Lab Grown Diamond Engagement Rings

When you open the box, you do not see a diamond. You see your future: a home with a garden, Sunday morning, and a promise kept. That is what the best engagement rings do. They turn dreams into something you can hold.

Your engagement ring isn't just jewelry. It's the first chapter of a story you're writing together. At Diagaa, we've spent five years helping couples find rings that feel exactly right. Not almost. Not close enough. Exactly right.

Real Diamonds, Real Quality

Every lab diamond engagement ring at Diagaa features VS1+ clarity diamonds with E-F color grading. These aren't alternatives or imitations. They're real diamonds—chemically identical, optically flawless, and just as hard as any diamond pulled from the earth.

Lab-grown diamonds form in controlled environments using the same heat and pressure that create diamonds underground. The result? Stones with better clarity, consistent quality, and pricing that makes sense. You get more diamonds for your investment without sacrificing anything that matters.

Our lab-created diamond engagement rings only have diamonds with Excellent cut grades. This means maximum sparkle, perfect proportions, and maximum light reflection that makes people stop and stare. When your partner shows off their ring, you want that "wow" moment. Our cut quality delivers it.

Say Yes to the One: Claim Your Perfect Ring

Start with the Setting

The diamond setting shapes everything for an engagement ring. It defines how your ring looks, feels, and holds the diamond.

Solitaire engagement rings feature a single center stone with minimal metal. Minimal design that echoes tradition, and breathes a beauty. The diamond takes center stage with nothing to distract from its beauty. Perfect for those who love classic simplicity.

Halo settings surround the center diamond with smaller stones. This makes your center stone look larger and adds more sparkle. Our halo designs pair well with any diamond shape and create a vintage-inspired look.

Bezel settings wrap metal around the diamond for better protection. No sharp prongs to catch on clothing or gloves. Sleek, contemporary, and incredibly secure for active lifestyles.

Three-stone rings use two accent diamonds flanking the center stone. Each stone represents your past, present, and future together. Meaningful symbolism meets stunning design.

Side stone rings feature diamonds running down the band. This engagement ring style looks very unique. It gives more sparkle, more presence, more impact. 

Choose Your Diamond Shape

After the diamond setting, there comes a diamond shape. The diamond shape defines your ring's personality.

Round brilliant cuts offer maximum fire with 58 facets designed to capture light. They're the most popular choice for good reason, with unmatched sparkle and reputation amongst diamond lovers.

Oval diamonds create the illusion of length, making fingers look elegant and elongated. They offer similar brilliance to round cuts with a distinctive modern look.

Emerald cut delivers sophisticated flashes of light through rectangular step-cut facets. Clean, geometric, and perfect for those who appreciate understated elegance.

Cushion cuts combine a vintage look with a modern touch. Their rounded corners and larger facets create a romantic, soft appearance.

Pear shapes combine round and marquise cuts into a unique teardrop shape. Bold, eye-catching, and unlike anything else.

Princess cuts bring a sharp geometric design and extra shine. Modern couples love their contemporary edge.

Marquise and radiant cuts offer distinctive alternatives that maximize carat weight and finger coverage.

Words cannot describe these shapes in a way that visuals can. Discover our complete collection by shape to find the one that speaks to you.

Select Your Metal

14K solid gold offers the best durability for daily wear. With 58.5% pure gold, it resists scratches and bends while maintaining rich color. Most couples choose 14K for this balance between durability and appearance.

18K solid gold contains 75% pure gold for a deeper color and softer feel. It's luxurious, warm, and perfect for those who prioritize gold purity.

10K solid gold provides maximum strength at 41.7% pure gold. Great for active lifestyles and budget-conscious couples.

Choose from yellow gold (classic warmth), white gold (bright modern shine), or rose gold (romantic blush tones). Your metal affects how the diamond looks against the band and your skin.

Love, Evolved: Why Lab-Grown Diamond Rings Shine

Lab-grown engagement rings offer identical quality at a better value. The diamonds are real. The sparkle is real. The hardness, fire, and brilliance—all real.

What's different? The formation process. Instead of mining deep underground, these diamonds grow in labs using advanced technology. This creates:

  • Consistent VS1+ clarity across our collection
  • E-F color grading with no visible tint
  • Excellent cut grades for maximum sparkle
  • Competitive pricing that lets you choose larger stones

Diamonds of 1.00 carat or larger include an IGI certification. Orders over $500 come with third-party jewelry certificates verifying both diamond and gold authenticity. You know exactly what you're getting.

Small Diamonds, Big Impact

Some of our most beloved designs feature engagement rings with small diamonds surrounding the center stone, which we call a pave ring. These accent diamonds add texture, sparkle, and dimension without overwhelming the main stone.

Our pavé bands use tiny diamonds set close together, creating a glittering pathway of light. Channel settings secure small diamonds between metal walls for sleek protection. Hidden halos place small diamonds beneath the center stone for surprise sparkle.

These diamond rings with small diamonds offer sophisticated elegance and work beautifully for everyday wear.

Ring Settings Only Available

Looking to use a family diamond or source your own stone? We offer engagement ring settings only across our collection. Choose your favorite design, select your metal and purity, and we'll craft the perfect setting for your diamond.

This flexibility lets you create exactly the ring you envision while controlling your budget and stone selection.

All you need to do is fill out the custom design form, choose "other" in categories, describe your interest, and click submit. Once received, our team will review and accept your requirements. We care for your vision as if it were our own, ensuring you receive a piece that’s as accurate and beautiful as you envisioned.
