Thermoset is a form of lucite which has been molded into interesting shapes. It was widely used by Coro, Lisner and other vintage jewelry designers during the 1950s and 1960s. Often the settings are open backed and the shapes are curved. Thermoset pieces normally are cabochons, with the bottom area being flat for ease of inserting into settings. It was most commonly used in necklaces, earrings and bracelets, but can be found in other types of jewelry too.
This classic seven-link and chain necklace is composed of individual, light & medium blue, six-pointed star, thermoset cabochons mounded in a silver-tone setting. The slightly curved cabochons are glossy and velvet smooth to the touch. The seven links measure 7 1/2" in length and 3/4" with the addition of 5" on chain on either end, giving total length of 17 1/2 inches. There is a hook clasp to easily adjust to the desired length. Great color and near mint condition. The piece is not marked as to maker.
