LABRADORITE PURPLE
Mined at Fort Dauphin Madagascar -Africa 
A  purple tone  in this sspecimen is very unique. This specimen does have a play of purple with other colours. 
well polished.

Labradorite  a feldspar mineral, is an intermediate to calcic member of the plagioclase series.. The streak is white, like most silicates. The refractive index ranges from 1.555 to 1.575. Twinning is common. As with all plagioclase members the crystal system is triclinic and three directions of cleavage are present two of which form nearly right angle prisms. It occurs as clear, white to gray, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites.

The iridescence is the result of light refracting within lamellar intergrowths resulting from phase exsolution on cooling in the Boggild miscibility gap.

Gemstone varieties of labradorite exhibiting a high degree of iridescence are called spectrolite; moonstone and sunstone are also commonly used terms, and high-quality samples with good iridescent qualities are desired for jewelry.
