Old vintage sterling silver turquoise watch band. The 2 turquoise sterling end pieces have no marks whatsoever but did test for sterling. They measure 1 and 3/4 inches long - end to loop end. The 2 turquoise cabs in each piece are pave set.
The "spidel" type band opens to 2.5 inches wide if you really stretch it beyond it's 2" closed condition. That stretch band is NOT sterling. Each little link is stamped USA. The whole thing weighs 18.2 grams.
