We are offering design 263 which is one of the early Los Castillo pre-Columbian swirls. The matching cuff shown is also available on my site. The necklace is one of the most magnificent Los Castillo designs and this one is 17.75 in. which makes it fit nicely as most are very short in length. This is properly hallmarked with the old linear Los Castillo hallmark. There are many copies out there but this one is genuine and a pre-1948. It moves like a slinky with the rivets that hold the links together for strength. The beads are not dented and the weight is 206 grams heavy. A big presence is shown with 1.25in. in width. Dress it up or down, it goes with anything, just LOOK AT THAT NECKLACE!
