We're talking head-turning shine without the mined diamond markup—or the mysterious ethics.

Necklaces that don’t just shine—they speak. Find your signature sparkle with lab-grown diamond magic.

What Makes a Lab-Grown Diamond Necklace So Special?

Lab-grown diamonds are physically, chemically, and visually identical to mined diamonds—they’re real diamonds, just created above ground with modern tech instead of mined from the Earth after millions of years. You get the same brilliant sparkle, with bonus points for sustainability and a more transparent origin story. All the beauty and durability that we love about natural diamonds, with a lighter footprint and a better price tag. (yes, you can absolutely go bigger without the guilt).

When those lab-grown diamonds are crafted into necklaces? That’s where the magic happens. From solitaire pendants and sculptural chokers to full-on tennis necklaces, these pieces deliver serious elegance, ethical sparkle, and endless style. And with a range of gold tones and diamond shapes to choose from, there’s a lab-grown diamond necklace to fit every taste.

Lab-grown, love forever. The future of diamonds is here—and it’s shining around your neck.

Let’s Talk Shapes: Which Diamond Cut Suits You?

One of the most fun parts of picking out your dream diamond necklace? Choosing the diamond shape that fits your vibe. Each shape brings its own energy, from classic and refined to bold and unexpected—so whether you're all about timeless charm or a little offbeat flair, there’s a cut for you.

Round is the forever favorite. Think maximum brilliance, symmetry, and that iconic, twinkly sparkle. If you want something that goes with everything and never goes out of style, round is for you.

Oval diamonds stretch that sparkle just a little longer—literally. The elongated shape gives a flattering, elegant look that feels both modern and graceful. Bonus: it can make your necklace feel a bit larger than its carat weight suggests.

Pear shapes (aka teardrops) are all about unique charm and movement. Whether you wear one solo or in a drop style, they add a little drama without feeling over the top. They’re also surprisingly versatile—delicate or bold depending on your setting.

Emerald cuts are cool, crisp, and super sophisticated. Known for their hall-of-mirrors effect, emerald cuts show off clarity like no other. The long lines feel luxe and architectural—think less sparkle, more shine.

Asscher cuts are like the edgier cousin of the emerald—square instead of rectangular, but with the same clean facets and Art Deco vibes. They’re chic, structured, and unexpected in the best way.

Marquise diamonds are all about vintage glam and big personality. The pointed ends give them a sleek, statement look, and they tend to feel larger on the neck. A little retro, a little regal, and a lot of fun.

Old European cuts are where antique meets romantic. These pre-modern rounds have chunky facets, high crowns, and a softer, candlelit sparkle that feels full of character. If you love vintage jewelry or want something with history baked in, this shape is for you.

Whichever shape you choose, it helps define the mood of your necklace—so think about how you want it to feel: timeless, soft, bold, vintage, modern, a little bit magical. The right cut is the one that feels like you.

Your story. Your style. Your sparkle. Choose the diamond cut and setting that feels most like you.

Settings 101: Prong, Bezel and Beyond

The setting style can totally change the look (and vibe) of your necklace, and who doesn't appreciate a little variety?

• Prong: Lets the diamond breathe and catch light from every angle. Maximum brilliance. Super timeless.

• Bezel: Sleek meets security. The diamond is surrounded in metal, making it great for everyday wear and active life. A vision in gold.

• Half Bezel: The best of both—some shine exposure, some metal-wrapped protection. Low-key chic. Edgy and modern.

Sleek, sculptural, and a little unexpected. A beaded chain meets a bezel-set marquise diamond for a modern twist on everyday shine.

Necklace Styles We’re Loving Right Now

There are diamond necklace designs for every mood and outfit. Here are the styles making us swoon:

• Solitaire Pendant: One stunning stone on a fine chain. Wear it solo or layer it up. It’s the little black dress of necklaces and makes a beautiful gift for any occasion.

• East-West Setting: A twist on tradition—think an emerald or oval diamond flipped horizontally for a fresh silhouette.

• Chunky Gold Solitaire: Big gold energy meets a single bold diamond. Think heirloom, but make it 2025.

• Tennis Necklaces: A full strand of diamonds? Yes, please. These give “I’ve arrived” energy while still playing well with your stack.

• Graduated Tennis Necklaces: A tapered look where the carat weight increases toward the center. Think of it as a little drama in the most wearable way.

• Diamond Choker: If you're looking for a major diamond moment, go bold with a chunky diamond choker.

• Bolo/Lariat Style: A little bit western, a little bit sultry. Long, loose, and dripping in diamonds. Perfect for layering.

Not just for occasions. Lab-grown diamond necklaces are made for everyday magic—brunch, boardroom, or date night.

Metals Matter: Yellow, White, Rose Gold and Platinum

Your metal sets the tone. Our selection includes all the classics:

• Yellow Gold: Warm, vintage-leaning, but trending heavily.

• White Gold: Sleek, cool-toned, and contemporary. Pairs well with colorless diamonds.

• Rose Gold: Romantic and a little unexpected. This pinkish metal suits every skin tone.

• Platinum: Ultra-durable, luxe, and hypoallergenic. Great for statement pieces or tennis necklaces you’ll wear daily.

And yes, karats matter:

• 14k gold is a bit more durable—great for every day.

• 18k gold has a richer, buttery color and a more luxurious feel.

More shine, less compromise. Ethical, stunning, and ready to become your next forever piece.

How to Wear Your Diamond Necklace

• Keep It Classic: A solitaire or tennis necklace paired with diamond studs is a can’t-miss move.

• Stacked & Layered: Mix metal, chain thickness, and lengths for a layered neck moment. Try a chunky choker with a delicate pendant.

• Bold Solo Energy: A full diamond tennis necklace or east-west lab-grown pendant makes enough of a statement on its own—especially paired with a simple tee or blazer.

• Event Dressing: Opt for a graduated style or diamond bolo for those special occasions when you want to turn heads (and sparkle under the lights).

Bold enough to wear solo. Chic enough to stack. Diamond tennis necklaces are the glow-up your jewelry box deserves.

Taking Care of Your Shine

To keep your lab-grown diamond necklace sparkling like day one:

• Clean it regularly with warm water, a drop of dish soap, and a soft brush.

• Store it in a soft pouch or jewelry box to avoid scratching.

• Remove before working out, sleeping, or showering (it’s durable, but not invincible).

• For tennis styles, double-check clasps to protect your purchase and your sparkle.

A little edge, a lot of elegance. A beaded chain and bezel-set pear diamond come together for the perfect mix of cool and classic.
