Buying guide
A round tennis necklace with stones of one size gives an even, unbroken line of sparkle that looks the same from every angle. Most designs here are graduated: the round lab-grown diamonds are largest at the center front and get smaller toward the back, which draws the eye forward and sits well at the collarbone. Some designs pair the stones with a polished bead back or flexible links for comfort.
Prong settings hold each round-cut stone with small metal claws, letting in the most light for the brightest sparkle. A bezel set tennis necklace wraps each stone in a thin rim of metal, which looks smooth and modern and protects the edges of the stones.
Carat weight is the total weight of all the lab-grown diamonds in the necklace. Every design offers 10, 15 or 20 carats total weight, and some also start at 5, 7 or 9 carats. Rose gold comes in 10K, 14K or 18K and gives the stones a warm frame; silver keeps them bright and is the more affordable choice. Necklaces start under $1,800, and most are between about $4,300 and $4,550 at their smallest option.
