Emeralds are cut in the mining countries, and in Jaipur
(India) and Tel-Aviv (Israel).
This precious stone is one of the most difficult gemstone to cut because of the many inclusions and color zonings.
When choosing an emerald, the most important factor to consider is color. The more vivid the green, the more valuable the stone. Attractive bright stones with a lighter green color are in this moment in fashion. Darker green emeralds with a rich color may also produce very attractive pieces.
Oiling makes fissures less visible. Avoid emeralds with fissures which go deep into the stone, because it makes the stone very sensible to accidental shocks.
