美国采购需求：戒指首饰、时尚耳环、吊坠首饰、项链首饰、时尚手链、银质结婚戒指

I'm currently in China and looking to produce 8 custom rings. I need 8 unique designs, ideally with 1-2 pieces each for sampling. The material can be either 925 silver or stainless steel, so I'd appreciate your insight on which option might be better. It's important that the rings have a heavy, solid feel, not hollow, and I'd like them to include laser engraving for text or codes, done either on the inner or outer surface. In terms of finish, I'm considering both matte and polished. For this project, I'm also looking for high-quality craftsmanship and a fast turnaround for samples—preferably within 7-10 days. If possible, I'd like to visit the factory in person or see samples as soon as I can. Please let me know the MOQ for engraved rings, sample costs, and your factory address. I can share reference images with you right away!
