A diamond necklace is one of the most versatile pieces in any jewelry collection — equally at home with everyday outfits and special occasions. Lab grown diamonds make that timeless sparkle both more affordable and more ethical, letting you wear a real, certified diamond with a clear conscience. Here is how to choose a lab grown diamond necklace you will reach for again and again.
Lab grown diamond necklaces offer identical brilliance to mined-diamond pieces at 60–85% less cost, and without the ethical concerns of mining. Solitaire pendants are the most versatile everyday choice, while tennis and station necklaces make a bolder statement. Look for independent GIA or IGI certification and a well-cut stone for maximum sparkle.
Why choose a lab grown diamond necklace
Lab grown diamonds are real diamonds with the same hardness, fire, and brilliance as mined stones — the only differences are origin and price. Because they are created in a controlled facility rather than mined, they carry a smaller environmental footprint and none of the ethical questions associated with mining. For the full picture, read our guide to whether lab grown diamonds are an ethical alternative to mined diamonds. The lower price also means you can choose a larger or higher-quality stone than a mined budget would allow.
The most popular necklace styles
Solitaire pendant
A single diamond on a fine chain is the ultimate everyday piece — understated, elegant, and endlessly wearable. It layers well and suits any neckline, which is why it is the most popular choice. Browse designs in our pendants and necklaces collection.
Tennis necklace
A continuous line of matched diamonds around the neck makes a genuine statement. Lab grown diamonds bring this once-extravagant style within reach, since it uses many stones and the savings add up quickly.
Station necklace
Diamonds spaced at intervals along a chain give a modern, understated sparkle that catches the light as you move — a great choice for everyday luxury that is not too formal.
Halo pendant
A center diamond framed by smaller stones looks larger and adds extra brilliance, delivering maximum presence for the budget.
How to choose the right necklace
Prioritize cut, which controls how much a diamond sparkles, then choose a color grade of G–H and clarity of VS for a stone that looks flawless to the eye at excellent value. Consider chain length: 16–18 inches sits at or just below the collarbone and suits most necklines, while longer chains work well for layering. Our diamond education hub explains the grades in detail, and our lab grown diamond guide covers how the stones are grown and certified.
Styling your necklace
A solitaire pendant pairs effortlessly with matching studs from our diamond earrings range for a coordinated look, or layer necklaces of different lengths for a contemporary feel. White metals keep the focus on the diamond's brilliance, while yellow or rose gold add warmth.
Caring for your necklace
Lab grown diamonds are just as hard as mined diamonds and stand up to daily wear. Clean gently with warm water and mild soap, store the necklace separately to protect the chain and setting, and have the setting checked periodically to keep the stone secure.

Are lab grown diamond necklaces real diamonds?
