Two vintage Mexico Sterling crosses with Onyx from my personal collection of vintage crosses are featured on this double strand necklace. The bottom stylized cross is signed Mexico 925. The ornate upper cross is backed by a shiny teardrop of Onyx and signed S in a circle and hallmarked 925 for Sterling Silver. Each cross is 2" in length. The toggle clasp is Sterling. This piece has a wearable length of 18.5".
