Vintage Mexico Sterling Silver Hi-Shine Modernist Torque Collar Choker Necklace

Nice in the pics, but striking when worn. As the light plays over the highly polished surface, the reflection seems to flash the light back out. 3 bands are fused together at the terminals & gradually flare towards center. Measures approx. 12" end-to-end on the interior (wearable length) plus a gap of 2 3/4". My neck is 14" & this piece is borderline too big for me. I think it would be just right for someone with 15-16" neck, but not much more than that. There's enough flex in the silver to adjust the fit but NOTE: warm the necklace in your hands or some warm water for a couple of minutes before adjusting- this way you can avoid developing stress cracks in the sterling & compromising its strength. The necklace has a partial stamped mark on the reverse. Under my loupe, I can make out what looks to be "TC-" and underneath that, the partial letters "exi". The collar tests as sterling & weighs 42.7 grams. In very nice vintage condition.
