About Products and Materials

Q. Can I shower with the jewellery piece on ?
Unless your jewellery is made of solid K gold with no gemstones attached, we do not recommend wearing it in the shower.
There are a couple of concerns:
1. The use of exfoliating or whitening ingredients in bathing products, or scrubbing with a sponge, can lead to surface abrasion and loss of luster on K-gold filled or electroplated metals. Additionally, repeated soaking and exposure to air can result in internal oxidation and fragility, causing your jewellery to become dull and prone to breakage.
2. In addition to concerns regarding the metal surface, many of OYJ designs are inlaid with gemstones. Each gemstone has a different hardness. The lower the hardness, the easier it is for dyes, pigments, oils, moisture, and impurities to penetrate into the cracks, leading to changes in color. At this point, it is impossible to restore them to their original state.
3. Some jewelry has tiny, hard-to-see gaps where soap and other substances may get trapped during bathing, making self-cleaning relatively difficult.
4. Many delicate designs may be damaged due to friction during bathing or accidental pulling.
Q. Will plating fade easily ?
Most of OYJ's jewellery are made of premium brass plated with thick 18K solid gold or finely plated with sterling silver. Depending on the design, we would add an extra protective layer over the plating surface. With proper wearing habits and maintenance routines, it is less prone to rapid discoloration or oxidation. A quick wipe with a soft cloth can promptly restore its brightness.
Gradual oxidation or discoloration is normal due to wearing over time. OYJ provides lifetime maintenance service, hence you can send your jewellery pieces back to us for refurbishment and re-plating. Please click here to learn more about metal maintenance recommendations.
If you expect to wear your jewellery every day, even during showers and sleep without taking it off, we recommend purchasing from our pure K gold collection.


Q. Why does it turn black even though it's not worn ?


The primary culprits for causing metal discoloration are moisture and airborne pollutants. Store your jewellery in a sealed container to avoid continuous exposure to air and oxidation. Keeping them dry in a ziplock bag is the key to maintaining the longevity of your jewellery.


That said, metal oxidation is a normal phenomenon, but the degree and speed of oxidation also varies. Gold and platinum are the most stable precious metals, with very slow oxidation reactions. 18K gold, which is mixed with precious metals, also possesses slow oxidation and non-discoloration properties, along with high hardness, making it the most suitable metal material for jewellery design.
