If you mistakenly select the wrong size, you will be responsible for the round-trip shipping costs for exchanges.** **Important Notes for First-Time Silver Jewelry Wearers** ◮ Avoid wearing silver jewelry while visiting hot springs or swimming. The salt in seawater and the acidity of rainwater can mildly corrode metal and cause oxidation. Sulfur in hot springs can turn jewelry black and cause vulcanization. If exposed to these substances, rinse the jewelry with clean water and dry it thoroughly. ◮ Human sweat is slightly acidic (pH 4) as it contains compounds that help kill bacteria. Prolonged contact can corrode metals and accelerate alloy oxidation. As our jewelry is not plated, it is more susceptible to corrosion and breakage when enclosed in sweat. **However, not everyone's sweat will cause breakage. If you have had similar experiences, please exercise extra caution.** To maintain the pristine condition of your silver, it is recommended to wash off sweat after wearing, dry it, and keep it in a dry place. ◮ Products containing chemical additives can also cause silver jewelry to erode. Any product with chemical additives can accelerate the oxidation of jewelry. Common examples include: skincare products, sunscreen, cosmetics, perfumes, essential oils, detergents, and chlorine in swimming pools. If you habitually wear perfume, it is recommended to apply perfume first, then wear your jewelry, to avoid direct contact. ◮ Develop good habits for wearing and storage. Taiwan's climate is humid, with relatively high air moisture. When not wearing your jewelry, be sure to wipe off any sweat or oils with a dry cloth. Store it in a sealed bag to prevent air exposure and maintain dryness. Store each piece separately to avoid friction and scratches. ◮ About Silver Vulcanization 925 sterling silver easily oxidizes and turns yellow or black when exposed to air. This is a natural reaction of silver, similar to how it reacts with hot spring water. A gentle polish with a silver polishing cloth will restore its original luster. However, in hard-to-reach areas like the crevices of a silver chain, it may appear slightly darkened. Vulcanization is a technique where 925 sterling silver is intentionally oxidized to create an antique, rustic, dark patina. This enhances contrast and adds depth, appearing more uniform and aesthetically pleasing than natural air oxidation, and the crevices require no extra cleaning. Regular wear, where the surface of the jewelry rubs against clothing, helps maintain its appearance. ◮ About Us To ensure the highest quality, each of our pieces is crafted through repeated inspections, adjustments, and polishing. We do not permit any porosity or imperfections. To guarantee structural integrity, we employ repeated forging and hammering, giving our silver jewelry a distinct luster and texture. Plated protective films have a high probability of peeling off with prolonged wear, affecting both the environment and the wearer, and obscuring the natural brilliance of silver. Therefore, our pieces are never plated. We dedicate significantly more time to the details. If you have the opportunity to purchase our work, you will notice that its oxidation rate is considerably slower than most other silver products, and its luster is also different. We hope you find a unique piece that belongs to you here.
