Labradorite: Formula- (Ca,Na)[Al(Al,Si)Si2O8]. A variety of Anorthite
Labradorite can display an iridescent optical effect (or schiller) known as labradorescence.
The cause of this optical phenomenon is lamellar structure caused by an exsolution process due to a miscibility gap. The effect is visible when the lamellar separation is between 128 to 252 nm. The lamellae are not necessarily parallel, and the lamellar structure is found to lack long range order (Bolton et al.,1966).
Color: Pale green, blue, colourless, grey-white
In our experiences with labradorite it has assisted with aligning the physical and etheric bodies . Some have taped labradorite to warts to remove them. Great for reliving stress and balancing hormones. As this is a stone of transformation it can assist with the ascension process.
