Over time, jewelry can accumulate body oils and residue from skin products, which may affect the appearance of the mounting and the stones. To maintain the brightness and freshness of your jewelry, follow these simple steps:

1. Take a soft-bristled toothbrush with a mild soap and gently brush both the front and back of the stones and metal.
2. Rinse the jewelry thoroughly with lukewarm water to remove any soap residue.
3. Avoid using ultrasonic cleaners, as they are not recommended for jewelry cleaning depending on the stones.
4. Steam cleaning is an effective method, but exercise caution with emeralds or opals, as high heat can potentially damage these stones.

By regularly caring for your jewelry in this manner, you can help preserve its beauty and extend its lifespan.
