Gold is one of the least reactive chemical components. In its pure state ( 24k/999 ), it does not react with oxygen, so it retains its color and shine. It is too soft for jewelry making, so it is combined with other metals to obtain higher strength alloys, the most commonly used being 14k (585) and 18k (750) gold. 

In general, the other materials that make up the alloys are silver and copper. That's why even gold jewelry can acquire an oxide layer, although much thinner than in the case of silver.

Oxidation occurs from the contact of oxygen and sulfur in the air with moisture. Depending on one's lifestyle and how they are stored, even gold-based alloys can acquire a fine layer of oxide due to the other components, generally silver and copper. The process is much slower, and the oxide layer is thin and self-cleansing with wear.

Gold can be damaged by cosmetics that contain solid metal particles. These are abrasive at the micro level and slowly grind away the surface of the jewelry, especially affecting the yellow gold plating.

Perfume, body lotions, sweat and air pollution are factors that chemically react with precious metals. Heat and humidity accelerate the process, and a combination of several of these factors is a simple explanation for the oxidation of silver and sometimes even gold jewelry. It is not an instantaneous process, but occurs gradually, especially when the jewelry is not worn regularly.

Silver is a soft material with the potential to oxidize if used improperly. The deterioration of silver occurs both spontaneously, for example in contact with perfumes, and gradually, if the jewelry is left in air and moisture or on chemically treated surfaces.

Fortunately, the oxide is a layer that is deposited on the surface of the metal and does not affect the metal in depth. Cleaning it is a simple operation that can be done in our showroom.

Lisa&Co jewelry plating is made with one micron of gold, which makes them resistant over time. However, if you choose to wear plated jewelry, be aware that it requires more care to maintain its color and that it will fade over time. The type of jewelry, the way it is used and the PH of the skin greatly influence the behavior of the veneer.

Rhodium plating is much more durable than yellow gold, but it doesn't hurt to treat it with the same delicacy. The recommendations for use remain the same, to keep the jewelry in the best possible condition. Don't forget that white gold jewelry is also rhodium-plated for a bright, shiny and precious look.

However, if you're looking for a piece of jewelry that you'll never take off, we recommend choosing one with rhodium plating. It is used on the surface of silver, although it does not change its color, to protect and prevent oxidation, and it will stand up much better to heavy wear.

We do not recommend using abrasive cloths to polish plated jewelry, as they are strong enough to clean the plating as well.

When you are not wearing them, it is best to store them in a box with an anti-oxidation lining that you keep closed.

Before storing, we recommend wiping your jewelry with a fine cloth (such as an eyeglass cloth) to remove traces of cosmetics, sweat or oils taken from the skin.

Organic pearls, when immersed in water, are porous and continue to interact with their environment even after they are harvested. Wearing them occasionally is beneficial as they can absorb the natural oils secreted by your skin throughout the day. If pearls come into contact with cosmetics that have not been absorbed by the skin, oxidation from gold and silver can transfer onto the pearls in the areas where the two materials touch. If this occurs, simply wash the affected area with water and a gentle soap.

It is recommended to wear pearls after applying any type of body lotions, perfumes, or skin treatments, and to wait until these products are fully absorbed before putting on the pearls. Pearls can be affected by chlorine, salts, and exposure to sunlight, which can dry them out. Avoid exposing them to pools or the sea.

After wearing, wipe the pearls with a soft cloth to remove traces of sweat, perfume, or dust for better maintenance. It is advisable to store them in a separate compartment of your jewelry box or in an individual pouch to prevent scratching. We recommend restringing pearl necklaces periodically, depending on how frequently they are worn. The silk thread we use is slightly elastic to allow the pearls to move and to better withstand tension. Over time, with frequent wear, it may not return completely to its original shape and can stretch.
