Labradorite, a feldspar mineral, can display an iridescent optical effect (or Schiller) known as labradorescence. It is an intermediate to calcic member of the plagioclase series. The streak is white, like most silicates. As with all plagioclase members, the crystal system is triclinic. It occurs as clear, white to grey, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites.
Spectrolite is an uncommon variety of labradorite feldspar, which exhibits a richer range of colours than labradorite. Spectrolite was initially a brand name for material mined in Finland, but is sometimes used to describe labradorite whenever a richer display of colours is present, regardless of locality.SIMILAR TO SEEN: The image shows an example of the single specimen you will receive.
