Lab Created Diamonds: What Doumato Jewelers Wants You to Know Before You Buy

If you've been shopping for an engagement ring or a special piece of fine jewelry lately, you've probably run into the term "lab created diamonds" more than once. At Doumato Jewelers, we get asked about them almost every single day, and it's easy to see why. Lab created diamonds (sometimes called lab grown diamonds or lab diamonds) have gone from a niche curiosity to one of the most popular choices in the diamond industry, and the reasons behind that shift are genuinely worth understanding before you make a purchase.

So let's talk about what lab created diamonds actually are, how they're made, how they stack up against mined diamonds, and why so many customers walking into Doumato Jewelers are choosing them for engagement rings, anniversary bands, and everyday fine jewelry.

What Exactly Is a Lab Created Diamond?

A lab created diamond is a real diamond. That's the part people are often surprised to hear. It's not a simulant like cubic zirconia or moissanite — it's made of the exact same material as a mined diamond: pure crystallized carbon. The only real difference is where it comes from. Instead of forming over billions of years deep in the Earth's mantle, a lab grown diamond is grown inside a controlled facility over the course of a few weeks.

There are two main methods used to grow diamonds today:

CVD (Chemical Vapor Deposition): A thin diamond seed is placed inside a vacuum chamber filled with carbon-rich gas. As the gas heats up, carbon atoms settle onto the seed layer by layer until a full diamond crystal forms.

HPHT (High Pressure High Temperature): This method recreates the natural conditions found deep inside the Earth by exposing a carbon source to intense heat and pressure, essentially compressing the growth process that would normally take eons into a matter of weeks.

Both processes result in a diamond that shares the same chemical structure, the same hardness, and the same brilliance as a natural stone. In fact, gemologists need specialized lab equipment just to tell the two apart — the naked eye simply can't do it.

How Do Lab Created Diamonds Compare to Natural Diamonds?

This is the question we hear most at Doumato Jewelers, and the honest answer is: they're remarkably similar in almost every way that matters to how the stone looks and wears.

• Hardness: Both natural and lab grown diamonds score a perfect 10 on the Mohs scale, meaning they're equally durable for everyday wear.
• Brilliance and fire: Lab diamonds and mined diamonds share the same refractive properties, so the sparkle you see is identical.
• Grading: Lab created diamonds are graded using the same 4Cs system — cut, color, clarity, and carat — and can be certified by the same respected labs, including GIA and IGI.
• Price: This is where things really diverge. Lab grown diamonds typically cost significantly less than a natural diamond of comparable size and quality, which means your budget can stretch further toward a bigger stone, a better cut, or a higher clarity grade.
• Origin and rarity: Natural diamonds are geologically rare and take billions of years to form. Lab diamonds can be produced on demand, which is part of why they're priced so differently.
• Resale value: It's worth being upfront about this one. Lab created diamonds currently hold much less resale value than natural diamonds, since they aren't limited by geological scarcity. If long-term resale is a major priority for you, that's a conversation worth having with our team before you buy.

Why Customers Are Choosing Lab Created Diamonds

At Doumato Jewelers, we've watched more and more customers gravitate toward lab created diamonds, and it usually comes down to a mix of practical and personal reasons:

More diamond for your budget. Because lab diamonds cost less to produce, you can often get a noticeably larger stone or a higher-quality cut for the same price as a smaller natural diamond.

Ethical peace of mind. Lab grown diamonds carry no conflict-origin concerns and no ties to the labor and environmental questions that sometimes surround traditional mining. For couples who want their ring to reflect their values, that matters.

Consistency and quality control. Because lab diamonds are grown in a controlled environment, manufacturers can produce stones to a precise specification, which often means fewer inclusions and more consistent color grading.

A modern story to tell. Plenty of our customers simply love the idea that their diamond represents where technology and craftsmanship meet. It's a forward-looking choice for a forward-looking relationship.

Is a Lab Created Diamond Right for You?

There's no universally "correct" answer here — it really comes down to what you value most. If you're drawn to the idea of a stone that took billions of years to form deep within the Earth, and long-term resale value is important to you, a natural diamond might be the better fit. If you'd rather maximize size, clarity, and budget while making an ethically conscious choice, a lab created diamond is hard to beat.

Either way, the most important thing is buying from a jeweler who's transparent about what you're getting, how it's graded, and what certification comes with it. That's exactly the approach we take at Doumato Jewelers — every diamond we offer, lab created or natural, comes with clear grading information so you can make the choice that's right for you with total confidence.
