Jewelry chain in 316 grade stainless steel. Hypoallergenic and tarnish resistant. Each link is roughly 3.5x4.5mm in size and 1mm thick (approximately 18 gauge). This chain is a shiny silver tone.
The links are soldered closed links with the soldered joint barely visible and hidden within the interlock to the next link. This is a really nice size for a charm bracelet.
