Largest and oldest signed Miracle piece I've ever had, either in my shop or my personal collection. Approximately 2 1/2 inches in diameter, set with a HUGE foil backed imitation cairngorm center stone, and various other glass keystone shaped imitation stones in an antiqued finish silvertone setting. There are a couple of small points of foil loss on the center stone, but it doesn't seem to detract from the appearance of the stone. Looks very much like the classic Victorian Scottish agate pins. Pin fastens with a modern style safety catch and has an additional safety chain with pin for extra security for this heavy brooch.
