Our sterling wire is handcrafted for your next jewelry project. We start with 18 gauge Sterling wire, then we emboss it to give the beaded texture. The wire is roughly 1mm wide. Since the wire is half round, the back is flat. Variations will occur, since each wire is made to order. Our wire is great for earring loops and bezel embellishments. This 925 Sterling silver is in it's natural state, so it will tarnish. Please keep it in a cool, dry place and take care when handling. The wire is shipped in a small coil. Although extremely rare, some people are allergic to the metals and finishes commonly used in making jewelry. We cannot guarantee that our products are totally free of ingredients that may cause an allergic response in individuals who are sensitive and react to the ingredients in our products. It is the responsibility of the consumer to be aware of any allergies he or she may have to metals (gold, silver, etc.) or the oxidation applied to metals prior to making a purchase. If you have concerns about allergic reactions, you should discuss them with your doctor before wearing our products. Because there is no way for us to know the medical history of our customers, Silver Cypress Creations will not be held liable for any allergic reactions that may occur as a result of wearing our jewelry. 18ga7frrtrl21qttr
