Reworking antique chains is a favorite part of my jewelry work. Antique links are unique and special but don't always work well with modern jewelry. I've reworked this antique 9KT English chain of 21 inches to include a large and very versatile antique bolt ring clasp. The clasp is large at 16mm and opens with a nice snap. It can hold several charms or pendants or none at all and is very good looking as well. Matte 14KT Gold. Chains like this one are very versatile whether worn alone or in a layered look. 14.2 grams 9KT Chain. 14KT bolt ring clasp.
