Spectrolite is a high grade variety of Labradorite. The difference between the two is Labradorite is usually a gray color, where Spectrolite is dark gray or black, giving a better background to make the colors pop more. Also Spectrolite cabochons display the whole spectrum of colors-hence the name.
Spectrolite comes from only one location, Finland.
