Semi precious gemstone Labradorite cabochons have a background color of dark gray, but they display a beautiful iridescence, giving off rainbow-colored reflections known as labradorescence when light hits it in certain directions. The usually intense colors range from the typical blues and violets through greens, yellows and oranges. Some rare designer cabochons display all these colors simultaneously.
Labradorite is a plagioclase feldspar. Labradorite shows the iridescent display of colors due to minute inclusions of another mineral.
It is named after where it was first found in 1770; Labrador, Canada, although our gemstone cabochon material comes from the Tulear Province of Madagascar. It is also found in other areas around the world.
Labradorite with superb labradorescence is produced from a few deposits in Finland. The best of this material was given the name Spectrolite by the director of the Geological Survey of Finland.
Careful consideration must be given to orientation when cutting Labradorite cabochons-to make sure the stone has the best flash or labradorescence.
Labradorite cabochons have a hardness of 6-6 1/2.
Metaphysical Properties of Labradorite: Labradorite is thought by some to symbolize the moon and the sun, and in fact has been found to be an ingredient of moon rock. It is said to assist the wearer to handle changes, promoting strength and perseverance.
