Spectrolite was the trade name given to an uncommon variety of Labradorite Feldspar that was discovered and mined in Finland in the 1940s. Quarrying of Spectrolite in Finland began shortly after the Second World War and has grown into a successful local industry. Today any Labradorite having a rich display of the full spectrum of colors is often called Spectrolite – regardless of the stone’s locality. Labradorite having the same play of colors as the Finnish material can also be found in Madagascar.
Labradorite is typically pale-to-dark blue, grey and green with flashes of orange or blue with high labradorescence, the optical phenomenon named after the stone.
Labradorite is formed when layers of two Feldspars that have different chemical compositions are arranged in an alternating structure. The colors seen in labradorescence depend on how thick these layers are combined with their refractive indices.
Spectrolite from Finland differs from other Labradorites because the base Feldspar is black, while other Labradorites typically have a transparent base color. This causes the color of Spectrolite stones to have a richer and more saturated appearance, especially when cut and polished into gems.
On the Market
Labradorite is found in Canada, in Labrador and Newfoundland, and also in Finland, where it is called Spectrolite. Other sources include Ukraine, Madagascar, and Australia.
Practitioners use Spectrolite to attract and hold courage, begin a transformation, unlock a breakthrough and start the flow of creativity. The energy of Spectrolite is thought to emit a constant energetic reminder that allows the wearer to recognize and fulfill their full potential. Spectrolite is used to symbolize leadership and will help to open the rainbow of possibilities hidden within the user’s personality. Spectrolite is also used to unlock and discover hidden skills to help create a brilliant future.
Treatments and Enhancements
Spectrolite and other Labradorite gemstones are natural and never treated or enhanced. When Labradorite is subjected to diffusion treatment with Copper in the lab, it produces a new, reddish color gemstone called Andesine.
Spectrolite Gems and Jewelry
Never use chemicals, harsh detergents, bleach or cosmetics near the stone. Avoid using ultrasonic or steam cleaners when cleaning Labradorite or Spectrolite. Mild soap and warm water and a soft brush should be used to wash gemstones and jewelry. Rinse Labradorite jewelry in clear water and dry it thoroughly. Store clean dry stones and finished jewelry in cloth to protect them, as all Labradorite is sensitive to pressure and can easily chip or crack.
