A shift in the color of the surface of metals like brass, copper or bronze develops when it is exposed to the air. This process is called oxidation and it happens over time. However, the same result can be achieved more quickly. Patina jewelry is often created by using chemicals and necklaces, bracelets, rings and earrings treated in this way are available from many online stores today.

It has been found through experimentation that different chemicals react with metals to create unique colored patinas in a short period of time. There are many variations in the colors produced depending not only on the metal but on the chemical and the method used. It is the variation of hues that offers so much potential in the creation of jewelry that is unique and full of character.

Reds, greens, browns, purples and blues can all be created by using various chemicals and techniques. For example, a chemical called Liver of Sulfur is used to turn silver to gray or black. A household chemical like ammonia can be used to create the most brilliant blues on copper. Vinegar and salt can be used to produce a verdigris effect that is like the patina on statues that have been standing outdoors for years.

Chains and other objects used in creating necklaces, bracelets, earrings and rings are painted, sprayed, immersed or heated to accelerate oxidation. As far back as the Middle Ages, copper was buried amidst dung to hasten the process. Today burying is still used but the mediums are sand, coffee, sawdust, tobacco and cat litter instead of dung. These are soaked with a specific solution to help the process along.

Designers often experiment to achieve a specific effect. The items they produce are unique and creative, adding one-of-a-kind appeal to an outfit. Chemical mixes are also available for purchase today that have already been proved to achieve specific results.

Designers are using many different objects and giving them all sorts of patinas that turn them into something special. From delicate teal colored butterfly earrings to an olive green leaf layered necklace, many items are suited to both formal and informal wear. The chains used in the necklaces and bracelets are also treated as are the ear wires on earrings to integrate with the look of the objects hanging from them.

It is important to make sure that these items are properly finished. Some of the colors are not stable and they continue to oxidize over time, darkening the color. Professional sealing is necessary to prevent this from happening and to make sure that the item is durable.

Patinas can create a completely different look and transform a fairly ordinary piece into something spectacular. The look does not appeal to everybody as there are those who love sparkle and shine. However, many do love these iridescent hues and will go out of their way to find special items. Fortunately they can find them at many online sources today and they take advantage of being able to compare items and prices to get the best deals.
