Why Lab-Grown Diamonds So Expensive?

Why Are Lab-Grown Diamonds Still Expensive?

If you're shopping for a custom engagement ring in Chicago, you’ve probably heard of lab-grown diamonds. They’re dazzling, environmentally conscious, and often more affordable than their mined counterparts. But one of the most common questions people have is:
“If they’re made in a lab, why are lab-grown diamonds still so expensive?”
It’s a fair question—and the answer lies in understanding both the diamond itself and the entire process behind creating and customizing a ring. In this article, we’ll break down the key reasons why lab-grown diamonds carry a premium price tag, and how Chicago’s jewelry scene adds value to your purchase.

First: What Are Lab-Grown Diamonds?

Let’s clear up a common misconception: lab-grown diamonds are real diamonds.
Unlike diamond simulants such as cubic zirconia or moissanite, lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. The only true difference is their origin.
While natural diamonds are formed deep within the earth and mined, lab-grown diamonds are created in controlled lab environments using one of two main techniques:

• HPHT (High Pressure, High Temperature)
• CVD (Chemical Vapor Deposition)

These methods replicate the intense heat and pressure that forms diamonds underground—just in a lab, and usually with less environmental disruption.

The Center Stone: The Star (and the Cost Driver)

Whether a diamond is lab-grown or mined, the center stone is typically the most expensive element of an engagement ring. Its size, brilliance, and quality determine the overall visual impact—and price.
So even if your diamond was grown in a lab, the larger and cleaner it is, the more it will cost.

Why Lab-Grown Diamonds Can Still Be Pricey

1. The Technology Behind Them Isn’t Cheap
Growing diamonds in a lab sounds simple, but it requires multi-million-dollar equipment, precise scientific conditions, and highly trained engineers. These facilities need to be meticulously maintained to ensure quality and consistency.
That infrastructure—and the skilled labor involved—adds cost to each diamond that’s grown.
2. Supply is Still Catching Up
While lab-grown diamonds are more accessible than ever, they’re not produced at unlimited volume. In fact, many suppliers still grow diamonds in small batches to maintain quality control.
Here in Chicago, most reputable jewelers partner with trusted lab-diamond providers who are carefully vetted, and this exclusivity can drive prices up.
3. Graded Just Like Natural Diamonds
Lab-grown diamonds go through the same rigorous grading system as mined diamonds, assessed by the 4Cs:

• Cut
• Color
• Clarity
• Carat weight

So, a 1.5ct D color, VS1 clarity lab diamond with an Excellent Cut will still be considered a premium stone—and priced accordingly. Just because it’s lab-grown doesn’t mean it’s cheap if it’s top-tier quality.
4. Flawless Stones Are Still Rare
Even in labs, it’s tough to grow perfect diamonds. Most stones have some degree of inclusions or color tint, so when a high-clarity, colorless stone does emerge, it’s valuable—regardless of its origin.

The Setting: Why Local Chicago Craftsmanship Matters

The diamond is only part of the picture. A huge factor in the final price of your ring is the custom setting—especially when crafted right here in Chicago.
At Wedding Bands Company, and other jewelers in the city’s historic Oak Street district, rings are often handmade by local artisans using high-quality materials like:

• 18K gold or platinum
• Pavé diamonds, hidden halos, or vintage-inspired detailing
• Hand engraving and intricate under-gallery designs

When you choose custom, you’re not only paying for materials—you’re investing in craftsmanship, expertise, and a one-of-a-kind piece made just for you.

So Why Buy Lab-Grown Diamonds in Chicago?

Shopping locally offers big advantages:

• You can see diamonds in person and compare lab vs. natural stones.
• Local workshops mean shorter lead times on custom designs.
• Appointments are personalized— and many are free, educational, and no-pressure.

Whether you book a virtual consult or stop by our Oak Street showroom, you're getting expert support from jewelers who live and work in the community.

The Role of Branding and Marketing

Let’s not ignore the impact of marketing. Lab-grown diamonds are often positioned as:

• “A modern, ethical choice”
• “Luxury without compromise”
• “Grown for you—not mined”

From celebrity endorsements to sleek packaging, lab diamonds are marketed as premium, purposeful pieces. That luxury image boosts their perceived value—and their price.

Will Prices Go Down in the Future?

Yes, but not overnight. As lab technology advances and more suppliers enter the space, prices for smaller diamonds may drop. But premium lab diamonds—especially 1.5ct+ with excellent clarity and color—will still command higher prices due to limited supply and demand.

Final Thoughts: Are Lab-Grown Diamonds Worth It?

Absolutely—once you understand the full picture.

• You're paying for technology, rarity, grading, and design—not just the “lab-grown” label.
• You can get an ethically sourced, stunning ring at a more accessible price point.
• You’re supporting local talent when you shop custom in Chicago.
