I'm reaching out for a quote on laser engraving services for jewellery pieces made of gold, silver, and brass. Specifically, I'm interested in small-sized items that require intricate designs. Please provide details on your capabilities for engraving these materials, including any specialized techniques or finishes you offer. Additionally, I'd like to know the turnaround time for orders, the minimum order quantity, and pricing options based on different volumes. If you have any examples of your previous work in similar materials, sharing those would be greatly appreciated. Looking forward to your timely response so we can explore potential collaboration. Thank you!
