If you require a certificate, please send us a private message. We can assist in obtaining one and will create a separate listing for you. Although originating from outer space, meteorites contain elemental compounds formed through geological processes, thus they are generally regarded as minerals. Czech meteorite, discovered in 1787 near the Vltava River in southern Bohemia, was named "MOLDAVITE" in English. It is also known as the "worry-stone" or the Vltavín. Loose stone weight: 3.685g Pendant size including bail approx: 42 x 28 x 9 mm Pendant only weight: 6.794g **Please pay attention to whether the "chain length" and "style" meet your needs. If you misjudge and make an incorrect selection, you will be responsible for the round-trip shipping costs for exchanges.** **Important Information 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 slightly corrode metal and cause oxidation. Sulfur in hot springs will darken the jewelry and cause vulcanization. If exposed to such substances, rinse the jewelry with clean water and dry it. ◮ Human sweat has a relatively high pH of 4 for antibacterial purposes. Studies have shown that prolonged contact can corrode metal 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 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, and keep it dry. ◮ Products containing chemical additives can also cause silver jewelry to corrode. Products 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, it is recommended to spray perfume first and then wear jewelry, avoiding direct contact between the jewelry and perfume. ◮ Develop good habits for use and storage. Taiwan's climate is humid, and the air humidity is relatively high. When not wearing the jewelry, be sure to wipe off sweat and oils with a dry cloth, store it in a ziplock bag to block air and maintain dryness, and store pieces separately to prevent friction and surface scratches. ◮ About Silver Sulfidation 925 sterling silver is prone to yellowing or blackening when exposed to air; this is a natural reaction of silver, 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 silver may appear slightly dark. Sulfidation is a technique where 925 sterling silver is intentionally oxidized to create an antique, aged, dark appearance, enhancing contrast and depth. This is more uniform and aesthetically pleasing than natural air oxidation, and the crevices do not require extra cleaning. Frequent wear, allowing the silver surface to rub against clothing, can help maintain its new appearance. ◮ About Us To present the highest quality, each of our pieces is meticulously crafted through repeated inspection, refinement, and polishing. We absolutely do not allow any porosity or flaws. To ensure the tenacity of the material, we repeatedly forge and hammer the silver, giving our jewelry a unique luster and texture. Plated protective films have a high probability of peeling off with long-term wear, which can affect both the environment and the human body, and it obscures the natural luster of 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 significantly 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.
