Description
Round lab-grown diamonds run in an unbroken line of bright white sparkle in this tennis necklace, set in polished white gold. The solid gold chain is finished with rhodium plating, which gives it a crisp silver-tone shine that keeps the stones looking clear and icy. Every link holds a round stone, so the necklace lies flat and drapes with an easy, fluid weight. A box catch clasp with a safety latch closes it securely. You can wear it with a crisp white shirt for the office or a black dress for dinner out. A fitting gift for someone with an April birthday.

Should I choose round or emerald-cut stones in a tennis necklace?
Round stones sparkle more, while emerald-cut stones look sleeker. Round diamonds give a classic, lively shimmer from every angle. Emerald-cut stones have long, flat facets that read as a clean, architectural line. Pick round for a traditional look and emerald-cut for something more modern.
What length of tennis necklace should I pick?
Pick 16 to 18 inches for a close fit at the collarbone. Longer lengths like 20 to 26 inches drop lower and layer more easily. The bolo styles slide to adjust, so they suit anyone between sizes. Measure a necklace you already wear to find your favorite length.
What affects the price of tennis necklaces?
Total carat weight and metal are the biggest drivers. Stone cut, color and clarity grades, stone size, and necklace length also matter, as does 14K white versus yellow gold. Use the Price filter on this page to set a budget, then compare options within it.
Which tennis necklace styles are most popular?
Round lab-grown diamond styles in 14K white and yellow gold lead. Classic 20 inch lines and bolo necklaces appear near the top, followed by emerald-cut styles in both metals. Many round styles come in 18 inches. See our diamond necklaces for more.
