Other forms: rhinestones
A rhinestone is a sparkling imitation jewel that looks like a diamond but is usually made of glass or plastic.
If a long evening gown is covered with sparkling stones, the odds are good that they are rhinestones rather than precious gems. The word comes from the French caillou du Rhin, "Rhine pebble," named for the original rhinestones: small rock crystals found along the Rhine River. Today, rhinestones are made from cut glass or acrylic and are closely associated with country music stars like Dolly Parton, late-career Elvis Presley, and the flashy pianist Liberace.
