At Joyworks we are rhinestone lovers and love the sparkly stuff! We have a nice supply of pretty necklaces in many fun styles. Although glass "stones" have been around for hundreds of years,they became more common when Swarovski,a famous crystal maker, created a machine in 1881 that cut facets in leaded glass and revolutionized the jewelry making process. By the 1920s,costume jewelry manufactures and rhinestone pieces became widely available. I'm glad that they're easy to find beacuse I love to collect vintage rhinestone jewelry...it's hard to resist all that gitters!
