Mineralogical characteristics
Sunstone is a gem-quality variety of oligoclase, an abundant plagioclase feldspar. It owes its color and shine to inclusions of hematite or goethite arranged in parallel. In some cases, it may contain copper instead of hematite, as occurs in Oregon sunstone.
Sunstone mainly forms in granitic pegmatites, granites and felsic igneous rocks. It can also appear in metamorphic rocks such as schists and gneisses. It usually occurs in massive or granular habit and, less frequently, in tabular crystals.
Deposits
United States, Norway, Russia, Canada, India and Australia.
