These pendants were cut from 20 gauge fine silver. Fine silver is 99.9 percent pure. These hearts are cut then soldered together, the center heart is cut from a pancake die in a hydraulic press, the outer heart is hand cut by me so no two will be alike. These have a sterling silver bail and will come to you gift boxed on an 18 inch Prince of Whales chain. There are two of these available at this time.
