Description

A single round lab-grown diamond glows against warm yellow gold in this pendant necklace, a bright focal point with a polished, classic look. The chain and pendant are solid gold, finished with a high polish that keeps the metal glowing. The stone sits in a four prong setting with an open back, so light reaches it from several directions and gives it lively sparkle. A cable chain carries the pendant and closes with a lobster clasp. You can wear it with a white tee for weekends or a black dress for an evening out. It makes a thoughtful anniversary gift for someone you love.

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.
