This is a very hard to find and wearable hinged bangle bracelet made by Antonio Pineda in Taxco, Mexico circa 1960's.  Measuring 1" width and weighing a heavy 122 grams, this substantial 970 silver bracelet is stamped with Pineda's crown maker's mark, design number "ZZ 633" and marks for silver content and Mexico.   This fabulous bracelet will fit a small to medium wrist, with interior measurements of 2.25 x 2.00".  There is uniform wear to this bracelet with little nicks and dings throughout, as is expected with a higher content silver piece of this age and weight.  They could be polished out but we do not recommend it--leave the bracelet with its historical fingerprint and add yours!
