Based on an Antonio Pineda design this Mexican modernist silver necklace by Cheo I would go as far as to describe as "industrial"! The oblong sterling links and the concave oval connectors are characterized by strong geometry and have an intense "utilitarian" vibe about them. And the opaque green "onyx" glass bars they encompass mirror that "no fuss" attitude. Cheo is one of those workshops we don't know much about but I have seen their work several times over the years...

The rivets allow the circular pieces to move as on a hinge, and each is connected at an angle to accommodate a comfortable fit on the wrist. The box clasp is sturdy and secure, with a figure-eight safety catch. Although the circular elements are hollow, the bracelet has a good heft and has a Constructivist aesthetic. It is probably from the 1970s. The clasp is marked 925 for sterling silver...
