"  Valued at: $125 to $850 each These bangle Bakelite bracelets were designed during the Art Deco period from the 1920s through the 1940s, and were made in a variety of vibrant colors and carved motifs. They originally sold for $10 to $40 apiece. These values now: green ($450), blue ($850), red ($600), yellow ($125), and butterscotch ($375).   What is it?  In 1907, chemist Dr. Leo H. Baekeland invented Bakelite in Yonkers, N.Y. Bakelite is a material made of formaldehyde and phenol and was considered one of the first plastics of its kind. Bakelite was produced in a variety of colors, the heated and molded into pieces of costume jewelry including bangle bracelets, pins, brooches, and even baby rattles. The jewelry was then carved, laminated or inlaid with decorative designs. Bakelite bangles were often worn in groups of three, five, or seven. Thinner bracelets were commonly sold in sets.   What to look for?  According to Ava Polan, owner of the online resource bakeliteboutique.com, vintage Bakelite jewelry, especially bangles and pins, has soared in popularity. Since this plastic naturally oxidizes when exposed to the air, the colors have changed over time. For example, a bracelet that was once turquoise will have darkened to butterscotch brown. Undecorated examples are not as desirable as intricate ones. Vintage bangles range from $100 to $12,000, depending on color, design, and size. "^^<http://www.w3.org/2001/XMLSchema#string>
