This is a magatama (comma-shaped jewel) with a matcha green color on its back, and a translucent, creamy yellowish-green hue. I received it from a collector of Itoigawa jade magatama. There were other magatama of the same shape, but this one had the most unique color and translucence, so I chose it. Apparently, this color is quite rare. It's about 2.6 x 0.8 centimeters. #Hai'sMagatamaForSale
