This antique diamond circle brooch is a versatile piece from the Edwardian era, circa 1915. The brooch features a garland or laurel leaf circular frame set with small round diamonds and four larger old European-cut diamonds. At its center, an open space houses a square frame filled with old square French-cut diamonds surrounding a straight line of round diamonds. With approximately 7 carats in total diamond weight, this platinum-set jewel can be worn as either a pendant or brooch thanks to the loop at its top.
