Originally, rhinestones were rock crystals gathered from the river Rhine. The availability was greatly increased when around 1775 the Alsatian jeweller Georg Friedrich Strass had the idea to imitate diamonds by coating the lower side of glass with metal powder. Hence, rhinestones are called Strass in many European languages. At Mustjewels.com we provide excellent Costume Jewellery designs for Rhinestone Necklace Sets and Earrings.
