Description
Round lab-grown diamonds form an unbroken line of sparkle in this yellow gold tennis necklace, bright against the warm metal. The strand is solid gold with a polished finish that lets every stone catch the light. Each stone sits in a straight, even row, so the necklace lies smoothly and reads as one continuous band of brilliance. A box catch closes it, backed by a safety clasp for extra hold. You can wear it alone with a crisp white shirt or layer it under a dressier neckline for evening. A lovely choice for someone marking an April birthday or 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.
