Sterling Silver contains at least 92.5% pure silver and is alloyed with copper.

Argentium® Sterling Silver contains at least 92.5% pure silver and is alloyed with germanium, which has dramatically better tarnish resistance than standard sterling silver and requires minimal maintenance. An occasional wash and rinse and/or wipe with a soft cotton cloth is all that’s needed to keep the silver in pristine condition. No polish is required, and Argentium® Sterling Silver will remain beautiful and tarnish-free for years.

14k Gold Filled (or 14k Rolled Gold)

14k Gold-Filled is a hollow tube of 14K gold that is filled with another metal, usually one closely matching in color, such as brass. The exterior of the gold filled jewelry is solid 14k gold and everything you can see or touch is a solid layer of 14k gold. This tube of 14k gold is approximately 100 times thicker than gold plate. It is made by bonding with heat and pressure – with normal wear and tear the heavy 14k gold layer will never tarnish, chip or wear off. By law, this layer of 14k gold must be at least 1/20 of the total weight of the metal portion of the piece of jewelry. 14k Gold Filled items look and last like solid 14k and are considered life-time products, passed along from generation to generation.

In the USA, this process is referred to as “gold filled.” In Europe, the same process is called “rolled gold.” Both terms are synonymous with each other. Many jewelry purchasers outside the jewelry trade mistakenly think “gold filled” is the same as “gold plate.” Gold plate is a thin coating of gold chemically adhered to a base metal, and does wear off after a period of time. The only plated products we ever use are the chains included as free gifts with our pendants. WyreWorks yellow and rose gold filled jewelry creations contain ONLY high-quality 14k Gold Filled wire. Our gold filled and silver jewelry is made to last through generations and each piece is guaranteed for life against any defects in materials and workmanship.
