Tarnishing

Tarnishing in sterling silver jewelry refers to the gradual darkening or discoloration of the metal surface over time.

Tarnishing and Oxidisation appears as discolouration on the Silver. It can look like dark marks, patches or even as if the Silver is coming off. It is a natural occurrence as Silver is a natural metal which is not man made like plastic. Tarnishing and Oxidisation are reversible and easily treated.

Tarnishing occurs when silver comes into contact with certain elements in the environment. The primary cause of tarnish on sterling silver is the metal’s reaction with sulfur compounds, which are present in the air, as well as in some substances like rubber, wool, and certain foods.

Silver in its natural state is a fairly soft metal so it’s combined with other metals, such as copper, at a ratio of 92.5% silver to 7.5% copper to increase its strength and make it more pliable. At Silvery we use the finest grade of silver, known as 925 Sterling Silver, for our jewellery pieces. While pure silver is resistant to oxidisation and tarnishing, when it’s combined with other metals, even in very small proportions, it is likely to react with oxygen or other pollutants in the air. This will result in a superficial, blackish coating forming on your jewellery. This is a natural process and does not damage the silver underneath. It’s reassuring to know that this thin layer is easily removed, restoring the item to its original sheen. 

The natural rate of tarnishing can be accelerated by high levels of humidity, air pollution,  sweat, perfumes, household chemicals, hairsprays, etc. 

The colour change or tarnishing of your Silvery item is a natural occurrence and not a manufacturing or quality defect. It can be due to the pH levels of the wearer’s skin which varies in all people. The second most common reason for tarnishing is exposure to soap, chlorine, saltwater, perfumes and lotions even in tiny amounts. Tarnishing can be accelerated by contact with tap water as it contains chlorine. As mentioned above, it is not a manufacturing fault or flaw. Some can wear items and never experience tarnishing, while others experience it almost instantaneously. 925 Sterling Silver is also a natural metal, so it reacts differently when exposed to skin or external factors.

Additionally, tarnishing can be related to a multitude of things that don’t necessarily present themselves as definitive culprits. With Silver being a natural metal, mined from the earth it is subject to reacting differently from one batch to the another which explains why one item might be perfectly fine and others react differently. As with most if not all things in nature it has a certain level of volatility.

Oxidisation is the process whereby the metal alloys within 925 Sterling Silver react with the natural air around us, it is much like tarnishing. Commonly understood as the “addition of oxygen”. It is advised that when storing jewellery over long periods of time it is best to do so in an airtight jewellery box or container to prevent this natural process from happening. Please note our Silvery boxes are not intended for long-term storage as they are not airtight.

With Silver being a natural metal as explained we are unable to offer guarantees against tarnishing or how items react. Tarnishing is not rust, it is important to understand that. It is a metal reaction related to external factors.
