Size Information- Gemstone Size: Approx. 12x17mm / 12.5 carats Ring Size: Adjustable/Resizable Band Material Information- Natural London Blue Topaz, crafted with 925 sterling silver. The black detailing is achieved through a special sulphidation treatment. Q: What is the common "sulphidation treatment" for Nepalese jewelry? A: When silver jewelry appears blackened, "oxidation" is a common layman's term. Oxidation refers to a substance reacting with oxygen. However, silver (jewelry) turns black due to a reaction with "sulfur" in the air, forming "silver sulfide." The black material on the surface of silver (jewelry) (which can be coffee-colored, light brown, dark brown, or reddish-brown) is indeed silver sulfide. If silver (jewelry) is not well-maintained, it will naturally darken and lose its luster. Therefore, the correct term is "sulphidation," resulting from reactions with hydrogen sulfide or sulfur dioxide in moisture present in the air, thus forming silver sulfide on the surface. In Nepalese silver craftsmanship, specific "sulphidation" treatments are intentionally applied (giving a dark or aged appearance) to enhance the unique character of the handicraft. If you prefer not to have this finish, you can try gently brushing the treated area multiple times with a soft brush dipped in toothpaste to remove the deliberate sulphidation. Package Includes- Ring, jewelry box, silver polishing cloth, PVC jewelry storage pouch ❤️Special Note: Nellie was established in 2017. While there is no physical storefront in Taiwan, Nellie has a physical store in Nepal. We welcome inquiries for a wide range of high-end jewelry (925 sterling silver, K gold, pure gold) and gemstones, with the option for in-person selection. All items displayed are covered by after-sales service, and international certificates can be provided. We also support various authentication methods. 💫A Special Note from Nellie: For jewelry designed with natural stones, we strive to handle the gemstones with utmost care to avoid damage. However, as each piece is entirely handcrafted, there's a possibility of minor, unintentional marks on the gemstone during the setting process. Some may be visible to the naked eye, while others might be imperceptible. Please confirm your acceptance of this potential "flawed beauty" before making a purchase. (Most natural stones inherently possess crystal structures or internal fractures; we encourage you to inquire or research this information before purchasing. 😊) ■Shipping Information All Nellie products are shipped from Nepal.
