1.This 18K gold Tanzanite pendant is very beautiful, all set with natural gemstones. The Tanzanite has a very good blueness, making it great for pairing with light or dark clothing. 2. I have tested the Tanzanite bare stone and necklace through ALGT, and the certificate contains detailed data. Please take a closer look and it is also set with natural diamonds. 3. As it is a natural gemstone, there may be slight color differences between the shooting scene and equipment and the actual product. If you mind, please do not participate in the auction. 4. The buyer is responsible for international taxes and fees. If it is a Spanish customer, please do not participate in the auction as customs will require a lot of data and information. 5. The seller bears the international postage and will receive the package within approximately 10-30 days, as I cannot guarantee the customs inspection process and delivery time in each country. 6. If you receive the package and have any questions, please feel free to consult me first, and I will provide detailed answers.
