I also have a 1 1/2 inch flexible mesh gold toned bracelet. It has similar markings that didn't quite make it entirely on the metal. It looks to be CT 18750 or CT 19750 along the outsides are slanted lines / & \ any clues what or who makes this. Very pretty gold color & shine. The botttom of the stamp did not make it all the way onto the edge of the metal so the bottom of the 8 or 9 is not on the metal. Please advise if possible. Thanks Dave & Debbie

rhombus and rectangle with pointed sides by: Anonymous
18ct is the minimum gold standard for sale in italy. but the rhombus doesn't seem to fit, since 1968 Italian maker's marks form changed to a rectangle with pointed sides and a five pointed star symbol added on the left.
in a rhombus, often called a diamond, all the sides are equal, the opposite sides are parallel and the opposite angles are equal.
