Short answer: None. Emeralds can be refined into beryllium, but they are not "refined" into gems. Long answer: Asuming you're asking how many emeralds are cut into gems each year. This would be tons, but getting an exact number is not easy, as emeralds are mined in several locations and many mines. X number of stones are mined from one mine, but X number of stones are removed from the mine and thrown over the fence... the second number might be equal or greater than the first. Many stones are brought to market outside the usual production channel. Some are mined in one country, cut in another, shipped to a third, and sold worldwide. The black market is significant. You could compile a number from published production records, or perhaps trade magazines have researched it, but nobody will ever really know the exact numbers.
