If you wish to purchase this chain by the meter please click this link Tarnish Resistant Coating: This chain has been treated with a hypoallergenic molecular bonding process that will help your pieces resist tarnishing. It protects against in stock oxidation – UV rays while on display, while in storage and from customers trying on the pieces. This treatment will keep your pieces bright longer but still allow you to solder or chemically oxidize the chain. December 19 2022 Link Measurement: OD: 3.38×4.15mm ID: 1.81×3.10mm Link Wire Width: 0.51, 24ga Link Wire Thickness: 0.28mm, 29ga Recommended Jump Rings: What gauge open jump ring to use: Up to 14ga, 1.64mm Recommended: 5mm 18ga or 4mm 22ga If soldering / welding: 3mm 22ga, 3mm 24ga or 3mm 26ga These jump rings are specifically recommended for this chain style. The chain you’re attaching them to may have a different suggested size. How Dapped Chains Are Made: Dapped chains begin as standard machine-made chains, such as cable or curb styles. These chains pass through precision steel rolling stamps called dapping tools, which mechanically flatten—or “dap”—one or both sides of each individual link. This process adds a mirror-like shine or a delicate faceted texture, all without using cutting tools to shape the metal. Because dapping reshapes rather than removes metal, it preserves the surface integrity, an essential benefit for materials like gold filled. During production, the chain’s link dimensions may vary slightly, usually within ±5% to account for compression, stretching, or normal wire gauge differences. For instance, a 2.00 mm link may measure between 1.90 mm and 2.10 mm. As a result, some recommended jump rings may fit more tightly than others. However, the end link will always accommodate a 26ga jump ring. View Abbreviation Guide Tips, Tricks and How To's! Follow Stones and Findings on YouTube
