What is Labradorite?
Labradorite is part of the feldspar 
mineral group. The feldspar
group 
has two different varieties,
the orthoclase 
(alkali) ​feldspars,
which include amazonite,

orthoclase and moonstone, and
the 
plagioclase feldspars. The
plagioclase 
feldspars include
labradorite and aventurine

feldspar.


Labradorite is a colourful and interesting stone which has a range of colours and
optical effects. It is popular with 
jewellery designers and buyers. It is named after
 the source of the 
material - Labrador in Canada. It is also found in Mexico,Norway,
Russia, and Madagascar.

Labradorite has a metallic rainbow effect similar to black opal, except
with larger spots of colour. 
The effect is termed labradorescence. Similar to 
moonstone the effect is produced by the interference of light at the junctions
of internal structures. The material can be red, yellow, 
transparent orange
and colourless, and may be cut into a  
faceted stone. 

Labradorite can also have a semi opaque black - grey to brown - grey 

body with iridescent flashes of greens, blues, yellows, and oranges that
appear when it is moved in the light. This 
type of material is most sought
after by buyers.

opaque colour to the body , with a schiller in pink, orange,
blue or yellow. The most prized material has an electric- blue
schiller. Spectrolite can also display a cat's - eye effect.
