This unique wall art was a gift so I don’t have a lot of details on it. I believe pieces of sea glass, shells, & rocks are adhered to glass within the frame. There have always been minor imperfections in the frame, I assume to give the piece a weathered “beachy” look. It hangs on a gold ribbon (which could be changed to suit your taste). Great piece if you like the ocean or lakes - or to give as a gift. Additional approximate measurements: frame is 5/8” deep & because of the shell the piece is 1” deep. Last picture is of the reverse side.
