Silver 925 jewelry has a strong metallic luster, as well as showing the greatest surface reflectivity among all metal jewelry. Silver jewelry does not oxidize much when it is continuously exposed to air and water. You should only expect a surface oxidation to occur due to the formation of a thin layer of silver sulfide when silver comes in contact with sulfur in the atmosphere. For the creation of the jewelry, no pure silver was involved; but alloys that have improved properties. The most common jewelry alloy is sterling silver alloy which contains 925 parts of pure silver in a thousand parts of alloy. Long story short, silver jewelry should only blacken on the surface, leaving a stain on the skin which, however, you do not need to be concerned for allergies. Plus, it is easily washed off by both the skin and the jewelry without leaving a mark or damaging the jewel.
