Based on an Antonio Pineda design and simply marked with Eagle 3 assay mark (which Antonio also used), a modernist sterling silver and chrysoprase necklace and bracelet set from Taxco's middle period, around 1960. I believe the demi was probably made in Antonio's taller by one of his maestros after hours and its quality and level of craftsmanship bespeak its creators mastery over his art. Substantial yet comfortable to wear, both pieces boast the same wavy silver work that gently hugs semi-translucent chrysoprase cabs. The necklace is 15" long (wearable; inner circumference, clasped) by just shy of 3/4" wide and weighs 104.1 grams while the bracelet is 7 3/8" long (wearable) by just shy of 3/4" wide and weighs 69.5 grams bringing the total weight for the set up to 173.6 grams. Both pieces are signed with Eagle 3 assay mark as well as "TAXCO MEXICO 925". The set dates in the 1960s-70s and is in excellent vintage condition with hefty, stunning presence, gorgeous color in the stones that glisten because of the tiny little sparkling specs in them, patina to die for and no flaws noted.
