rhinestone
UK: ˈraɪnstəʊn | US: ˈraɪnstoʊn
n. An imitation gemstone made of glass or crystal, often cut to sparkle like a diamond.
The term "rhinestone" originates from the 18th century, when rock crystals collected from the Rhine River (German: Rhein) were popularly used as inexpensive diamond substitutes. Over time, the name became associated with any glittering artificial gemstone, even as production shifted to glass or synthetic materials. The morpheme rhine preserves the geographic connection, while stone reflects the material's gem-like appearance.
