Lab Grown Diamond Shapes: Why They’re Changing the Jewellery Game

When you picture a diamond, what comes to mind? A sparkling round cut that looks straight out of a movie proposal scene? Or maybe a square princess cut with sharp, bold edges? Here’s the fun part—you don’t actually need to mine the earth anymore to get that sparkle. Lab created diamonds are rewriting the rulebook. And the best bit? They’re real diamonds, just born in a different way.

Diamonds With a Story (That Doesn’t Involve Mining)

Think about it: for years, diamonds carried this almost mythical backstory. Formed deep in the earth over billions of years. Dug up, cut, polished, sold. Romantic? Maybe. But also expensive, complicated, and—let’s be honest—a little messy when it comes to ethical sourcing.

Now enter lab grown diamond shapes. Instead of waiting for the planet to do its thing, scientists figured out how to speed up the process in controlled labs. No giant mines. No guesswork. Just technology meeting romance.

And honestly, there’s something kind of cool about telling your partner, “This diamond was created with science.” Feels modern. Feels intentional.

The Shapes People Are Actually Loving

Here’s where it gets interesting. With mined diamonds, you were usually limited by what nature gave you. With lab created diamonds, you’ve got a little more flexibility. The sparkle is the same, but the shape selection? Oh, it’s wide open.

Some of the most popular lab grown diamond shapes right now:

• Round Brilliant – The forever classic. If you don’t want to overthink, go round. It catches light like crazy.
• Oval – Slim, elegant, and makes your fingers look longer. Celebrities love this one.
• Princess Cut – Square edges, bold vibes. Perfect if you’re not into “soft and subtle.”
• Emerald – That vintage, art-deco look. Think Great Gatsby with a modern twist.
• Pear Shape – Half round, half pointy. Honestly underrated, but looks stunning in minimalist rings.
• Heart Cut – Cheesy? Maybe. But if you’re the hopeless romantic type, why not?

You might be surprised how many couples are moving away from the “default” round and choosing shapes that match their personality. That’s the magic of this trend—it’s personal.

Why Lab Grown Diamonds Feel Different (In a Good Way)

Here’s a question: would you rather have a diamond that looks flawless, fits your budget, and doesn’t leave you questioning where it came from… or one that comes with a vague origin story?

That’s why lab created diamonds are winning people over. They’re typically 30–40% less expensive than mined diamonds. Which means if you’ve got a budget of $5,000, you can either:

• Buy a smaller mined stone.
• Or buy a bigger, higher-quality lab grown one.

Most people go for the second option. Honestly, who wouldn’t?

And let’s not forget: lab grown diamonds are chemically and physically identical to mined ones. Same sparkle. Same hardness. The only difference is the origin story.

How They’re Made (Without the Boring Science Lesson)

Okay, quick crash course—no need for a lab coat.

1. Start with a Seed – Scientists use a tiny diamond seed as the foundation.
2. Simulate Earth’s Magic – They recreate the high heat and pressure conditions found deep underground.
3. Carbon Builds Up – Over weeks, carbon atoms layer on top of that seed, growing into a full diamond.
4. Cut + Polish – Just like mined diamonds, they’re shaped into brilliant cuts and polished for maximum shine.

So basically, it’s nature sped up with technology. And the end product? Indistinguishable from the “traditional” version.

The Local Angle: Why People Everywhere Are Paying Attention

Walk into any jewellery store today and you’ll probably hear someone ask, “Do you have lab grown options?” That question didn’t even exist ten years ago.

In places where engagement ring culture is huge (like the U.S., Europe, and increasingly in Asia), couples are starting to see lab created diamonds as the smarter, more thoughtful choice. They’re not just thinking about price, but about ethics, sustainability, and frankly… bragging rights.

Let’s face it—saying “My diamond is conflict-free and eco-friendly” is a pretty good flex.

Final Thoughts

At the end of the day, jewellery isn’t just about sparkle. It’s about the story you’re telling. And lab grown diamond shapes give you the freedom to pick a cut that actually feels like you, without breaking the bank or second-guessing the ethics.
