Labradorite is a gemstone that was named after Labrador in Canada, where it was found on the Isle of Paul, near Nain in 1770.
Labradorite is an unusual mineral. It can display a beautiful iridescent play of colors, caused by internal fractures in the mineral that reflect light back and forth, dispersing it into different colors. This effect, known as labradorescence, gives Labradorite its appeal and fame.
It shows labradorescence - a shiller effect in lustrous metallic tints, often blue and green, and sometimes the complete spectrum. This effect is caused by interference of light from lattice distortions resulting from alternating microscopic exsolution lamellae of high- and low-calcium plagioclase phases.
Labradorite belongs to the Plagioclase Feldspar group, an isomorphous solid solution series. Albite is one member, containing sodium and no calcium.
Chemical Formula: (Ca,Na)Al1-2Si3-2O8; Hardness: 6 - 6.5; Member of: Feldspar Group;
