Plug is nice and heavy. Solid metal, smooth, well-made. The jewel seems securely attached. There's no reference of size online, but the plug is slightly bigger around than a quarter and the Jewel is closer to a fifty-cent piece. Customer service contacted me shortly after ordering to ask what color of jewel requested and shipped it promptly. The plug comes with a nice black bag for storage. Wife did love it........and that's what I was after!
