Our 925 Sterling Silver Products is Finishing With Silver Plated (AND / OR) E-coat...Silver Plating is an extra 100% Silver layer that we apply on top of the solid silver base in order to give it long-term shininess and an extra protection against scratches and daily usage.....E-coating, also known as electro-coating or electro deposition, is a method that uses electrical current to coat a metal surface with an organic lacquer, covering every nook and cranny on the jewelry with an even and consistent protective coat. This coat protects the sterling silver used to create the jewelry and lets the natural beauty of the sterling silver come through without fear of damage. Basically it is an ultra-fine transparent layer of plastic that protects the Silver and it's plating, therefore considerably increase the lifetime and the shininess of your jewelry....Oxidation is a chemical process which gives a "tarnished" or "discolored" effect to your jewelry. Oxidized jewelry is getting more popular along with other products having antique finishes or vintage effects.
