.925 sterling silver, also known as sterling silver, is one of the world’s most popular jewellery metals, and it is often sold in high-end jewellery stores along with gold, platinum, and other precious metals. Sterling silver is obtained by alloying .999 silver, or pure silver, with small quantities of copper, usually around 7.5 percent, to improve its durability. Unlike brass and nickel, .925 sterling silver is more hardwearing and preserves its color, luster, and heft for much longer, with the added bonus that its value increases over time — all these while staying relatively affordable for buyers.

However, sterling silver tends to tarnish over time. To prevent the tarnishing process, rhodium plating is used. Rhodium, which is a member of the platinum group of metals, boasts highly reflective qualities and a significantly stronger composition compared to gold. In addition to enhancing the durability of sterling silver jewellery, rhodium plating also increases its luster and light reflection, prevents scratches, and ensures it stays tarnish-free for longer. Moreover, rhodium plating prevents potential allergic reactions to sterling silver, making it safe to wear for everyone.

Please note that rhodium plating wears off over time, which will cause the sterling silver to show through. Any exposed sections may acquire tarnish, but this can be easily polished at home.


With proper care and regular cleaning, rhodium-plated .925 sterling silver jewellery can preserve its beautiful appearance over the years to come. Mild liquid soap and lukewarm water, paired with a soft, small brush, is the easiest way to clean and maintain Caterina Jewelry pieces. In case the jewellery is very dirty, leave it to soak in lukewarm, soapy water for 10 minutes before carefully rinsing. Pat-dry with a soft cloth.

Avoid using any abrasives or chemicals on your rhodium-plated sterling silver jewellery, such as silver dips and ammonia-based products. Also, don’t use toothbrushes or polishing cloths that are intended for use on uncoated silver or gold jewellery, and don’t place the jewellery in an ultrasonic cleaner.

ABOUT 18K Plated Gold

All Caterina Jewelry gold-plated jewellery is plated with 18K gold.

In its pure form, gold is extremely soft and malleable, and thus unsuitable for jewellery-making. In order to create jewellery that stands up well to daily wear, gold is alloyed with other metals to increase its strength and resistance.

Karat, abbreviated ‘K’, is used to indicate the percentage of gold in gold jewellery. For example, 14K gold contains 58% gold and 42% alloyed metals, while 18K gold contains 75% gold and 25% alloyed metals. The higher the percentage of gold, the more expensive the jewellery will be. 18K gold also has a deeper yellow tone compared to 14K gold.


While you may find that 18K gold-plated sterling silver jewellery requires a little more upkeep than 18k gold jewellery, there are a few simple ways you can maintain the color and luster of your Caterina Jewelry pieces and prevent fading. It’s especially important to avoid spraying perfume or applying lotion or cream while wearing your items so that they don’t interact with your jewellery’s metal. Instead, choose to wear your pieces after you have sprayed on your favorite perfume or after the lotion or cream has been absorbed into the skin.

Avoid exposure to substances like oil, nail polish, nail polish remover and chlorine, which may react with the 18K gold plating and cause it to fade more quickly. Moreover, remember to remove your 18K gold-plated jewellery before exercising to avoid sweat entering into contact with your jewellery.

In case the jewellery is very dirty, leave it to soak in lukewarm, soapy water for 10 minutes before carefully rinsing. Pat-dry with a soft cloth. Don’t use antibacterial soaps or jewellery cleaners, which may contain certain ingredients that will cause the gold plating to fade more quickly.

Stainless Steel

Stainless steel is one of the strongest metals used in jewellery-making. It is usually distinguished by its silver sheen and excellent durability, which make it ideal for those with very active lifestyles, such as athletes and gym-goers.

Steel contains carbon, nickel and chromium. For it to be considered stainless, at least 12 percent chromium must be present in its composition. Chromium adds an invisible top layer that prevents rust and corrosion; as such, stainless steel jewellery will not rust or tarnish.

Stainless steel jewellery is significantly more durable than sterling silver or gold jewellery, which means it can withstand more tear and wear, making it highly appropriate for athletes and people who lead very active lifestyles. It also requires little maintenance, and as the nickel in stainless steel is tightly bound and won’t leak out, therefore making it safe for those with metal allergies, too.


Stainless steel jewellery requires little maintenance compared to rhodium-plated and 18K gold-plated sterling silver jewellery. Pour warm water in a small bowl and add a few drops of mild dishwashing liquid. Use a soft, lint-free cloth to gently wipe the stainless steel jewellery with the soapy water until the dirt and grime is removed. Make sure to rub the item along its polish lines in order to preserve its luster and high-shine polish for longer. Once clean, wipe the remaining soap using a moist cloth dipped in clean lukewarm water and leave the pieces to air-dry on a clean towel.

You may choose to use a jewellery polish or polishing cloth to shine it. Alternatively, toothpaste can be used to clean any dirty spots on your stainless steel jewellery. However, it’s important to choose a non-whitening brand that doesn’t contain silica and use a soft cloth to clean the jewellery. Rinse your pieces thoroughly once clean, then leave them to air-dry on a clean towel.
