This Amethyst Star belly bar was made a few years ago now. Believe it or not the owner is actually a five star fan as in The pop group Five Star see fan club
The back of the piece which I don't have any pictures of is rounded to make it sit comfortable in the navel seating. The main stone is a 5 x 5mm round faceted with matching trillion or triangle cut points. The top ball is a 3mm round faceted to match.
Made from 14ct yellow nickel free gold.
