I ordered this exact bracelet for my sister at https://luxurydiamonds.ca/collections/lab-created-diamond-tennis-bracelet https://luxurydiamonds.ca/collections/lab- created-diamond-tennis-bracelets. At first, I was worried about the clasp, too, but it has a double, secure lock with a safety catch—it definitely won’t come undone by accident. The links are beautifully crafted; the bracelet sits comfortably on the wrist and doesn’t snag on clothing. My sister wears it all the time and is incredibly happy with it. Shipping was fast, and the service was top-notch!
