EmeraldOne of the four âpreciousâ stones. An intense, deep green is the most desirable colour for emeralds. Flaws and cloudiness (âjardinâ) are very common in emeralds, so stones are often oiled, irradiated, and dyed to improve their look. Synthetic emeralds have fewer imperfections and are hard to set apart from natural stones. Emeralds belong to the beryl… diamondA precious, lustrous gemstone made of highly compressed carbon. Diamonds are one of the hardest materials known to mankind. Colours of diamonds range from colourless, yellow, orange and brown to almost black. Natural coloured (or âfancyâ) diamonds can be extremely rare. The cut, colour, clarity and carat weight of a diamond are the criteria jewellers use… earrings are hard to find, especially the pretty ones. These earrings are gorgeous on, and the emeralds are a good colour.
