Sunstone is a gem variety of oligoclase feldsper. Oligoclase is a variety of plagioclase feldspar, which is itself an isomorphous mixture of albite (sodium aluminium silicate) and anorthite (calcium aluminium silicate).
In common with other feldspar gems, it displays a schiller of coloured light, caused by inclusions or its crystal structure creating interference effects of light.
Sunstone is a rich golden or reddish brown colour, with plays of red yellow and orange light, sometimes also with green, caused by the inclusion of microscopically thin plates of goethite or hematite.
The Gemstone Sheriff program allows our members to request an audit on any auction, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
