Resembling miniature clamper bracelets and almost always crafted using similar designs by pass rings fascinate me! All this detail in such a small space is definitely a feat of the Taxco maestro and the fact that they are adjustable makes them even more attractive. It occurred to me recently that by pass rings could be construed as another version of the "toi et moi" rings, the first example of which seems to have been offered by Napoleon to Josephine at the end of the 18th c.. Not as "delicately romantic" as their European counterparts, Mexican by pass rings are statement makers, bold and beautiful and not for the faint of heart. The juxtaposed serpents adorning the example at hand, universal symbols of fertility and the power of life and regeneration, have been magnificently rendered, their detail enhanced by the patina of time and the love of their previous caretakers.
Currently a sz 8.5 US (yet adjustable, upwards)the ring has a face approx. 1 1/8" by 3/4" and weighs 3.7 grams. It is signed with maker's initials "CS" as well as "TAXCO MEXICO STERLING" and a partially stamped Eagle assay mark. It dates in the 1950s-60s
and is in excellent vintage condition with great detail in the rendering of the serpents, great patina and no damage or repairs noted.
