I choose Argentium Silver because it is resistant to tarnish, and made with reclaimed silver. These are 22 gauge, formed with a urethane hammer, and polished to a mirror finish. The fish hook style hangers are gold-filled. They weigh 2.1 grams each, and measure approximately 0.4” wide (11 mm) by 1” long (25 mm). I cut silver blanks to make these, and use the same process each time, but please allow for very slight variations (I am definitely not perfect yet). I promise the same quality and mirror finish with each pair. The following description of Argentium Silver is courtesy of Rio Grande: Made with a touch of germanium, Argentium® Silver presents a bright white color that is closer to fine silver than traditional sterling, yet is highly resistant to firescale and less likely to tarnish under most conditions. It welds flawlessly and is ideal for fusing techniques. All Argentium is made from reclaimed silver and its sources are guaranteed by Argentium International Ltd. Your customers will appreciate the value and convenience of brighter-white sterling silver designs that resist tarnishing and keep on shining.
