Three circular layers of white, pale blue and rose acrylic, secured with eight silver rivets. The top layer is embedded with 15 silver round titanium rivets the same size as the external secured rivets. The semi-circular cavity contains various geometrically shaped metal pieces, mother of pearl and acrylics. There is no metal pin, but two dots of clear glue on the back.
