Hallmarked Sterling Silver Nurses Belt Buckles. Although not worn as much as they used to be silver nurses buckles are still the number one graduation gift for qualifying nurses. Even if they are not used they become a treasured keepsake for years to come. Our solid silver buckles are made in our own workshop and they are presented in beautiful cases. Please look at the sizes of the buckle. It is Length X Width but please note that the widest width is not always the width of the bar that takes the belt. To fit your belt to the buckle it is sometimes necessary to cut the belt on a taper so that it fits round the bar before stitching it into place.
