Check out this tiny sterling silver (marked) abacus pendant which actually works! The pendant measures 3/4" H x 1/2" W x 1/8" thick. It has 9 fine rods which have teeny tiny beads which slide and a dividing vertical bar to the right side. It comes with a silvery chain which is marked "KOREA" which is most likely steel or lightly plated silver, but not Sterling. The pendant itself is marked "STERLING" on the back just below the bale and "Made In Hong Kong" at the base of the back. Most likely a souvenir item it has some age based on its wear--we think most likely from the 1960's. We will ship it to you in a small jewelry gift box for storage or gifting as you wish. Very charming little pendant!
