Description: | Emerald is the green variety of the mineral beryl. The green colour of the emerald is derived from the element chromium, which is also responsible for the red colour of rubies. Probably the most famous emerald mines are those in Colombia, South America. The Romans mined emeralds in Egypt, and used a lot of these stones in their jewellery, but they sometimes substituted glass imitations for the real thing. | Source: | Tyne & Wear Archives & Museums | Identifier: | emu.ecatalogue.earthsciences.109751 | Go to resource |
