Emerald is one of the four recongized precous gemstones, along with ruby, sapphire and diamond. It is also the official birthstone for May.

Emeralds can be found all over the world but the two main sources are Colombia and Zambia.

Emerald is the only precious stone that the clarity and colour can be altered with treatments.

GRS, Gubelin, SSEF & AGL are generally the most common choices when it comes to gem stone reports.
