This mid-century bracelet was produced by RTA. I've had a few RTA pieces over the years, all based on Antonio Pineda designs, all of exceptional quality and craftsmanship.

Wears beautifully and feels luxurious on the wrist. Measures a closed, wearable length of 7". Width is 1 9/16"...

A nice pair of 14K yellow gold and ruby cufflinks, the round faces accented with engraved lines and a stippled finish that suggests a quilted design. The intersections of the engraved lines are set with round brilliant-cut rubies. The backs are marked "14K". We have seen matching cufflinks, set with rubies or with sapphires, stamped with Tiffany's retailer mark, so it's likely they were made by one of the higher-level Newark jewelers.

I have written in the past that Elna jewelry is more often than not very generous in proportions but this stunner of a bracelet goes above and beyond that! It is not just its sheer monumentality that impresses. It is also the classically "archaeological" character of the design itself which is expressed by the carved stone "mask" of an ancient Aztec Eagle warrior. Awesome in its military magnificence, the portrait is flanked by highly stylized butterfly (?) links with big cabochons set in bezels...
