"Powerful" varied shades of black Burmese jadeite bangle bracelet.  Size is 61 mm inside diameter, 15 mm wide.  Thick and heavy, strong enough to wear all the time. Very well polished all around.  Icy cold to the touch. The photo cannot show the wonderful Qi energy that makes this awesome.  Black jade is very protective.

Purchased while jade shopping in south China near the Burma (Myanmar) border.  Tested by refraction, genuine and natural Burmese jadeite grade A.
