There are many varieties of colored gemstones. One of the most popular is the EMERALD, a deep green stone that is harder than quartz and softer than ruby, sapphire, or diamond. The highest quality emeralds come from Colombia. As gemstones are often a significant investment, it is very important to know how to choose high quality emeralds before you decide to purchase them.
1- INSPECT THE GEM’S COLOR
A true emerald is deep green.
2- CHECK THE STONE CAREFULLY FOR CRACKS OR INCLUSIONS
True emeralds are very strong stones. Small inclusions in an emerald are acceptable because they can make an emerald unique! Inclusion occurs when a foreign material that is not actually a part of the gemstone is inside it and they can be solids, liquids, or gas.
3- LOOK AT THE STONE THROUGH A MAGNIFYING GLASS
This will allow you to see imperfections that are not visible to the naked eye.
4- CHECK FOR TRANSPARENCY
A high quality emerald may be a bit cloudy, but should have a significant amount of transparency.
