The namecomes from the old French word ‘esmeralde’, which was derived from the Greek word ‘smaragdos’ meaning ‘green stone’. By definition, Emerald is any medium to dark green beryl coloured by chromium. Green beryl coloured only by vanadium is not considered to be true emerald, but rather as simply green beryl. Since the 1960s, the American jewellery industry changed the definition to include vanadium coloured beryl as ‘Emerald’, but in the UK and Europe, they are still not recognized as such. The historical green colour of Emerald is unparalleled in the world of gemstones and it is considered as one of the most ‘precious four’ of all gemstones, which also includes Sapphire, Ruby and Diamond. Although Emeralds are one of the most valuable gemstones available today, most are very heavily included, rendering their resistance to breakage as generally poor.
Though Colombia is the most the most famous source for ‘deep green’ Emeralds, Emerald deposits are mined from many locations around the world. Recent decades have seen Emerald production increase as a result of newly discovered deposits in South America, Africa and across Europe. Today, Brazil and Zambia are now some of the leading producers of fine Emeralds, following Colombia. Brazilian Emeralds are prized for their excellent clarity and slightly yellowish green colour, while Zambian Emeralds are desired for their slightly bluish green colour, which is similar to that of Colombia’s ’emerald-green’ Emeralds.

Almost all natural Emeralds contain distinct characteristic inclusions and almost all are treated with oil or resin to fill tiny fissures and cracks. It is the presence of these flaws and oil which makes it quite easy to identify and distinguish natural Emeralds amongst other similar gemstones. Artificial light will expose and amplify inclusions and fractures that prove the stone to be a natural Emerald. Emerald colour is owed to trace amounts of chromium and vanadium, and colour is best admired under natural daylight. One of the easiest methods to identify green Emeralds is to test for specific gravity (density) and hardness. Like all forms of Beryl, Emerald is harder than Apatite, Quartz and Feldspar, but is slightly softer than Spinel, Topaz and Sapphire. However, they are generally more fragile than other Beryl’s, owing to their naturally included state.
