Classic round Burmese jadeite "old mine" bangle bracelet.  Size is 58 mm inside diameter 10mm thick.  Rare "good green" color and lighter green make it endlessly interesting.  Very well polished all around.  Very high "chime" indicates the jadeite is best quality.   Mined and carved prior to the 2000, this was purchased during Ying Yu Jade shopping trip in China near the Burma (Myanmar) border..
