Emerald in tumbled stones in a 200-gram bag Each bag of emerald in tumbled stones contains between 40 and 60 pieces, with sizes ranging from 1 to 2 centimeters. Emeralds are known for their characteristic intense green color, symbolizing nature, health, and hope. These tumbled stones come from Brazil, a country with a rich and diverse supply of gemstones.
