Looks like a classic soft green Chinese jade bangle bracelet and the third photo shows the "hidden power" few veins of darker green "yang" to "hide" in the yin.  Size is 69 mm inside diameter, 13 mm thick.  Lots of jade in this bangle bracelet make it strong and durable for every day wearing.  

Photos taken in natural outdoor light at different angles so you can see how it looks all around.

Made by Ying Yu Jade carver in China from genuine and natural Chinese jade.
