Picking a diamond for an engagement ring is supposed to feel like a joyful milestone — but for many couples, it turns into hours of research, conflicting opinions, and second-guessing. Between sourcing questions, budget realities, and the sheer number of options, it's easy to lose sight of what actually matters: a ring that reflects your relationship. At Old Main Gem Co, we walk couples through this decision every week, and we're breaking down exactly what you need to know about natural and lab-grown diamonds so you can choose with confidence.
What Are Lab-Grown Diamonds, Really?
Lab-grown diamonds are not imitations, simulants, or substitutes — they are genuine diamonds in every measurable sense. They share the same crystal structure, the same fire and brilliance, and the same hardness as their mined counterparts. The only true distinction lies in how they come into existence.
Rather than forming over millions of years under intense heat and pressure deep within the earth, lab-grown diamonds are cultivated in advanced facilities that replicate those same natural conditions on a much shorter timeline. The carbon atoms arrange themselves into a diamond crystal just as they would underground — the process is simply guided rather than left to geological chance.
Our team in Draper, Utah works extensively with lab-grown stones because they open the door for couples to build a ring that's both beautiful and aligned with their personal values, all without sacrificing quality or craftsmanship.
Why Our Clients Often Choose Lab-Grown
When couples come to us undecided, a few advantages tend to tip the scale toward lab-grown diamonds:
- Ethical, traceable origins — every stone comes from a controlled, transparent process
- A lighter environmental footprint compared to traditional diamond mining
- Greater value per carat, often allowing for a larger or more elaborate stone at the same budget
This added flexibility is often what makes the biggest difference. Couples who choose lab-grown diamonds frequently tell us they feel free to go bigger on the center stone, invest more into a custom setting, or simply walk away knowing they made a choice rooted in their own priorities.
Natural Diamonds: The Case for Tradition
There's no denying the romance behind a natural diamond. Each one began forming long before recorded history — shaped by pressure and heat over millions of years before finally reaching the surface. For many couples, that origin story carries real emotional weight, evoking a sense of permanence, rarity, and connection to generations past.
For others, the decision leans more practical. Questions of budget, transparency in sourcing, and overall value often steer couples toward a lab-grown stone instead. Neither path is more "correct" than the other — what matters is which story resonates with you as a couple.
A Pattern We See Often in Our Showroom
It's common for couples to walk in set on a natural diamond, only to reconsider once they see what a lab-grown stone can offer at the same price point. Many discover they can achieve a larger carat weight, a more intricate setting, or simply more breathing room in their budget — all while getting a stone with identical sparkle and strength.
On the other hand, plenty of couples remain firmly committed to natural diamonds, and we're just as enthusiastic about helping them find a stone that honors that tradition. Our role isn't to steer you toward one option — it's to make sure whichever path you choose is one you feel completely confident in.
How to Decide: Three Questions Worth Asking
If you're still on the fence, these questions can help bring clarity:
- Does ethical sourcing and sustainability matter to you? Lab-grown diamonds may be the better fit.
- Do you want to stretch your budget toward size or design? Lab-grown stones generally offer more value per dollar.
- Are you drawn to the rarity and history behind a natural stone? A mined diamond may hold more meaning for you.
It's worth noting that the Gemological Institute of America (GIA) confirms natural and lab-grown diamonds share identical physical, chemical, and optical properties. In other words, this isn't a question of which diamond performs better — it's entirely a matter of personal preference and what feels right for your story.

Frequently Asked Questions
Is a Lab-Grown Diamond an Actual Diamond?
Yes. Lab-grown diamonds carry the exact same chemical composition, hardness, and optical brilliance as natural diamonds. Even trained gemologists cannot distinguish between the two without specialized equipment — to the eye, they are indistinguishable.
Are Lab-Grown Diamonds as Durable as Natural Ones?
Absolutely. Both score a 10 on the Mohs hardness scale, meaning a lab-grown diamond will hold up to daily wear just as well as a natural one. Decades from now, it will look just as radiant as the day it was set.
Will I Really Save Money With a Lab-Grown Diamond?
In most cases, yes. Lab-grown diamonds typically cost significantly less per carat than natural stones of comparable quality, which means more room in your budget for size, cut, or a custom design. We love helping couples use that extra flexibility to create a ring that's distinctly their own — without ever compromising on quality.
The Right Choice Is the One That Feels Like You
At Old Main Gem Co, we believe an engagement ring should tell your story, not simply follow convention. Whether that story is rooted in heritage and rarity or in ethical sourcing and modern value, both paths lead to a diamond worth celebrating.
If you're still weighing natural against lab-grown, we'd love to help you explore both in person. Visit our Draper showroom, ask every question on your mind, and see the difference for yourself — no pressure, just honest guidance.
In the end, the best diamond isn't the one everyone expects you to choose. It's the one that holds your story every time it catches the light.
