A tennis necklace takes the same continuous-line idea as a tennis bracelet and carries it around the neckline: a flexible row of diamonds designed to follow the curve of the neck rather than sit stiff.

The collection ranges from classic single-row styles to graduated designs, where the diamonds grow larger toward the center. Choose round brilliant, oval, emerald-cut or heart-shaped diamonds, or a graduated oval-and-pear design. Settings include traditional prong-set styles and bezel-set Riviera designs. Each piece is made in 14K white, yellow or rose gold, depending on the design.

Every necklace is set with lab grown diamonds, F color or better with VS clarity or better. That is a big reason these higher total carat weights are available at these prices — matching twenty or thirty carats of natural diamonds into a single line would put the cost in a very different range.

Lengths vary by design, from 16 to 22.6 inches, and some styles offer more than one length. Check each product page for the exact length, clasp, carat weight and price.

If you want to understand the difference between the two diamond origins, our guide to lab grown vs. natural diamonds explains how they compare in appearance and price.
