About Emerald: Emeralds are the birthstone for May and the 20th and 35th wedding anniversary stone. Emerald belongs to the beryl group of gemstones and is one of the four precious gemstones in the world, which includes sapphire, ruby, and diamond. The name comes from the French word 'esmeralde', meaning 'green stone'. The color comes from chromium and vanadium deposits. Even though emeralds have been found in many places round the world, Columbia, Brazil, and Zambia have the largest sources. Many are immersed in oil to enhance their color, often using a cedar oil. This is usually done at the mine where the stone is sourced. These emerald stones have been dyed for a more uniform color.
