Anodic oxidation on silver jewelry -- the so-called anodic oxidation treatment in the most direct way is to plate the jewelry with a very thin layer of white alumina. This treatment is being used wildly on silver jewelry now.
a. What is 925 silver
Generally speaking, the sterling silver jewelry sold in the market is made of 925 silver instead of 999 sterling silver. 925 silver is a kind of alloy which combines 7.5% of other metals and 92.5% of silver, and it is internationally recognized as sterling silver. The jewelry made of 925 silver is stronger and more durable. Compared with the jewelry made of 999 sterling silver, the jewelry made of 925 silver can keep its shape and does not deforms easily, at the same time, the surface of the jewelry will not wear too much or need constant polishing.
b. How to maintain sterling silver jewelry
The biggest reason that leads silver oxidation is the oxygen in the air, so the best way of maintenance is to use air barrier, for example, silver jewelry should be put in a sealed plastic bag and then into the jewelry box, blocking air contact with the silver. When silver jewelry is oxidized, silver polishing dip (SP dip) or silver polishing cloth (SP cloth) can be used to polish the jewelry.
