Spectrolite is an uncommon variety of labradorite feldspar.
A richer range of colors than labradorite (that shows only tones of blue-grey-green) and high labradorescence. It was initially a brand name for material mined in Finland, but is sometimes incorrectly used to describe labradorite whenever a richer display of colors is present, regardless of locality: for example, labradorite with the same play of colors has also reported from Madagascar. The difference between Finnish spectrolite and other labradorites is that crystals of the former have considerably stronger colourfulness than other labradorites, caused by the black base color of feldspar; other labradorites have mostly a transparent base color. This stone is often cut as a lapidary cabochon, similar to plain labradorite, to enhance the effect and is used as a gemstone.

Finnish geologist Aarne Laitakari (1890–1975) had described the peculiar stone and sought its origin for years when his son Pekka discovered a deposit at Ylämaa in south-eastern Finland while building the Salpa Line fortifications there in 1940. The Finnish stone exhibits a uniquely vivid iridescence and a full spectrum of colors, hence the name of this gemstone was coined by the elder Laitakari.
After the Second World War has become a significant local industry. In 1973 the first workshop in Ylämaa began cutting and polishing for jewels.

Spectrolite has a hardness of 6 to 6.5 on the Mohs scale and a specific gravity of 2.69 – 2.72.

Spectrolite is the very high grade of dark based Labradorite that is found only in Finland. The name “Spectrolite” is a trade name given to this material by the Finns, and only this material can truly be called Spectrolite.

The astrological signs of Spectrolite are Scorpio, Sagittarius and Leo. Associated with the Winter season, and the January Moon (Wolf Moon).
