This bracelet was born from a real problem. One day, my friend wanted to gift a tennis bracelet to his girlfriend. He visited many jewelry stores and searched online — but everywhere, the same issue came up. All the diamond tennis bracelets had the traditional two-side lock, which is difficult to close securely and can easily break or loosen over time. Plus, it usually takes two people to lock it properly — not very user-friendly.
That’s when my friend came to Vistra Jewels and asked me: “Can you make a custom lab diamond tennis bracelet with a new, stronger, easier lock?”
Our design journey started with countless sketches and prototypes, focusing not only on the perfect round cut lab diamonds, but also on developing a signature lock system — a key USP of this bracelet. Our in-house jewelers and engineers collaborated to craft a proprietary lock mechanism, offering a seamless look with superior safety and durability. Once the lock was perfected, we handcrafted the bracelet using round cut lab-grown diamonds and 14K gold, combining timeless sparkle with everyday functionality.
After seeing the final piece and the amazing feedback, we realized this wasn’t just a custom request — it’s a solution many people need. So we decided to bring this innovation online, so everyone can enjoy a lab diamond tennis bracelet that is both beautiful and practical.
