4Ever Expressions are 09.25 Sterling Silver, necklaces, bracelets, pendants and findings are also 0.925 (92.5%) sterling silver. All silver will tarnish over time. The best way to prevent this is by wearing your piece of jewellery. When you're not wearing your piece, store it in an air tight bag with the anti-tarnish strip that's included in your box. The anti tarnish strip is a special absorbent paper that protects metal jewellery and other items from unsightly discoloration and tarnish. Each strip has approximately a 6 month shelf life.
4Ever Expressions has a Sterling Silver jewellery cleaner and polishing cloth that can be added to your purchase.
