If you make an incorrect judgment, you will be responsible for the round-trip shipping costs for any exchanges.** **Important Notes for First-Time Silver Jewelry Wearers** ◮ Avoid wearing silver jewelry while bathing in hot springs or swimming. The salt in seawater and the acidity of rainwater can subtly corrode metal and cause oxidation. Sulfur in hot springs will cause jewelry to darken and undergo sulfidation. If exposed to these substances, it is recommended to rinse the silver jewelry with clean water and then dry it thoroughly. ◮ Human sweat has a slightly acidic pH of 4 for skin sterilization. Studies have shown that prolonged contact can corrode metals and accelerate alloy oxidation. Our jewelry is not plated with other materials on the surface, making it more susceptible to corrosion and breakage when encased in sweat. However, **not everyone's sweat will cause breakage. If you have had similar experiences, please be extra cautious.** To keep silver jewelry looking new, it is recommended to wash and dry it after wearing it for the day if it comes into contact with sweat, and to keep it dry. ◮ Products containing chemical additives can also cause silver jewelry to corrode. Any product with chemical additives can actually accelerate the oxidation of jewelry. Common examples include: skincare products, sunscreen, cosmetics, perfumes, essential oils, detergents, chlorine in swimming pools, etc. If you habitually wear perfume, it is recommended to spray perfume first, then wear the jewelry, avoiding direct contact between the jewelry and the perfume. ◮ Develop good habits for use and storage. Taiwan's climate is humid with relatively high air moisture. When not wearing the jewelry, be sure to wipe off any sweat or oils with a dry cloth, and store it in a ziplock bag to block air and maintain dryness. Store pieces separately to prevent them from rubbing against each other and causing surface scratches or damage. ◮ About Silver Sulfidation 925 sterling silver easily oxidizes and turns yellow or black when exposed to air; this is a natural reaction of silver, similar to how pure silver reacts with hot spring water. A gentle wipe with a polishing cloth can restore its original luster. However, in hard-to-reach areas like the crevices of a silver chain, the jewelry may appear slightly darker. The sulfidation technique involves intentionally oxidizing 925 sterling silver jewelry to create an antique, aged, dark appearance, enhancing contrast and adding depth. This is more uniform and aesthetically pleasing than natural air oxidation, and the crevices require no additional cleaning. Frequent wear, where the surface of the jewelry rubs against clothing, can help maintain its newness. ◮ About Us To present the highest quality, each of our works undergoes repeated inspection, revision, and polishing, allowing for absolutely no pores or imperfections. To ensure the strength and resilience of the material, we repeatedly forge and hammer the silver, giving our jewelry a distinctive luster and texture. Protective plating has a high probability of peeling off with prolonged wear and can affect both the environment and the body, obscuring the natural luster of silver. Therefore, our works are never plated. We invest significantly more time in the details. If you happen to purchase one of our pieces, you will notice that its oxidation rate is significantly slower compared to most other silver products, and its luster is also distinct. We hope you can find a piece of jewelry that is uniquely yours here.
