of the beryl
family. Fine emeralds are among the most valuable gemstones. Emeralds are created when chromium
combines with various impurities. Unlike most gemstones, inclusions, (called “jardin,” the French word for garden), are quite common in emeralds, so they lower the value much less than with other precious
stones such a diamonds
. As a remedy to lessen the appearance of common flaws, emeralds may be oiled or dyed. The most highly prized emeralds are mined in Columbia. A valuable emerald will be a bright, vividly colored
green. Those with a slight blue cast to the bright green are actually the most valuable color. Many emeralds seen in jewelry are of relatively low quality. If an emerald appears to be very fine, it may actually be a synthetic

This glass composition adheres to the metal through fusion under very high temperatures. The color of the enamel and its degree of transparency depend on the metal oxides that exist in the glass and the temperature at which the glass melts and coheres to the surface. Popular during the mid-Victorian period was a solid black, blue, or white enamel used to fill engraved designs.
