If you misjudge and require an exchange for a different length, you will be responsible for the round-trip shipping costs.** **Important Notes for Wearing Silver Jewelry for the First Time** ◮ Avoid wearing silver jewelry while visiting hot springs or swimming. The salt in seawater and the acidity of rainwater can slightly corrode metals and cause oxidation. Sulfur in hot springs will cause jewelry to darken and undergo vulcanization. If exposed to these substances, rinse the silver jewelry with clean water and dry it thoroughly. ◮ Human sweat has a slightly acidic pH of 4 for antibacterial purposes. 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 enclosed by sweat. However, **not everyone's sweat will cause breakage. If you have had similar experiences, please be extra cautious.** To keep your silver jewelry looking new, we recommend cleaning and drying it after wearing it for the day, and storing it in a dry place. ◮ Products containing chemical additives can also cause silver jewelry to corrode. Any product with chemical additives can 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, we recommend applying perfume first, then putting on your jewelry, to avoid direct contact between the jewelry and the perfume. ◮ Develop good habits for wearing and storing your jewelry. Taiwan's climate is humid, and the air's moisture content is relatively high. When not wearing your jewelry, be sure to wipe off any sweat or oils with a dry cloth, and store it in a ziplock bag to prevent air exposure and maintain dryness. Store pieces separately to avoid friction and surface scratches. ◮ About the vulcanization of silver jewelry 925 sterling silver can oxidize and turn yellow or black when exposed to air; this is a natural reaction of silver jewelry, similar to how pure silver reacts with hot spring water. Gently polishing with a silver polishing cloth will restore its original luster. However, in hard-to-reach areas like the crevices of a silver chain, the jewelry may appear slightly darker. Vulcanization is a technique that directly oxidizes 925 sterling silver jewelry to create an antique, distressed, dark appearance, enhancing contrast and adding depth. This is more even and aesthetically pleasing than natural air oxidation, and the crevices do not require extra cleaning. Regular wear, where the surface of the jewelry rubs against clothing, helps maintain its shine. ◮ About Us To present the highest quality, each of our pieces is meticulously crafted through repeated inspections, adjustments, and polishing. We do not permit any porosity or flaws. To ensure structural integrity, we repeatedly forge and hammer the metal, giving our silver jewelry a distinct luster and texture. Plated protective films have a high probability of peeling off with prolonged wear, which can affect both the environment and the human body, while also obscuring the natural luster of the silver. Therefore, our pieces are never plated. We invest significantly more time in the details. If you have the opportunity to purchase one of our pieces, you will notice that its oxidation rate is considerably slower compared to most other silver products, and its luster is also different. We hope you find a unique piece of jewelry that belongs to you here.
