I'm interested in sourcing lab diamond tennis chains for our upcoming product line. We're looking for high-quality options that come in a variety of lengths and styles to cater to different customer preferences. It's important that the diamonds have a brilliant cut and provide the same luxurious look as natural diamonds, while still being eco-friendly. If you have different designs available, please share those too. Additionally, I'd like to know about your pricing, minimum order quantities, and lead times for production. Providing information on your quality control processes would also be helpful. Sustainability and ethical sourcing are key factors for us, so any details you can offer about your production practices would be greatly appreciated. Looking forward to your response!
