How Are Lab-Grown Diamonds Made? | Explained by Chicago Jewelry Experts

Lab-Grown Diamonds: The Future of Fine Jewelry in Chicago

The modern process of creating diamonds in laboratories forms the foundation of this article.

When searching for the perfect engagement ring or wedding band in Chicago, you’ll likely come across lab-grown diamonds during your searches for “jewelry stores near me,” “custom jewelers Chicago,” or “engagement rings Chicago.”

The jewelry industry is undergoing a remarkable transformation as lab-grown diamonds offer sustainable origins, exceptional quality, and more accessible pricing. At Wedding Bands & Co., located in downtown Chicago, we guide couples through every step of their ring journey — beginning with understanding the diamond creation process.

Just as a ring consists of distinct components — from the head and setting to the shank — the creation of a lab-grown diamond follows a precise, multi-stage process.

Below, we explore how lab-grown diamonds are made, their similarities to natural diamonds, and why Chicago couples are increasingly choosing them for engagement rings and wedding bands.

1. The Essence of Lab-Grown Diamonds

At the heart of every ring lies the diamond — a symbol of love and strength. Lab-grown diamonds are created in controlled environments that replicate the Earth’s natural conditions, resulting in authentic diamonds identical in chemical composition, physical structure, and brilliance to mined diamonds.

Each lab-grown diamond is graded by the same 4Cs — Cut, Color, Clarity, and Carat — and certified by leading gemological institutes such as GIA and IGI. The only true difference lies in their origin: one formed deep within the Earth, and the other crafted through advanced technology.

2. The Two Methods of Diamond Growth

Just as the band supports a ring’s structure, two main scientific methods form the foundation of lab-grown diamond creation:

a. High Pressure, High Temperature (HPHT)

This method recreates the intense heat and pressure found deep within the Earth:

• A tiny diamond “seed” is exposed to carbon at temperatures over 1,500°C and pressures exceeding 1.5 million psi.
• Over several weeks, carbon atoms bond to the seed, growing it into a larger diamond crystal.

b. Chemical Vapor Deposition (CVD)

CVD allows greater control and precision, similar to custom-setting a ring:

• A thin diamond seed is placed inside a chamber filled with a carbon-rich gas, typically methane.
• Heated plasma breaks down the gas, allowing carbon atoms to settle on the seed and form a pure diamond crystal over time.

The CVD method often produces diamonds with superior clarity and symmetry — ideal for fine jewelry and engagement rings.

3. Ethical & Environmental Integrity — The Sustainable “Band”

The sustainability of lab-grown diamonds serves as the moral foundation that connects modern values with timeless beauty.

Traditional diamond mining has long been associated with issues such as:

• Environmental damage and habitat destruction
• High carbon emissions
• Unsafe labor practices
• Lack of supply chain transparency

Lab-grown diamonds offer a responsible alternative:

• No mining or land displacement
• Minimal environmental impact
• Full traceability from seed to finished stone

These factors make lab-grown diamonds the ethical choice for Chicago couples who care about sustainability and transparency in their jewelry.

4. Precision Craftsmanship — From Seed to Sparkle

Creating a diamond requires the same meticulous precision as crafting the head and prongs of a ring. Once grown, lab diamonds undergo the same expert processes as mined diamonds:

• Skilled artisans cut facets to maximize brilliance
• Advanced technology refines proportions for optimal light performance
• Final polishing reveals the signature sparkle of a perfectly finished diamond

At Wedding Bands & Co., our jewelers design settings that enhance each diamond’s radiance — from timeless solitaires to intricate halo and vintage-inspired styles.

5. Price Breakdown — The Value of Smart Luxury

Lab-grown diamonds deliver extraordinary beauty and value. On average, they cost 40–60% less than mined diamonds of comparable quality, allowing couples to:

• Choose a larger stone within budget
• Select higher color or clarity grades without overspending
• Allocate more of their budget toward unique settings or personalized details

For instance, while a 1-carat mined diamond may cost between $6,000–$8,000, a lab-grown equivalent of the same grade may range from $3,000–$5,000 — freeing funds for custom engravings, hidden halos, or designer-inspired touches.

6. Myth vs. Reality — Where Romance Meets Innovation

A common misconception is that lab-grown diamonds lack the romance of mined diamonds. In truth, they embody both science and love — born from innovation, yet destined to symbolize emotion.

Each lab-grown diamond begins its journey in a lab but fulfills its purpose when chosen as part of your love story.

In Chicago, more couples are embracing this modern approach, valuing transparency, ethical sourcing, and collaboration with local jewelers to design one-of-a-kind engagement rings.

7. Beyond Jewelry — The Many Uses of Lab-Grown Diamonds

The purity and strength of lab-grown diamonds make them valuable far beyond fine jewelry. They are used in:

• Industrial cutting and drilling tools
• Advanced electronics and semiconductors
• Scientific and medical instruments

Their versatility showcases their superior quality — not as replacements, but as advancements in diamond technology.
