Semi-precious stones make for elegant earrings
Pearls are prized for their luster and iridescence. One of the most distinctive features of a nacreous pearl is the way it seems to glow from within. The reflection of light rays gives pearls their luster and unusual beauty. The multiple layers of nacre give it iridescence as they act like tiny prisms, refracting light so that it appears as all the colors of the rainbow.
