|1.||Why is it 925 Silver‚ not Pure silver?|
Fine silver (99.9% pure) is generally too soft for producing functional objects; therefore‚ the silver is usually alloyed with copper to give it strength‚ while at the same time preserving the ductility and beauty of the precious metal. Other metals can replace the copper‚ usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity‚ eliminating firescale‚ and increasing resistance to tarnish.
|2.||How to care your 925 Sterling Silver Jewelry? |
Store your sterling silver jewelry in tarnish prevention cloths or bags. The treated cloth slows down the tarnishing process and keeps the jewelry from rubbing against harder jewelry that might scratch it. Try to keep your sterling silver jewelry in a cool‚ dry place.
|3.||How to clean your 925 Sterling Silver Jewelry?|
Polishing cloths are an excellent choice for cleaning your sterling silver jewelry. You might read recommendations to use toothpaste to clean sterling silver‚ but avoid doing that -- toothpaste is abrasive and can leave scratches.
|4.||What is Sterling Silver Patina?|
Sterling silver jewelry that is worn continually often develops a lovely patina‚ a kind of glow combined with darkened areas. If you like the look‚ leave it alone. If you prefer a bright and shiny look for your sterling silver‚ use a polish cloth to restore the jewelry to its original appearance.
|5.||What is Rhodium? |
Rhodium is a rare‚ silver white‚ hard and chemically inert transition metal‚ and a member of platinum group‚ that has a high reflectance. Rhodium metal does not normally form an oxide even when heated‚ giving a timeless reflective white surface. See more details at wikipedia.
|6.||Why Rhodium is plated on Sterling Silver?|
Sterling Silver with Rhodium plated is often for tarnish resistance. Highly polished sterling silver is very white and brilliant. However sterling silver is a much softer metal than rhodium and with little wear accumulates many tiny scratches. As the surface wears it will no longer be smooth and highly polished. The brilliant finish will become dull. This is the natural characteristic of unplated sterling silver. Therefore a rhodium plated sterling silver will retain its original appearance longer that a natural sterling silver.
|7.||Why is my rhodium-plated sterling silver jewelry magnetization?|
A barrier layer of nickel is usually deposited on silver first. In this case‚ it is not to prevent migration of silver through rhodium‚ but to prevent contamination of the rhodium bath with silver and copper‚ which slightly dissolve in the sulfuric acid usually present in the bath composition. With this nickel layer‚ it creates the magnetization.
|8.||Where is the 925 Sterling Silver trademark?|
