For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.The History of JewelryRhinestones have a glittering past. Originally rhinestones were referred to Czechoslovakian or Bohemian glass dating as far back as the 13th century in Bohemia and the Czech Republic. Both places have a history steeped in beautiful hand blown glass as well as molded and cut glass.By 1918 glass was no longer limited to functional items. Czechoslovakian glass began to make its appearance in dazzling and brilliant jewelry. This Czech glass became known as rhinestones.Rhinestones were manmade gems from highly refined glass. By using various metals the glass was colored to the desired shade. It was then pressed into molds. Each stone was then ground and polished by machine, resulting in a brilliant glass stone. Often the stones were foiled on the back which increased their brilliance.Today, the same refining process is still used. You will often hear rhinestones referred to as paste. Originally paste was referred to a glass stone that was made of ground glass which was molded and then melted, producing an opaque dense glass frosted stone. Paste had many air bubbles and swirl marks. The high lead content glass was then polished and faceted, and set on either copper or silver resulting in a brilliant stone. Today the term “paste”usually refers to rhinestones. In Europe rhinestones are often referred to as paste, strass, and diamante.Austria is another area with a history in rhinestone production. In 1891 Daniel Swarovski created a new glass cutting machine which quite literally revolutionized the jewelry business. This machine could cut faceted glass, producing finely finished product in a very short time. Prior to this invention it would take a very long time for each stone to be cut by hand and finished. Swarovski’s background in glass making, combined with his glass cutting machine soon found him producing rhinestones with a lead content of over 30%. The brilliance of these rhinestones was superior to anything seen on the market. Swarovski wasn’t content with his invention and the best rhinestones ever seen. His next invention was once again transforming to the jewelry industry. He created a vacuum plating for the backs of the stones with silver and gold, reducing the need forhand labor. Still today Swarovski rhinestones are recognized as the highest quality in the industry. Over 80% of rhinestone jewelry manufactured in America use Swarovski rhinestones.Rhinestones have played an important role in costume jewelry for hundreds of years. It is used to enhance and decorate the costumes, and sometimes rhinestones will provide the entire design. During the Victorian period common design patterns for jewelry included snakes, flowers, and hands most often adorned with rhinestones.The 1890s were a time for extravagant jewelry heavily with rhinestones. As time moved forward designs became simpler with figural shapes once again making their fashion statement. However this time they were small and more elegant with small rhinestone decorations.During the Edwardian period extravagance had made a comeback with diamonds and pearls being the focal point. Once again rhinestones were in heavy use, often used to imitate the real thing.During the 1920s fashions were rapidly changing. Dresses had gone from tight, fitted to a looser, more comfortable style. Two distinct styles occurred during this ear --- the feminine style and the androgynous style (having both female and male characteristics). Jewelry from the 1920s drew on the art decoration period. The majority of rhinestone jewelry was made with clear rhinestones.As the 1920s moved jewelry once again became bolder. Dramatic color was in style. Designer Coco Chanel was an integral figure in setting the stage for jewelry of this era.During the 1930s, during the Depression, labor-intensive fashion was no longer feasible. While the world in chaos, jewelry represented an affordable comfort to many women. Inexpensive costume jewelry could be used to revitalize an old outfit. The industry began to produce bright colored enamel pieces decorated with rhinestones. Dogs, birds, or cats with a rhinestone eye were commonplace.The jewelry during 1940s once again became big and bold with rhinestones being produced in every imaginable color, large stones set on large bold setting was the norm.By the 1950s there were two very distinct looks --- elegant and sophisticated for the more mature woman, and casual and fun for the younger woman. The 1950s saw jewelry that were made completely from rhinestones. For the younger woman were flirty prices, for the older woman sophisticated elegance. Whole sets of rhinestones jewelry became extremely popular.In 1953 the aurora borealis rhinestone was introduced to the market with its fabulous array of color. It was an instant hit.By 1906s women were wearing very functional clothing. By the late 1960s the hippie fashions were extremely popular with their roots tied to Mother Nature. Tie dyed shirts, long flowing skirts, frayed jeans were everywhere. This generation had no interest in rhinestone jewelry.By the mid 1970s, the punk look had been born and the rhinestone was revitalized. It was the disco movement brought the rhinestone back to center stage. The disco movement turned into the club movement during the 1980s and rhinestone jewelry continued to gain popularity.Since the 1970s rhinestones have remained main stream in the jewelry world. They continue to gain popularity and today there is a style to suit almost every one’s needs. There is rhinestone jewelry which is perfect for a bride, rhinestone jewelry for a prom girl, rhinestone jewelry for the young and fun crowd, the business woman, the sophisticated woman, and the mature woman. Beautiful pieces of rhinestone jewelry adorn almost every woman’s accessories.If trends are an indication of the rhinestones future, it appears to have a brilliant healthy life ahead of it. Pleasing for most women with a fashion sense who instantly recognize the value and beauty of rhinestones!1.
