A Feldspar mineral, also known as Spectrolite, or more descriptively, rainbow Spectrolite. Labradorite is named for Labrador, where it was first discovered (imagine that). Labradorite displays an iridescent effect known as labradorescence (once again, imagine that . . . ). When held at various angles under illumination, refracted colors range from blues and violets to greens, golds, yellows, and more – a polished surface serves to accentuate the effect – yet at a glance, Labradorite can appear to be a nondescript gray rock. This particular specimen is large and has some amazing flash. It is polished all around and flashes from every surface, but the front face is really spectacular – no matter the angle, it flashes, particularly deep blue with some gold, and brilliantly. Another one of those specimens where the debate from guests will be whether it’s real or not – but it certainly is!
