德国采购需求：定制珠宝，14k金项链，最佳鼻环，定制吊坠，银戒指，环形耳环

I'm looking to place an order for a custom 925 sterling silver ring with rhodium plating—no gold, please. The ring should have a width of around 5-7 mm and showcase high-quality cubic zirconia stones, sized to fit US 6 (16.5 mm). Could you share the pricing for a single piece, your minimum order quantity, and the estimated production and shipping timeline? I'm located in Germany and would appreciate your quick response. Thanks!
