A piece from the opening years of the Los Castillo taller this is a simply stunning bracelet! Despite the almost minimalist design, the cuff is breath-taking with its huge black onyx cab that centers its face and glistens whenever the light hits it. The sterling frame has thick twist-rope accents while big fleur-de-lis motifs flank the stone. With an inner circumference of 6 3/4" (including the 15/16" gap), the bracelet is relatively adjustable but I would strongly advise to have your jeweler do it so as to avoid damaging it. Its width varies between 1 1/4" at center front and 1/2" at either end and it weighs 62.0 grams. Fully and appropriately hallmarked with the Los Castillo early signature as well as "MADE IN MEXICO STERLING" alongside des. no 304, the cuff dates in the 1940s and is in excellent vintage condition.
