About Labradorite


Introduction

 

Labradorite was originally discovered in on St. Paul Island, Labrador, Canada in 1770. Pieces of the stone were found amongst the artifacts of the Red Painted People of Maine. Spectrolite was discovered in Finland during World War II. It is considered to be the gem quality of Labradorite.


The name labradorite comes from the province of Labrador in Canada, which is a famous locality for labradorite with an iridescent play of colors. Feldspar is derived from the German word feld which means field. Iridescent labradorite is sometimes referred to as spectrolite.

 

A mineral is a naturally occurring inorganic solid substance that is characterized with a definite chemical composition and very often with a definite atomic structure.Nature never ceases to surprise and this is especially true of labrodrite, which uniquely captures the intense colours of the ocean, from the dark greens of the deep to the bright blues of the surface. When polished, the overall visual effect of the black inserts contrasting with the blue and green has the appealing look of the sea as the light effects its marine colours. From Madagascar, a precious stone suitable to grace any kind of building. Labradorite Blue Austrate is suitable for both inside and outside use.

 

The Labradorite is internationally a widely-known ornamental material, not only used as gemology but also for the preparation of monuments and in the finishing or construction work of palace and luxurious constructions. Its name recalls the region of Labrador in Canada, where it was discovered in the 18th century. The first labradorite was returned in Europe in 1775. Labradorite discovered in Canada on 18th century.

Chemical composition:- Na, K and Ca

 

General formula – WZ408 in which W = Na, K, Ca and Ba; Z= Si and Al

(1) Na Al Si3 O8

(2) K Al Si3 O8
