Labradorite 6-7mm (approx) Small Nugget Beads

Labradorite is a type of feldspar.  It was first found in 1770 on the Labrador Peninsula in Canada, from which it received its name.  It is usually grey but in different angles of light displays a variety of colour - mainly blue.  This is called "schiller" effect.  It is not the result of surface colour but light reflected internally across cleavage sections creasing what is known as labradorescence.
