I'm reaching out to request a quote for two tennis bracelets crafted from 18k yellow gold featuring lab-grown diamonds. The first bracelet should showcase square princess cut diamonds, each weighing 0.4 carats, and the total length needs to be 18.5 cm. For the second bracelet, I would like it to have round brilliant cut diamonds, each weighing 0.3 carats, also with a total length of 18.5 cm. Please include details on pricing, availability, and production timelines. Additionally, I would appreciate any information regarding the quality of the gold and diamonds, as well as warranty options. Looking forward to your prompt response to help with my decision-making process. Thanks!
