Description
Bright white round lab-grown diamonds run in a graduated line along this yellow gold tennis necklace, a sparkle that reads bold yet polished. The necklace is solid yellow gold with a polished finish that gives each setting a warm, smooth glow behind the stones. The diamonds are faceted and step up in size toward the center, so the line catches light as you move and lies close against the skin. A box catch clasp with a safety clasp keeps it closed. Wear it with an open-collar white shirt or a black evening dress. A fitting gift for an anniversary.

What affects the price of diamond necklaces?
Metal, diamond weight and diamond type drive the price. Solid 14K gold costs more than sterling silver or gold-plated silver, and a higher total carat weight raises it further. Lab-grown and natural diamonds are priced differently too. Use the Price filter on this page to set a budget.
Which diamond necklace styles are most popular?
Infinity, teardrop and circle styles lead the list. Diamond hearts, lockets and two-stone necklaces in 14K gold follow closely, with bar slide and solitaire designs also well represented. Most are on an 18 inch chain, so they sit near the collarbone.
Should I choose a lab-grown or natural diamond necklace?
Both are real diamonds with the same sparkle. Lab-grown stones are made in a lab, and many of the larger necklaces here use them, which allows a bigger total carat weight. Each product title says whether the diamonds are lab-grown, so check it as you browse.
Which diamond necklace is best for everyday wear?
A solitaire, small teardrop or bar slide suits daily wear. Their simple shapes sit close to the neck and are easy to layer under collars. Choose 14K gold for the most durable everyday option, since plated pieces can wear over time.
Is white gold or yellow gold better for a diamond necklace?
Choose white gold for a cool look, yellow for warmth. White gold makes the diamonds look bright and icy, while yellow gold gives a richer glow. Some teardrops also come in two-tone gold. Pick the color that matches the jewelry the wearer already owns.
How do I care for a diamond necklace?
Clean it gently and store it separately. Wipe with a soft cloth or use mild soapy water and a soft brush, then dry well. Keep it in a pouch so the chain does not tangle. See our jewelry care tips for more.
