Sigi Pineda rings don't come up very often and I am very happy to present here an example out of his "boomerang" line. Fashioned in the so-called by pass style, this is a slick, mod piece, its two wings adorned with bezel set turquoise cabs. Fantastic patina and excellent vintage condition make this an absolute must-have for collectors of Mexican jewelry and lovers of mod design alike. Relatively adjustable (upwards, I would suggest), the ring is now a sz 6 and its face measures just above 1" by approx. 3/4". Dating in the 1950s-60s period, it weighs 6.1 grams and is signed with Sigi's name as well as des. no 47 and a partially stamped Eagle assay mark.
