GIA & IGI Certified Lab Grown Loose Diamonds for Sale at 25% Off

Every diamond shape tells a different story. Some are designed to maximise brilliance, while others are chosen because they flatter the hand, suit a particular jewelry style, or make the most of your budget. Before you focus on carat weight alone, take a look at how each shape performs in real life and where it shines the most.

Our collection includes loose diamonds GIA certified as well as IGI certified diamonds, making it easy to compare different options while shopping with confidence.

1. Round Brilliant Cut Diamond

When You Simply Want Maximum Sparkle

If your top priority is getting the brightest looking diamond, a round brilliant is hard to beat. Its carefully designed 58-facet pattern has been refined over many years to reflect as much light as possible, which is why it's often used as the standard for comparing other diamond shapes.

Another reason buyers keep coming back to round diamonds is their versatility. Whether you prefer a simple solitaire, a halo, or a bezel setting, this shape fits almost every design. If you're buying your first loose diamond and aren't sure where to start, a round brilliant is always a safe choice.

Best suited for: Engagement rings, diamond studs, solitaire pendants, tennis bracelets, and almost any custom jewelry design.

Perfect for: Buyers who want maximum sparkle and a diamond shape that works beautifully across almost every jewelry style. 

2. Oval Cut Diamond

Want a Bigger Look Without Paying for More Carats?

If your goal is to make every carat count, an oval diamond is one of the smartest choices you can make. Its elongated shape naturally creates the illusion of a larger diamond, helping you achieve an impressive look without moving up to a higher price point.

One thing many first time buyers don't realise is that not every oval has the same proportions. A slightly longer oval creates a more elongated appearance, while a wider oval looks softer and fuller. Choosing the right length to width ratio can completely change the personality of the finished ring.

Best suited for: Engagement rings, solitaire pendants, diamond studs, tennis bracelets, and custom jewelry designs where a larger-looking center stone is the focus.

Perfect for: Buyers who want a diamond that appears larger than its carat weight while maintaining a graceful, elongated look. 

3. Emerald Cut Diamond

The Diamond That Doesn't Hide Anything

If you're someone who likes clean lines and a diamond with a calm, refined appearance, an emerald cut is worth considering. Instead of creating lots of tiny flashes of light, its long step facets produce larger reflections, often called the "hall of mirrors" effect.

Because the facets are more open, this shape reveals the diamond's clarity more easily than most brilliant cuts. That's why it's worth choosing a higher clarity grade if your budget allows. The result is a diamond that stands out through its clean appearance rather than flashy brilliance.

Best suited for: Engagement rings, solitaire pendants, tennis bracelets, statement earrings, and custom jewelry that highlights the diamond's clean, geometric shape.

Perfect for: Buyers who value clarity, classy appeal, and a sophisticated look over maximum sparkle. 

Buying Tip: Look for a length to width ratio around 1.35 to 1.50 if you prefer a beautifully elongated appearance.

4. Cushion Cut Diamond

Soft Corners That Never Feel Off the Trend

A cushion diamond may look simple at first, but no two cushions look exactly alike. Some are cut to create bold flashes of light, while others have extra facets that produce smaller, more frequent sparkle.

That's why it's worth comparing a few cushion cut diamonds before making your decision. Two stones with the same shape can have completely different personalities, allowing you to choose the look that matches your style instead of settling for the first one you see.

Best suited for: Engagement rings, halo pendants, diamond studs, vintage-inspired bracelets, and custom jewelry with a soft, romantic feel.

Perfect for: Buyers who love rounded shapes, balanced sparkle, and a diamond with a classic look that never goes out of style. 

5. Radiant Cut Diamond 

For Buyers Who Can't Decide Between Round and Emerald

Radiant diamonds are a great choice if you like lots of brilliance but want something a little different from the traditional round shape. They combine a rectangular or square outline with a brilliant cut facet pattern, giving you the best of both worlds.

Their trimmed corners are another advantage. They're better protected than pointed shapes like princess or marquise, making radiant diamonds a practical option for people who wear their jewelry every day.

Best suited for: Engagement rings, solitaire pendants, tennis bracelets, statement earrings, and custom jewelry that showcases exceptional brilliance.

Perfect for: Buyers who want the sparkle of a round diamond with the distinctive shape and clean lines of an emerald cut. 

6. Princess Cut Diamond

Sharp Geometry with Modern Character

If round and oval diamonds feel too soft for your taste, a princess cut offers a completely different style. Its square shape and clean corners create a bold, structured appearance that stands out in a simple setting.

Because the corners are pointed, they should always be protected with sturdy prongs. A well-made setting not only keeps the diamond secure but also helps it stay beautiful for years of everyday wear.

Best suited for: Engagement rings, geometric pendants, stud earrings, modern bracelets, and custom jewelry with clean, contemporary styling.

Perfect for: Buyers who prefer bold, angular designs and a diamond with a modern, structured appearance. 

7. Pear Cut Diamond

Every Diamond Has a Direction

Pear diamonds are popular because they offer two looks in one. Wear the pointed end towards your fingertip for a longer finger appearance, or reverse it for a more modern style.

That flexibility makes pear diamonds a favorite for buyers who want something unique while still choosing a shape that's easy to wear every day. If you're exploring diamonds for sale online, this shape is an excellent choice for its distinctive versatility and classy appeal.

Best suited for: Engagement rings, solitaire pendants, drop earrings, Toi et Moi rings, and other custom jewelry that highlights its distinctive teardrop shape.

Perfect for: Buyers who want a unique diamond that offers versatility, graceful proportions, and a look that stands out from traditional shapes. 

8. Marquise Cut Diamond

One of the Biggest Looking Diamonds for Its Weight

If your goal is to make every carat count, marquise diamonds deserve a closer look. Its long shape spreads the weight across a larger surface, making it appear bigger than many other diamond shapes with the same carat weight.

It's a great choice for buyers who want a noticeable center stone without stretching their budget to the next carat size.

Best suited for: Solitaire engagement rings, east-west pendants, drop earrings, vintage inspired bracelets, and custom jewelry that highlights its elongated silhouette.

Perfect for: Buyers who want one of the largest looking diamond shapes for its carat weight while achieving a bold, eye-catching appearance. 

Buying Tip: A well cut marquise should have balanced curves on both sides and minimal bow-tie effect across the center.

9. Asscher Cut Diamond 

Small Details Make a Big Difference

Asscher cut is often chosen by buyers who like clean patterns and fine details. While it looks similar to an emerald cut at first glance, its square shape creates a completely different visual effect. As light moves through the step facets, you'll notice a beautiful pattern that seems to draw your eye towards the center.

Because every side of the diamond is easy to see, symmetry becomes very important. A well-cut asscher should have even corners, straight facet lines, and a balanced pattern throughout the stone.

Best suited for: Engagement rings, solitaire pendants, vintage-inspired earrings, Art Deco jewelry, and custom designs that showcase its distinctive step-cut pattern.

Perfect for: Buyers who appreciate precise craftsmanship, geometric beauty, and a diamond with a refined, vintage-inspired character. 

10. Heart Shape Diamond

A Diamond That's Chosen for Meaning, Not Trends

A heart shaped diamond is more than just a beautiful cut. It's often chosen to celebrate life's biggest moments, whether that's an engagement, an anniversary, or a gift for someone special.

Although it looks simple, cutting a heart diamond takes great skill. Both sides need to match perfectly; the center cleft should be well defined, and the point must be protected once it's set. If you want the heart shape to stand out clearly, many jewelers recommend choosing a stone of at least one carat, as the outline becomes easier to recognize.

Best suited for: Engagement rings, meaningful pendants, anniversary gifts, earrings, and custom jewelry designed to celebrate life's special moments.

Perfect for: Buyers who want a diamond that symbolizes love, individuality, and lasting memories as much as it showcases beauty. 

Buying Tip: Look for a heart diamond with evenly rounded lobes and a symmetrical outline. A well-balanced shape is far more noticeable than chasing a slightly higher color or clarity grade.

Looking for a Vintage Inspired Diamond Instead?

Not every jewelry design starts with a round or oval diamond. Some projects need a shape that isn't commonly found in traditional jewelry stores. Whether you're restoring a family heirloom, designing an Art Deco inspired ring, or creating perfectly matched diamond earrings, specialty cuts open up possibilities that standard shapes simply can't.

Here are some unique options worth exploring.

1. Old European Cut Diamond

For Buyers Who Love Antique Character

If you're looking for a diamond that feels different from today's perfectly cut round diamonds, an old European cut is a great place to start. It's popular among buyers who love vintage inspired jewelry and want a diamond with its own personality.

Instead of the sharp sparkle you see in modern round diamonds, old European cuts produce larger, softer flashes of light that create a warm, old-world look. It's the perfect choice if you're designing a ring inspired by family heirlooms or classic antique styles.

Best for: Antique style engagement rings and heirloom inspired designs.

2. Old Mine Cushion Cut Diamond

The Vintage Diamond That Started It All

Old Mine Cushion diamonds are ideal for buyers who love the charm of antique jewelry without giving up the desire for a newly grown diamond. Their soft outline, higher crown, and unique faceting give them a completely different look from modern cushion cuts.

Rather than creating tiny flashes of light, they produce bigger, slower reflections that add depth and character. If your goal is to create a ring that looks like it has been passed down through generations, this cut is hard to overlook.

Best for: Victorian, Georgian and vintage inspired engagement rings.

3. Old Mine Cut Pear Diamond

Antique Beauty with a Distinctive Twist

If you love the shape of a pear diamond but want something less common, then old mine pear offers the best of both worlds. It combines the graceful outline of a pear with the softer faceting style found in antique diamonds.

The result is a diamond that feels unique from every angle. It's a popular choice for buyers creating one of a kind engagement rings or custom pendants that don't look like everything else available in the market.

Best for: Statement engagement rings and eye catching diamond pendants and necklaces.

Matching Pair Diamonds

When one diamond isn't enough, buying two diamonds sounds simple until you realise that matching them is much more than finding the same carat weight.

Professional jewelers compare dimensions, color, clarity, table size, and even how the diamonds reflect light. A pair that looks identical on paper can still appear different once set side by side.

That's why calibrated matching pairs are such a valuable option when creating jewelry that needs perfect symmetry.

Why This Matters When Choosing Loose Diamonds

The shape you choose is only part of the story. The best diamond is the one that suits the piece you're creating, your personal style, and how you'll wear it every day.

If you've already found a shape that catches your eye, the next step is understanding why buying a loose diamond first gives you more flexibility than choosing a ready made piece of jewelry. 

Why Buy a Loose Diamond Instead of Ready Made Jewelry?

When people first start shopping for diamond jewelry, they often head straight to engagement rings or earrings. But experienced buyers usually take a different route. They choose the diamond first.

Why? Because the diamond is the one part of your jewelry that can't be changed later without replacing it. Ring styles come and go, settings can be upgraded, and even the metal can be changed in the future. The diamond you choose, however, is the heart of the piece and the part you'll admire every day.

Buying a loose diamond also gives you far more transparency. Instead of judging a finished piece as a whole, you can compare the diamond's cut, color, clarity, carat weight, measurements, and certification before making your decision. It becomes much easier to understand exactly what you're paying for.

Another advantage that many buyers don't realise is flexibility. You might find the perfect diamond today but need more time to decide on the setting. Purchasing the stone first means you won't have to settle for a second-choice diamond simply because it's already mounted in a design you like.

Think of it this way. A jewelry setting can always be redesigned or upgraded years later, but replacing the center diamond usually means starting over. That's why many jewelers recommend choosing the diamond first and letting every other design decision revolve around it.

Tips for Choosing the Right Loose Diamond

Prioritize Cut Over Carat

A well-cut diamond reflects light better and often appears more brilliant than a larger diamond with an average cut. If your budget is limited, investing in a better cut usually makes the biggest visual difference.

Balance the 4Cs

There's no need to chase the highest grades in every category. Many buyers find better value by choosing a diamond with an Excellent Cut, G-H color, and VS1-VS2 clarity, while selecting the carat weight that suits their budget.

Always Buy Certified Diamonds

An independent grading report gives you confidence in what you're buying. Whether it's GIA or IGI certified, the report verifies the diamond's quality and makes comparing different stones much easier.
