Spectrolite Gemstones

Spectrolite Rough from Finland

Spectrolite is a gemstone renowned for its iridescent play of colors and mystical allure. Originating from Finland, spectrolite is a variety of labradorite that was first discovered in the town of Ylämaa in the 1940s. Its name is derived from the word "spectra" due to the spectral colors that dance across its surface when exposed to light.

Labradorite is known for its remarkable iridescence. This schiller or metallic luster can be seen when light hits the stone from particular angles. Most typically, these metallic tints are violet, blue and green. This effect is so unique to labradorite that it is referred to as labradorescence. The labradorescent effect is believed to be due to the presence of very fine platelets of varying composition as well as minute inclusions of limenite, rutile and possible magnetite, which cause the diffraction of light.

Some rare specimens of labradorite display a full spectrum of colors, not only violet, blue and green; but also yellow, orange and red. These rare specimens have been given the name spectrolite. The name was introduced by the Finnish geologist Aarne Laitakari (1890-1975), former director of the Geological Survey of Finland. Laitakari's son, Pekka, discovered the first spectrolite deposit at Ylämaa in South-Eastern Finland near the Russian border while building the Salpa Line fortifications there in 1940.

The mining location of spectrolite is primarily concentrated in the quarries of Ylämaa, where skilled miners extract the gemstone from the earth's depths.

Polished Spectrolite

Spectrolite and labradorite belong to the plagioclase feldspar group, a series of mixtures of sodium and calcium aluminum silicates. Other members of the plagioclase group include sunstone and andesine. Labradorite has a hardness of 6 to 6.5 on the Mohs scale and a specific gravity of 2.69 to 2.72.

Spectrolite is believed to possess powerful metaphysical properties that promote strength, intuition, and creativity. It is said to enhance one's spiritual connection and provide protection against negative energies. Some also believe that spectrolite can stimulate the imagination and inspire artistic expression.

Spectrolite is considered a rare and valuable gemstone due to its limited availability and stunning beauty. The price of spectrolite can vary depending on factors such as size, color intensity, and overall quality. Spectrolite gemstones can be used to create exquisite pieces that showcase its mesmerizing colors and unique charm. Rings, necklaces, earrings, and bracelets adorned with spectrolite can add a touch of elegance and mystique to any ensemble
