Larvikite

Larvikite is a feldspar-rich igneous rock, called a monzonite and is named for the town in Norway where it was found. One characteristic of this stone is its unique iridescence, caused by the presence of interlocking feldspar crystals within the structure of the stone. Through the wonders of nature, each polished gem has a sheen that sparkles with deep silver tones. Usually, this stone is used in ornamental and decorative purposes.
