Labradorite is a massive microcrystalline mineral composed of Sodium Calcium Aluminium Silicate and is found in Labrador, Canada. Material very similar in composition is also found in Finland and Madagascar where it is called Spectrolite. This Feldspar occurs as an opaque dark gray that exhibits a broad sheet or play of colour, typically Blues and/or Greens though rarely with Red or Orange hues as well. These plays of colour are known as Labradorescence, and are identical to the Adularescence found in clear based Moonstones.

All Feldspars exhibit perfect cleavage and easily split into rhombs. This natural cleavage and the fact that the stone exhibits differential hardness depending on directionality, make cutting Feldspars into perfectly symmetrical shapes quite difficult.

Labradorite is relatively common and therefore is modestly priced although supplies in recent years have been slowly depleted. Pricing on average specimens is modest but extremely vibrant pieces do bring a premium. Clear Rainbow Moonstone or very fine Labradorite is comparable with Precious Opal and is priced out of its’ normal class especially when cut as fine small beads. Labradorite has one distinct advantage over Opal in that it is not sensitive to dehydration and can weather freezing temperatures without harm.

We have a fantastic variety of raw, finished and set pieces in stock at most times. Feel free to come in and view this interesting gem.
