Reflecting the colour of spring, emerald is the birthstone for May. It is also a traditional gift for those celebrating 20th or 35th wedding anniversaries. Emeralds come in various shades of green, from deep darkish green to soft green, fine grass green and light green. Emeralds, which are from the beryl family of gemstones are relatively strong, registering 7.5 - 8 on the Mohs scale of hardness. While they are fairly resilient to knocks, they can be chipped or scratched. Most emeralds have inclusions (imperfections). It is extremely rare to find a natural emerald without flaws. That is why a top-quality natural emerald will often be worth more than a top-quality diamond of the same weight. One of the largest emeralds discovered is the Mogul Emerald, weighing in at 217.80 carats. It is about 10 cm high.
