Three Stone Engagement Rings

Three stone engagement rings combine striking beauty with meaningful design, featuring a center stone paired with two side stones that create extra brilliance and balance. At Carat Diamonds, our collection includes handcrafted rings with lab grown diamonds and moissanite in popular shapes like oval, pear, emerald, round, and cushion cuts. Each design offers exceptional sparkle while giving you a luxurious look at a more accessible price.

A Ring That Means Something

Most rings are beautiful. But a three stone ring carries a story.

Each stone represents a chapter of your relationship:

The first stone: stands for everything that brought you here the late nights, the laughter, the moments that made you fall in love.
The center stone: represents right now the commitment you make today and the love you choose every single morning.
The third stone: looks forward to the life you will build, the family you will grow, and every adventure waiting ahead.

You do not just wear this ring. You wear your whole love story on your finger set in lab grown diamonds or moissanite that shine as brightly as the moment itself.

Every Detail, Done Right

A beautiful lab grown diamond or moissanite deserves a setting that does it justice. Here is how we build every ring in this collection:

Stones matched by hand: A three stone ring looks its best when all three stones share the same brightness and color. Our team selects every set of three stones by hand to make sure they match. No dull side stones. No mismatched tones. Just three stones that work together as one.
Certified metals only: We build every band in Platinum, Carat White Gold, Carat Yellow Gold, or Carat Rose Gold. Each piece passes official purity testing before it reaches you. You wear verified quality on your finger, not guesswork.
Settings made to last: Your stones stay firmly held in precision-crafted claws that grip without hiding the light. Whether you choose a clean four-prong setting or a more secure six-prong design, every setting gets built to the same high standard.
Fully conflict-free: Every stone comes with a documented, traceable origin. No mining. No ethical uncertainty. You wear your ring knowing it caused no harm to get to you.

Find Your Style

No two women are the same and neither are our rings. Whether you choose a lab-grown diamond or moissanite, you pick the stone shape combination that speaks to you. Here are some of our most loved looks:

Three Round Brilliants: Three round stones side by side create a ring that glows from every angle. Classic, balanced, and endlessly wearable. The kind of ring that looks just as beautiful on a Tuesday morning as it does at a black-tie dinner.
Oval Center with Pear Sides: An oval centre stone with two pear-shaped side stones creates a long, graceful silhouette on the hand. It feels romantic and modern at the same time and it photographs beautifully.
Emerald Cut with Baguettes: If you love clean lines and quiet elegance, this is your ring. An emerald cut center with baguette side stones delivers a composed, architectural look that never tries too hard.
Cushion Cut with Trillions: A soft cushion cut centre with trillion side stones creates a ring full of warmth, color, and depth. It is bold without being loud and it suits women who want their ring to feel as personal as it looks.

Design Your Own Three Stone Ring

Choose Your Stone: Pick lab grown diamond for crisp white brilliance or moissanite for vivid, fiery sparkle both ethically grown, both built to last.
Pick Your Shape: Select your center stone shape and side stone combination round, oval, cushion, emerald, pear, or trillion. The choice is yours.
Select Your Metal: Choose from Platinum, White Gold, Yellow Gold, or Rose Gold to complete the look that feels right for you.
Build It Your Way: Every combination we offer comes with the same certified metals, hand-matched stones, and expert craftsmanship no extra cost, no compromise.

More Ring for Your Money

Here is something worth knowing: lab grown diamonds and moissanite cost significantly less than mined stones of the same quality. That price difference does not mean lower quality. It means you skip the mining premium and put that money back into your ring.

Higher clarity grades: VS1 and VVS stones the ones that look completely flawless to the eye sit within reach when you choose lab grown.
Better color grades: Colorless stones in the D, E, and F range become realistic choices without pushing your budget past its limit.
More to invest in the setting: With the savings from lab grown stones, you can choose a more detailed setting, a premium metal, or simply feel good knowing you did not overpay.

You deserve a ring that excites you. Lab grown diamonds and moissanite make that possible.

A Ring You Feel Good About

More women today want to know where their ring comes from. They want beauty and they want it without a cost to the planet or to other people.

Our lab grown diamonds and moissanite grow in specialist laboratories using processes that replicate how diamonds form in nature without any mining. Every stone grows in a fully transparent production process.

When you wear a ring from our collection, you wear something that reflects who you are a woman who cares about quality, about ethics, and about the story behind the things she loves.

Your Ring Is Waiting

The right ring does not just look good. It feels right the moment you put it on. A lab grown diamond brings crisp, white brilliance. Moissanite brings vivid, fiery sparkle. Both fit your values and the love behind the ring.

Our Three Stone Engagement Rings collection brings together hand-matched lab grown diamonds and moissanite, certified metals, and craftsmanship built to last decades of daily wear.
