Natural Gemstone / Sugilite / Untitled / Sterling Silver Jewelry

Sugilite is a gemstone variety primarily characterized by its purple hues. In Taiwan, it is commonly referred to as "Shu Ju Lai," while the Chinese National Standard officially names it "Su Ji Shi." Both "Shu Ju Lai" and "Su Ji Shi" are phonetic transliterations of the English name Sugilite, which originates from its discoverer, Kenichi Sugi. Consequently, it is also known as Sugi Stone in Japan. *Includes certificate from NTU Gemological Institute Dimensions including bail: 51 x 28 x 15 mm **Please ensure the "chain length" and "style" meet your needs. If you mistakenly choose incorrectly, you will be responsible for the round-trip shipping costs for exchanges.** **Important Notes for First-Time Silver Jewelry Wearers** ◮ Avoid activities like visiting hot springs or swimming while wearing silver jewelry. The salt in seawater and the acidity of rainwater in nature can mildly corrode metal and cause oxidation. Sulfur in hot springs can also cause jewelry to turn black and undergo sulfidation. If exposed to such substances, it is recommended to rinse the silver jewelry with clean water and dry it thoroughly. ◮ Human sweat has a higher pH of 4 for its antibacterial properties. 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 maintain the newness of your silver jewelry, it is recommended to wash and dry it after wearing it for the day if it comes into contact with sweat, and keep it dry. ◮ Products containing chemical additives can also cause silver jewelry to erode. Products with chemical additives can indeed accelerate the oxidation of jewelry. Common examples include: skincare products, sunscreen, cosmetics, perfumes, essential oils, cleaning agents, chlorine in swimming pools, etc. If you habitually wear perfume, it is recommended to apply perfume first, then wear your jewelry, and avoid direct contact between the jewelry and 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. Store it in a ziplock bag to block air and maintain dryness. Also, store each piece separately to prevent friction and surface scratches or damage. ◮ Regarding the sulfidation of silver jewelry 925 sterling silver can easily 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. Simply polishing it gently with a silver polishing cloth can restore its original luster. However, in hard-to-reach areas like the crevices of a silver chain, it may appear slightly darker. The sulfidation technique involves directly oxidizing 925 sterling silver jewelry to create a rustic, aged, dark appearance, enhancing contrast and adding depth. This is more uniform and aesthetically pleasing than natural air oxidation, and the crevices do not require extra 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 pieces is crafted through repeated inspections, revisions, and polishing. We absolutely do not allow any pinholes or imperfections. To ensure the resilience of the material, we repeatedly forge and hammer it, giving our silver jewelry a unique 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, and it also obscures the natural luster of silver. Therefore, our works have never been 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 considerably slower compared to most other silver products, and its luster is also different. We hope you can find a unique piece of jewelry that belongs to you here.
