A diamond is one of the most enduring symbols of love, commitment, and life’s most meaningful moments. In recent years, lab-grown diamonds have offered a new way to experience that enduring beauty — one grounded in modern science, thoughtful sourcing, and exceptional value. Understanding what these stones are, how they’re made, and how they compare to mined diamonds can help you make a choice you’ll feel confident about for a lifetime.

What Exactly Is a Lab-Grown Diamond?

A lab-grown diamond is a real diamond. It is not a simulant like cubic zirconia or moissanite — it is chemically, physically, and optically identical to a diamond formed deep within the earth. The difference lies entirely in origin: one formed over billions of years beneath the earth’s surface, the other grown in a controlled laboratory environment over a matter of weeks.

Two primary methods are used to grow diamonds in a laboratory setting:

  • High Pressure, High Temperature (HPHT): This process replicates the extreme conditions under which natural diamonds form, subjecting a carbon source to intense heat and pressure until a diamond crystal grows.
  • Chemical Vapor Deposition (CVD): A carbon-rich gas is introduced into a chamber, where it breaks down and carbon atoms are deposited layer by layer onto a diamond seed, gradually building a crystal.

Both processes yield genuine diamonds. A gemologist cannot distinguish a lab-grown diamond from a mined one with the naked eye, and even under magnification, the differences are structural rather than visual.

How Lab-Grown Diamonds Compare to Natural Diamonds

When placed side by side, a high-quality lab-grown diamond and a high-quality natural diamond are visually indistinguishable. Both are graded using the same criteria — cut, color, clarity, and carat weight — by respected gemological laboratories such as the GIA (Gemological Institute of America) and IGI (International Gemological Institute). At M.S. Brown Jewelers, the lab-grown diamonds we carry come with proper certification so you always know exactly what you’re purchasing.

Where the two differ most meaningfully is in price and in the long-term resale market. Lab-grown diamonds typically cost significantly less per carat than comparable mined diamonds. This price difference has little to do with quality and everything to do with supply: lab-grown diamonds can be produced in greater volume, reducing scarcity. For many buyers, this represents an opportunity — a larger stone, a more intricate setting, or a higher color and clarity grade than their budget might otherwise allow.

The Ethical and Environmental Considerations

For many of our customers, the appeal of lab-grown diamonds goes beyond price. Traditional diamond mining, while subject to increasing regulation and industry oversight, can carry environmental and humanitarian concerns depending on the source region. Lab-grown diamonds sidestep questions of origin entirely.

That said, it’s worth approaching environmental claims with nuance. Growing diamonds in a laboratory does consume significant energy, and the environmental footprint depends largely on whether the facility uses renewable energy sources. If ethical sourcing and environmental impact are priorities for you, it’s worth asking your jeweler about the specific origins and production practices of the stones they carry — a conversation we welcome at either of our locations.

Choosing the Right Diamond for Your Needs

Whether a lab-grown or natural diamond is the right choice depends on your priorities, and there is no single correct answer. Consider the following:

  • Budget and size: If you want the largest, most brilliant stone your budget allows, lab-grown diamonds offer exceptional value per carat.
  • Sentiment and tradition: Some customers feel a deep connection to the natural origin of a mined diamond — its geological age and rarity carry personal meaning. That is a completely valid reason to choose natural.
  • Investment considerations: Natural diamonds have historically held value better than lab-grown stones, whose prices have declined as production has increased. If long-term resale value matters to you, this is worth factoring in.
  • Customization: Lab-grown diamonds are available in a wide range of cuts, sizes, and even fancy colors, making them a versatile option for custom design work.

At our Wildwood and Cape May Court House showrooms, we carry both certified natural and lab-grown diamonds and are happy to walk you through the differences in person, without pressure.

Caring for Your Lab-Grown Diamond

Because lab-grown diamonds share the same hardness and durability as natural diamonds — a 10 on the Mohs scale — they require the same care. Clean them periodically with warm water, mild dish soap, and a soft brush. Avoid exposing them to harsh chemicals, and store them separately from other jewelry to prevent surface scratching. Have settings inspected by a jeweler every year or two to ensure prongs remain secure — a simple step that protects a significant investment. Our team offers professional cleaning and inspections as part of our ongoing commitment to the pieces we sell.

Frequently Asked Questions

Are lab-grown diamonds considered “real” diamonds?

Yes. Lab-grown diamonds have the same chemical composition (pure crystallized carbon), the same optical properties, and the same hardness as naturally mined diamonds. They are graded and certified by the same gemological laboratories and are recognized as real diamonds by the FTC and the broader jewelry industry.

Can I get a lab-grown diamond certified?

Absolutely. Reputable gemological institutions such as the GIA and IGI issue grading reports for lab-grown diamonds, just as they do for natural stones. These reports document the diamond’s cut, color, clarity, carat weight, and origin. When purchasing a lab-grown diamond at M.S. Brown Jewelers, we ensure that significant stones come with proper documentation.

Will a lab-grown diamond lose its sparkle over time?

No. A lab-grown diamond’s optical properties do not change with age. Like any diamond, it may accumulate oils and residue from daily wear, which can be easily remedied with regular cleaning. The stone itself will not cloud, fade, or diminish in brilliance.

Can lab-grown diamonds be used in custom jewelry and engagement rings?

Yes, and they are an excellent choice for custom work. Because they are available in a wide range of sizes, shapes, and qualities, lab-grown diamonds offer considerable flexibility for custom designs. Our team at M.S. Brown Jewelers provides custom design and engraving services, and we’re experienced in working with both natural and lab-grown stones to bring your vision to life.

Whether you’re exploring lab-grown diamonds for the first time or weighing them against a natural stone for an engagement ring, our team is here to help you think it through. Stop in at either of our Jersey Shore locations — in Wildwood on Pacific Avenue or in Cape May Court House — and we’ll take the time to answer your questions, show you stones side by side, and help you find something you’ll treasure for years to come. There’s never any pressure, just honest guidance from people who genuinely love what they do.
