I'm currently looking to source some gold jewelry and would like to explore your offerings. Specifically, I'm interested in various styles, including rings, necklaces, and bracelets. Quality and craftsmanship are key factors for us, so please provide details on your products, including any certifications or hallmarking you offer. Additionally, could you share your pricing structure, lead times, and any minimum order quantities? If you have a catalog or images of your designs, that would be great! Looking forward to your prompt response as we aim to establish a fruitful partnership.
