Roberto Cavalli creates with the eye of an artist and the touch if an expert craftsman. His designs are completely original. An audacious master of patterns, he specializes in startling juxtapositions if materials, textures and themes: patinas and metallurgy, zebra skins and Op Art, leopard spots and giant flowers, embellished leathers and embroidered jeans, all reproduced in a vibrant technicolor rainbow. An entire coterie of artists and celebrities, from Madonna to Lenny Kravitz, has adopted his doctrine of glamour, making Cavalli's name synonymous with pop baroque, young decadence and sensual allure. Cavalli's success-there are those who consider him a cult figure-reflects the spirit of our times and our fascination with all that is unique.

Pure silver has a beautiful white color and luster; it is almost as plastic as pure gold and like it very soft. Silver does not tarnish in natural air, but when it comes in contact with sulfur compounds it readily forms black silver sulfide. The sulfur compounds which act on silver are found in small quantities in the air as a result of burning coal and illuminating gas, while larger amounts occur in vulcanized rubber, wool, and foods like eggs.An alloy of 925 parts fine silver and 75 parts copper is called 925-1000 fine or what is commonly known as sterling silver.This alloy is used almost universally for jewelry and the best silverware.
THE CHEMICAL COLOR COATINGS DIAMOND SCAM: A little paint goes a long way. This very deceptive practice involves a little point of blue or purple paint on the lowest tip of the diamond, called the culet. This is small enough that you might not detect it, but the location spreads the color throughout the stone. This counters the yellow tint in lower color grades, making a diamond look like a more expensive, colorless grade.
Another interesting use of bracelets, only invented quite recently, is the charity bracelet. These are usually made from silicone, and bear a slogan such as 'make poverty history' or 'help the aged'. The idea is that if you see someone wearing one, you are likely to mention it, and then they will tell you a little about the cause and why it matters to them - a good way of getting people to talk about charities they care about.
