Originally, rhinestones were rock crystals gathered from the riverRhine, hence the name, although some were also found in areas like the Alps, but today the name "rhinestone" applies only to varieties of lead glass known as crystal glass. The availability was greatly increased in the 18th century when the AlsatianjewellerGeorg Friedrich Strass had the idea to imitate diamonds by coating the lower side of lead glass with metal powder. Hence, rhinestones are called strass in many European languages. As opposed to the classic rhinestones, which had a metal powder coating on the bottom side only, several companies have opted to mass-produce iridescent lead glass, by reducing the metal coating thickness and applying it uniformly, not using metal powder with a binder but by applying various forms of metal deposition : Favrile glass by Tiffany in 1894, Carnival glass under the name "Iridrill" by Fenton in 1908, "Aurora Borealis" glass by Swarovski in 1956 and PVD-coateddichroic glass in the late 20th century, amongst many other decorative lead glasses coated with a thin metal layer sold under various commercial names such as "rainbow glass", "aurora glass" and such. Rhinestones can be used as imitations of diamonds, and some manufacturers even manage to partially reproduce the glistening effect real diamonds have in the sun.
Compositions
Typically, crystal rhinestones have been used on costumes, apparel and jewelry. Crystal rhinestones are produced mainly in Austria by Swarovski and in the Czech Republic by Preciosa and a few other glassworks in northern Bohemia. In the US, these are sometimes called "Austrian crystal". The rhinestone-studded Nudie suit was invented by Nudie Cohn in the 1940s, an Americanization of the matador's "suit of lights". Rhinestone material is often used as an alternative to sequin.
Rhinestones are sized by using the term "ss", or stone size, followed by a number to indicate size. SS is more commonly used for apparel means, while PP is used for jewelry.
Hot-fix rhinestones
Hot-fix rhinestones, also called heat-transfer rhinestones, are mainly used for apparel. The flat bottom of the stone has a glue backing and, when heated, melts onto the surface of the clothing. These can be adhered using a regular iron, although it is recommended to use a heat press, as they are able to reach higher temperatures while applying heavy pressures resulting in a more professional quality.
