Description
Sparkling round lab-grown diamonds run in an unbroken line along this white gold tennis necklace, a bright row that looks polished from every angle. The solid white gold carries a rhodium plating that gives it a crisp silver-tone shine, and the polished finish keeps the surface smooth. Each stone is set close to the next so the chain drapes with an easy, fluid weight and lies flat. A box catch with a safety clasp closes at the back. You can wear it with a white shirt and jeans or with a black dress for dinner. A thoughtful choice for an anniversary.

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.
