Rhinestone
A rhinestone, paste or diamanté (UK: DEE-ə-MON-tay, US: DEE-ə-mon-TAY) is a diamond simulant originally made from rock crystal but since the 19th century from crystal glass or polymers such as acrylic. == Origins == Originally, rhinestones were rock crystals gathered from the river Rhine, hence the name, although some were also found in areas like the Alps (the source of the Rhine).
