Large and gorgeous vintage Retro period 14K Gold Brooch in the form of an open Swirl or Pinwheel. A sparkly Diamond is set into the center of the Swirl. The Brooch measures 1 1/4" in diameter and is of substantial weight (approximately 6.1 pennyweights, which is equal to 9.9 grams). The Diamond has an approximate weight of 10 points (not removed from the mounting to weigh). This is a gorgeous Pin (Brooch) which if one wished to be a Pendant, could have a jeweler add one or two links to the open work linear gold swirl and attach chain and a spring ring. It would be just as stunning as a Necklace or a Brooch. The piece dates to circa: 1940. It is marked 14K on the safety catch. It is also marked on the reverse center: 14K, Pall, a maker's mark or other mark that we can not make out, plus a presentation engraving: E.E. 1948. The Brooch is in very goo condition with normal scratching to the surface of the Gold Swirl under magnification. The vintage Retro Diamond and 14K Gold Brooch is prettiest in person and shows well in the photographs. Photos taken with and without a camera flash.
