1 1/8” diameter with toothed border and central projection surrounded by several leaf-shaped forms, each with a lower projection within. The choice of seven segments has spiritual significance. 7 has been considered lucky by various cultures from at least the seventh century BC. Roman history/mythology reveres the Seven Kings of Ancient Rome (753-509 BC). The use here likely relies on a combination of the positive supernatural qualities of the number and there is no indication that the luck it brings is in any way diminished! Professionally refurbished with a silver overlay restored and mounted on a Sterling silver neck chain for modern wear. Gift boxed with certificate of authenticity.
