I'm probably not the only one who has accumulated a rhinestone here and a chain there from broken jewelry over the years. Oftentimes, I just store broken pieces that I believe have potential to be re-worked in the future in a junk box. Today, I re-worked a broken vintage rose brooch and a cuff that my sister made for me. The brooch was tarnished and the pin backing was all mangled. After ripping off the pin backing with pliers, I sandpapered the surfaces of the cuff and the pin that I wanted to glue together. The roughened surfaces takes the JB Weld material better. JB Weld is a very easy-to-use cold welding technique, and works by thoroughly mixing equal portions of 2 pastes together. Mixing the two together sets off a base-catalyst reaction. To do the mixing, anything disposable is good to use. I used a tongue blade (thick popsicle stick) here. Finally, I applied the mixed paste to both surfaces, and let set for 6 hours. Bam! There you have it--a simple project to re-vamp your broken and neglected jewels with the super easy cold welding technique. If this DIY were any easier, it'd be a crime. Can't wait to wear this with a stack of other cuffs and bracelets!
