging from a golden yellow to a fiery burnt orange colour.
Sunstones are also known as ‘Aventurine Feldspar’ and are a form of Plagioclase Feldspar. They have a distinct spangled appearance from copper inclusions. Light reflects off these inclusions creating an unusual and attractive schiller. The colour and schiller in a Sunstone is typically strongest at the centre of the crystal, paling around the edges to create a flame-like optical effect.
