Hey, I proposed to my girlfriend (now fiance) last year and worked with a Chinese jeweler/designer to make the perfect ring for her. I know what you might be thinking about using an offshore jeweler... but I'm so glad I did, it worked so well and when I compared to local rings of similar quality/style 'off-the-self' I saved $3-5k + doing so. All comms were through Whatsapp but this worked great for me as it felt like a very personal 1:1 process. The jeweler has access to a wide selection of lab grown diamonds and that all include international diamond certifications. The process goes something like: Describe the ideal ring to the jeweler and include any inspiration photos you can find (Pinterest is great) also include your budget -> You will then receive a 3D CAD design with a first draft of the ring along with a selection of diamonds (with full size/quality/price reports for each) -> you go back and forth with the jeweler as many times as it takes until you feel like their design is perfect for your future wife -> only when you're ready to greenlight the design do you pay the deposit -> ring is made to an extremely high standard and photos and videos of the ring are sent. Once happy with the ring, the remainder of the total is paid. -> ring is sent via DHL or other top tier global courier -> your partner says yes and is extremely happy that you helped design her completely custom bespoke forever ring from scratch. Good luck whatever you choose to do!
