How to best care for your jewelry


Silver & Gold

All our jewelry is made of 925 sterling silver and plated with either white rhodium or 18 karat gold.

Since our gold-plated jewelry is coated with gold, the silver will become visible over time if the gold plating wears off.

Unfortunately, it is difficult to predict how long the gold plating will last. It largely depends on how often you wear the jewelry, where on the body the jewelry is placed, and what the jewelry is exposed to.

We strive for the best possible quality in the gold plating, and if you feel that your plating has worn off too quickly, you can read more about how to make a complaint.

You can read more about how we manufacture our jewelry here.

Stones, Pearls & Diamonds

We use various gemstones and natural stones such as freshwater pearls, raw diamonds, tourmalines, and sapphires.

Because these stones can break if they are hit, we recommend that you take off your jewelry when doing sports, physical work, etc. Because natural stones are a natural material, they can vary in color and shape. Therefore, a stone may look different from the product images.

Jewelry Care

You should never store your jewelry in the bathroom because moisture can cause rapid oxidation.

When you need to store your jewelry for a longer period, we recommend that you put them in the sealed bag, which you will find in the jewelry box we sent you along with your jewelry.

To keep the jewelry in the best possible condition, we recommend that you take off the jewelry when bathing, doing sports, doing physical work, and other activities that expose the jewelry to moisture or impact.

Avoid getting chemicals from perfume or cleaning agents on the jewelry, as this will make them last longer.

Cleaning Your Jewelry

Step 1:
Mix some dish soap in lukewarm water. Do not use soap on pearls, as they are particularly delicate.

Step 2:
Place the jewelry in the water for 4-5 minutes.

Step 3:
Use a soft brush, such as a toothbrush, to clean under the stones or use your fingers to rub the jewelry.

Step 4:
Rinse the jewelry in the water and dry it with a clean, soft cloth. Do not use paper as it may scratch the jewelry.


Silver can oxidize, and in some cases, the silver will become visible through the gold plating, causing discoloration. You can use a silver polishing cloth and gently rub the area until the discoloration is gone.

If your jewelry shows signs of extensive oxidation, we recommend that you dip the polishing cloth in a little silver polish and rub the area until the discoloration is gone. Avoid dipping the jewelry in the silver polish as it may damage pearls, rubber, stones, etc. After cleaning, rinse the jewelry in water to remove excess chemicals.
