I've had many nice, vintage links, but must say that the overall effect with these puts them among the nicest-looking, most subtle-yet-striking look of any of them..... Possibly Edwardian or perhaps somewhat later, definitely vintage, in Sterling (so marked) and with either black enamel or onyx panels. I liken the brilliance of the incising work to 'brilliant cut' crystal. Just magnificent and, no matter how I tried with the three photographic lights, the effect couldn't be captured/conveyed via the photos. Toggles work fine. 3/4" x 9/16" NOT real anxious to let 'em go....but, offered at $75. *** NOW $59. *** shipped to the CONUS. (Elsewhere, please inquire.) - Offer is subject to a change-of-mind, without prior notice !
