I'm looking for high-quality gold products for our upcoming project. Specifically, I'm interested in various forms, such as raw gold, gold sheets, and other gold-related items. Could you provide detailed information on your available options, including specifications, pricing, and minimum order quantities? Additionally, I'd appreciate insights into your production lead times and any certifications or quality standards that your gold products meet. This info will be crucial for our decision-making process. Thank you!
