su Jewelry uses K18/K10 and Silver925.
[K18・K10]
Both K18 and K10 are resistant to discoloration caused by sebum and sweat, but exposure to air can lead to tarnishing. To maintain jewelry worn for extended periods, rinse it lightly with water and wipe with a soft cloth. When storing, place it in a jewelry box or a sealed bag. Avoid abrasive agents; if cleaning is needed, soak the jewelry in lukewarm water with a mild detergent for about 10 minutes, then gently wipe with a soft cloth. While both 18K and 10K are materials less prone to metal allergies, there might be rare cases of occurrence. Due to its lower gold content, 10K is harder and more durable but has a higher likelihood of causing allergies compared to 18K. If you experience any allergic reactions, please consult a medical professional promptly.

 

[Silver925]
Most of su Jewelry's Silver925 is rhodium-plated. While rhodium coating on the surface essentially prevents rusting, it may develop dullness or tarnish depending on the environment. In such cases, you can either polish it with a silver polishing cloth or clean it by soaking it in a silver-specific cleaning solution. Additionally, for storage, placing it in a sealed bag helps maintain its beautiful condition for an extended period. Silver925 contains over 92.5% pure silver and is less likely to cause metal allergies, although there may be rare instances. If you observe any allergic reactions, please consult a medical professional promptly.

[Makie]
Makie is a traditional Japanese lacquerware technique that involves sprinkling metal powder onto wet lacquer to create intricate designs. Some of su's stones are adorned with a Makie engraving using pure gold powder and lacquer. Due to the nature of Makie, the gold may peel off when rubbed. Please take care not to rub the engraved parts when wearing or cleaning the stone. Avoid prolonged soaking, and after washing with running water, gently wipe away moisture with a soft cloth. Additionally, to maintain the beautiful shine of pure gold, avoid prolonged exposure to sunlight.
