This is a vintage thick curb chain necklace. The length is approximately 40cm. The chain links are 3.3mm vertically and 2.1mm horizontally. The clasp is stamped with silver925 and sterling. Recently, many silver products are fake, with only silver plating. However, as you can see in the photos, this is vintage silver925, so you can rest assured. It is also called sterling silver. It would look great with a pendant or worn as a chain only. Vintage Thin curb chain Thick curb chain 40cm chain
