Emerald is a rare and valuable gemstone and is known as the traditional birthstone for May, as well as the traditional gemstone for the astrological signs of Taurus , Cancer and sometimes Gemini.
Emeralds represent the month of May and is a green version of the mineral beryl. They have the most beautiful, most shiny and most glowing green that can possibly be imagined: emerald green. It is considered to be the talisman of the goddess Venus, and to represent faith, goodness and kindness; however, for that reason, MayÃÂs birthstone turned out to be an EMERALD.
Emeralds vary in colour from dark green, to light shades of lime mixture with white streaks. It is said that the emerald got its colour from the presence of pieces of chromium and vanadium, which replaces the aluminum in the mineralÃÂs structure. Due to this, the stone can change its colour slightly anytime if high-pressured heat is added.
The value of an emerald depends on its clarity from sharpness to the amount of white streaks it contains. Clear stones with dark vibrant colours sell for the highest price compared to emeralds that lost its colour due to heat. When the cuts of an emerald are sharp, they tend to be sold faster, than an emerald that is very smooth and gentle. Almost all emeralds contain exclusive flaws, cracks, and scratches, which can affect the clarity and the price in a negative way. The carats of different types of emeralds change, the higher the carat, the more it costs. Overall. the value of an emerald and how much it can be sold for depends on the emeraldÃÂs cut, colour, clarity and carat. If an emerald doesnÃÂt have all these properties, it wouldnÃÂt be that costly to purchase.
The sizes of emeralds differ due to the sizes of the rocks it is found in. The quality of the emerald doesnÃÂt depend on the size or weight but depends on the mixture itÃÂs made up of from the inside to the outside. An emeraldÃÂs shape and appearance can also state the price, the more unique the emerald is than other emeralds, the price will be higher.
The most rare and valuable emeralds can be found in the Muzo mine in Colombia since many of the rocks there, is full of varieties of minerals including the beryl. Fine emeralds, not that expensive like the antiquity ones found in ÃÂEgyptians MinesÃÂ and Austria can be found in many parts of the world including Zambia, Brazil, Zimbabwe, Madagascar, Pakistan, India, Afghanistan and Russia. Emeralds are very hard to find which means its very special when another emerald is discovered.
