Sterling silver

consists of 92.5% silver, and the remaining part is copper. This is the reason why sterling silver is popularly referred to as "925 Sterling Silver" or just 925 Silver. Silver needs to be combined with other metals because it is very difficult to make great designs with just pure silver, which is soft and malleable.

A bit of hardness has to be introduced, by adding other metals such as copper or brass. That’s why jewelers are capable of making intricate and complex designs with 925 sterling silver.


Polished Brass goes through extensive hand polishing to give it a smooth, shiny finish.

Polished bronze goes through extensive hand polishing to give it a smooth, glossy finish. 

  • Bronze consists of 10% tin and 90% copper. A safe, transparent nano-coating is added to the surface in order to protect your products from tarnishing. However, over time and wear, the bronze will still naturally tarnish.

Brass Plated Metals are cast in Brass before going through extensive hand polishing to create a smooth surface texture. After being cast, we under-plate the brass with a tin-rhodium alloy to provide strength and durability. They are then plated with .25 microns of 14k Gold/Rose Gold/Rhodium. The outcome is a beautiful shiny luster with a high level of detail and smooth surface finish. For additional protection against wear and tarnishing, a very thin layer of nano-coating is added on top of the precious plating. Note that this nano*-coating will rub off with time and wear.

  • The tin-rhodium and precious metal electroplatings are about .25 micron each.


In order to preserve the finish on pieces, I recommend storing them in the original bag, or a cool, dry place. I do not recommend wearing brass plated jewelry to swim or exercise.
Silver is soft, so scrapes and scratches are to be expected as a normal part of wear. To minimize damage and ensure your product lasts a lifetime, I recommend storing it in the soft cloth pouch and away from other products. Avoid exposing the product to household chemicals during cleaning as they can be damaging to the finish. Use the silver polishing cloth to maintain a glossy surface.
Brass Plated Metal is a durable material, but can still scratch or wear through. Prolonged surface wear can rub off the finish. To prevent damage, I recommend storing your item in a soft cloth pouch away from other products, and avoiding exposure to household chemicals and cleaning products. Repeated exposure to water will also rub off the finish.

Pure silver is not susceptible to tarnish in a pure oxygen environment.  However, the copper that is contained in 925 sterling silver may react to the ozone and hydrogen sulfide in the air and cause sterling silver to tarnish.  Perfumes, hair sprays, and profuse sweating can also cause a quicker formation of tarnish.  

You won't be able to 100% prevent tarnish from forming, but there are a few ways you can significantly delay the formation of tarnish. 

The best way is to wear your sterling silver jewelry frequently.  The oils in your skin will "clean" the sterling silver every time you wear a piece. 

Another way to delay tarnishing is to store sterling silver in an airtight container, preferably with an anti-tarnish strip (a specially formulated material that absorbs moisture).  Anti-tarnish strips are available on Amazon or your local Walmart store.

While it may not look pretty, plastic zip-top bags are the best container to use to store your jewelry.  A jewelry box with a tight-fitting lid is also a good option.

A great way to clean tarnish off silver is with dish soap. Form a lather with your hands and rub the tarnish off your silver.
