Description
Interlocking two-tone circles hold a round lab-grown diamond at the center of this polished circle necklace in 14K gold, with smaller lab-grown diamonds set around it. The metal is solid gold with a rhodium finish, so a bright silver-tone shine plays against the warmer tone across the surface. The pendant hangs from a fine cable chain at the center, and a lobster clasp closes at the back so it stays fastened as you move. Wear it over a crew neck sweater or alone with an open collar shirt. A thoughtful pick for someone marking a birthday.

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.
