Moonstone is a feldspar gemstone known for its soft, glowing optical effect called adularescence, which looks like moonlight floating beneath the surface.This shimmer comes from alternating layers of orthoclase and albite that scatter light and create its signature ethereal glow. 

Cat’s eye stones are defined by chatoyancy — a sharp, moving band of light that resembles a feline’s eye.A rare moonstone variety that displays both adularescence and a cat’s eye band. Its hues range from pale blue to shimmering gray, and the moving line of light is caused by fibrous inclusions inside the stone.

Tiger’s eye is a quartz gemstone known for its silky, reflective bands and warm tones of gold, brown, and bronze. Its chatoyancy comes from fibrous crocidolite inclusions that have been replaced by quartz over time, creating a shimmering, layered effect similar to a cat’s eye but broader and more wavelike.
