Sterling Silver 925 ROSS SIMONS 18k Yellow Gold Vermeil Designer Signed Necklace Pendant. Weighs 3.5 grams. Just under 1" in length. Measures 15/16" × 3/8" wide. NWOT. ✨️RS vermeil is a thick layer of solid gold over sterling silver. Specifically, that layer must be at least 2.5 microns thick. RS vermeil jewelry is always crafted using 18kt gold – the highest karat offered in the market. Because of this substantial gold layer, these pieces exude a long-lasting shine and are less likely to tarnish with regular wear.
