SPECTROLITE

MADAGASCAR

BEAUTIFUL GOLD ORANGE BLUE GREEN COLOUR

Spectrolite is a hard and rare variety of labradorite feldspar. Spectrolite has a specific gravity of 2.69 to 2.70. The variety is noted for iridescence of spectrum colours from blue to red. Finnish geologist Aarne Laitakari (1890—1975) had described the peculiar stone and sought its origin for years when his son Pekka discovered the deposit at Ylämaa in south-eastern Finland while building fortifications there in 1940. Although labradorite is found in Labrador, Norway, Madagascar and Russia in addition to Finland, the Finnish stone exhibits a uniquely vivid iridescence. The name spectrolite was given to it by the elder Laitakari; it is a commercial name and is properly used only of gemstone-quality material from the Ylämaa deposit.
