FAQs

A lab-grown diamond, also known as a laboratory-grown or laboratory-created diamond, is a genuine diamond created through advanced technological processes rather than formed naturally beneath the Earth’s surface.

Laboratory-grown diamonds have essentially the same chemical composition, crystal structure, optical characteristics, and physical properties as natural diamonds. (GIA 4Cs)

The distinction is one of origin, not identity.

A natural diamond is formed through geological processes over immense periods of time. A laboratory-grown diamond is created in a carefully controlled environment using sophisticated diamond-growth technology.

The result is a diamond worthy of the same attention to cut, proportion, polish, color, clarity, and craftsmanship that defines exceptional fine jewelry.

There are two principal technologies used to create laboratory-grown diamonds: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). (GIA 4Cs)

HPHT recreates some of the high-pressure and high-temperature conditions associated with diamond formation. A diamond seed and carbon source are subjected to carefully controlled conditions that allow diamond crystal to grow.

CVD uses a different approach. Inside a controlled chamber, carbon-containing gases are activated so that carbon atoms deposit onto a diamond seed and gradually form new diamond crystal, layer by layer. (GIA 4Cs)

Both technologies can produce gem-quality diamonds. The finished stone is then cut and polished to reveal the brilliance, fire, and scintillation that make diamonds so captivating.

Yes.

A laboratory-grown diamond is not a diamond imitation such as cubic zirconia or moissanite. It is diamond material created through a technological growth process.

Laboratory-grown diamonds have essentially the same chemical composition and crystal structure as natural diamonds and exhibit comparable optical and physical properties. (GIA 4Cs)

In other words, the distinction is where the diamond was formed—not whether it is a diamond.

For a luxury jewelry buyer, this means you can select a laboratory-grown diamond for its beauty, quality, proportions, craftsmanship, and personal meaning.

The fundamental difference is origin.

A mined, or natural, diamond forms through geological processes within the Earth. A laboratory-grown diamond is created using controlled technological processes.

Once polished, both can possess the characteristic brilliance, fire, hardness, and crystal structure associated with diamond. Specialized gemological equipment can identify whether a diamond is laboratory-grown or natural because each growth environment leaves distinctive characteristics. (GIA 4Cs)

For the wearer, the choice becomes less about appearance and more about origin, personal preference, and what the diamond represents to you.

Generally, not with the unaided eye.

A high-quality laboratory-grown diamond can have the same visual characteristics associated with a natural diamond, including brilliance and fire.

However, laboratory-grown diamonds can exhibit growth characteristics that allow trained gemologists and specialized instruments to identify their origin. GIA, for example, uses advanced testing and spectroscopy to distinguish laboratory-grown diamonds from natural diamonds. (GIA 4Cs)

This is why an independent diamond report can be an important part of a confident purchase.

Beauty is ultimately personal—but laboratory-grown diamonds can display the same fundamental optical properties associated with diamond.

Their beauty comes from the same essential elements that make any exceptional diamond captivating: cut, proportions, symmetry, polish, color, clarity, and light performance.

A beautifully cut diamond can return light with extraordinary brilliance and fire, regardless of whether its origin is geological or technological.

That is why we believe the most important question is not simply where was the diamond formed? but how beautifully was it cut, and how does it make you feel when you wear it?

Laboratory-grown diamonds can be independently evaluated by recognized gemological laboratories.

Organizations such as GIA provide laboratory-grown diamond services and reports or assessments that identify the stone as laboratory-grown and document relevant quality characteristics. (gia)

Depending on the laboratory and report type, documentation may include information relating to the diamond’s color, clarity, carat weight, measurements, growth method, and detectable treatments. (gia)

For significant purchases, we recommend reviewing the accompanying laboratory documentation and ensuring that the report number corresponds with the diamond being purchased.

The 4Cs—Cut, Color, Clarity, and Carat Weight—remain essential considerations when evaluating a diamond.

Cut influences how effectively a diamond interacts with light and is one of the most important factors in its visual beauty.

Color describes the degree of color present in a diamond.

Clarity refers to internal characteristics and surface features.

Carat Weight measures the diamond’s weight—not its visual size.

Together, the 4Cs provide a framework for understanding diamond quality and comparing stones. (GIA 4Cs)

But a truly exceptional diamond is more than four letters on a report. Proportion, symmetry, polish, optical performance, and the overall harmony of the stone all contribute to its beauty.

HPHT and CVD are the two principal technologies used to grow laboratory-grown diamonds.

HPHT diamonds are produced using high pressure and high temperature. The process uses a carbon source and diamond seed under carefully controlled conditions. (GIA 4Cs)

CVD diamonds are produced in a controlled chamber in which carbon-containing gases are activated and carbon deposits onto a diamond seed, allowing the crystal to grow layer by layer. (GIA 4Cs)

Neither term indicates that one is inherently a better choice. The individual diamond’s quality, characteristics, treatments, cut, and overall appearance should be evaluated.

For many consumers, laboratory-grown diamonds represent an appealing alternative because the diamond itself is not extracted through conventional mining.

However, ethical and environmental considerations are more nuanced than a simple label. The overall impact of a laboratory-grown diamond can depend on factors including the technology used, energy sources, manufacturing practices, and supply chain.

For that reason, responsible luxury should be grounded in transparency rather than sweeping claims.

We believe customers deserve clear information about what they are purchasing so they can make a choice that reflects their own values.

Laboratory-grown diamonds can offer advantages associated with avoiding the extraction of the diamond through conventional mining. However, it would be misleading to describe every laboratory-grown diamond as universally or automatically “eco-friendly” or “environmentally friendly.”

Energy consumption and manufacturing practices vary significantly between producers.

For this reason, environmental claims should be considered in the context of the specific diamond’s production and sourcing rather than treated as a universal characteristic of every laboratory-grown diamond. The FTC has specifically cautioned businesses against broad, unqualified environmental claims that cannot be substantiated. (Federal Trade Commission)

Laboratory-grown diamonds are not extracted from conflict zones through diamond mining because the diamond itself is produced in a laboratory.

However, we prefer precise language over broad ethical guarantees. A company’s broader supply chain, manufacturing partners, metals, gemstones, and sourcing practices can involve considerations beyond the origin of the diamond.

For consumers seeking responsibly sourced jewelry, transparency throughout the supply chain is the more meaningful standard.

A diamond should first and foremost be purchased for its beauty, craftsmanship, and meaning—not as a guaranteed financial investment.

The resale value of any diamond can vary depending on its characteristics, original purchase price, market conditions, demand, and other factors.

Laboratory-grown diamonds are generally offered at a different price point from comparable natural diamonds, which can allow buyers to consider larger stones or different quality characteristics within a given budget.

The true value of a diamond, however, is often far more personal than its resale price.

It is the ring worn through a lifetime, the anniversary remembered decades later, and the piece eventually passed to someone you love.

Yes. Laboratory-grown diamonds are available in an extraordinary range of shapes and cutting styles.

Popular choices include:

• Round Brilliant
• Oval
• Cushion
• Emerald
• Radiant
• Princess
• Pear
• Marquise
• Asscher
• Heart

Each shape has its own personality.

A Round Brilliant offers timeless symmetry and exceptional sparkle. An Oval can create an elegant, elongated appearance. An Emerald Cut emphasizes clarity and architectural beauty, while a Cushion Cut offers a softer, romantic character.

The perfect shape is ultimately the one that feels unmistakably yours.

Yes. Laboratory-grown diamonds can be found in a variety of colors, including traditional colorless and near-colorless stones as well as fancy-color diamonds.

Depending on the production process and any subsequent treatment, laboratory-grown diamonds may be available in colors such as yellow, pink, blue, and others.

When purchasing a colored laboratory-grown diamond, it is particularly important to understand whether its color is naturally developed during growth or the result of a post-growth treatment, as this can be documented by a gemological laboratory. (gia)

Yes.

Like natural diamonds, laboratory-grown diamonds can contain internal characteristics and surface features commonly referred to as inclusions and blemishes.

These characteristics can vary according to the growth method and individual stone. Clarity is therefore an important part of evaluating a laboratory-grown diamond.

Rather than viewing every inclusion as a flaw, it can be helpful to think of clarity as part of the individual character of the stone.

Yes. Laboratory-grown diamonds possess the fundamental hardness associated with diamond and rank 10 on the Mohs hardness scale.

This exceptional hardness makes diamond particularly suitable for jewelry designed for everyday wear, including engagement rings and wedding bands.

Nevertheless, hardness is not the same as indestructibility. Diamonds can still chip or fracture under sufficient impact, particularly around sharp corners or points.

A little care protects a lifetime of brilliance.

Absolutely.

A laboratory-grown diamond can be an extraordinary choice for an engagement ring.

Its combination of diamond hardness, brilliance, variety, and availability in a broad range of shapes and sizes gives couples remarkable freedom when creating a ring that feels personal.

Whether your vision is a classic solitaire, an elegant three-stone design, a modern halo, or a completely bespoke creation, a lab-grown diamond can become the centerpiece of a meaningful piece of fine jewelry.

The technology may be modern.

The emotion is timeless.

Yes.

Laboratory-grown diamonds can be incorporated into engagement rings, wedding bands, earrings, necklaces, bracelets, tennis jewelry, eternity rings, and other fine jewelry designs.

Their versatility makes them suitable for everything from understated everyday pieces to extraordinary statement jewelry.

For the modern collector, laboratory-grown diamonds offer another way to explore exceptional design, scale, color, and craftsmanship.

Your laboratory-grown diamond can be cared for much like a natural diamond.

For routine cleaning, use warm water, a small amount of mild soap, and a soft brush. Gently clean around the diamond and setting, rinse thoroughly, and dry with a soft cloth.

Avoid harsh household chemicals and abrasive materials.

For frequently worn jewelry—particularly engagement rings—we also recommend periodic professional inspection of the setting to ensure that the prongs and other components remain secure.

The diamond itself does not inherently become cloudy simply because it was laboratory-grown.

What can change is its surface appearance. Oils, cosmetics, lotions, soap, and everyday residue can accumulate on the diamond and reduce its brilliance.

Regular cleaning usually restores the stone’s sparkle.

If a diamond appears persistently cloudy even after cleaning, a professional jeweler or gemologist should examine it to determine whether the issue relates to the stone, a treatment, or the setting.

Yes.

A laboratory-grown diamond can generally be set, reset, or incorporated into a new jewelry design just as a natural diamond can.

An engagement ring can evolve with you. A classic solitaire can become a more elaborate setting. A treasured diamond can be transferred into a new piece. A family design can be reimagined for another generation.

The diamond remains the constant.

The setting can tell a new story.

Choosing a diamond is both an art and a science.

Begin with the qualities that matter most to you: shape, carat weight, color, clarity, cut, budget, and overall visual appearance.

Then look beyond the certificate.

Two diamonds with similar 4C grades can look remarkably different because of differences in proportions, symmetry, polish, and light performance.

For an important purchase, we recommend comparing the actual stones, reviewing the available laboratory documentation, and choosing the diamond that delivers the balance of beauty and value that feels right to you.

Because the perfect diamond is not necessarily the largest.

It is the one you cannot stop looking at.

For today’s jewelry buyer, laboratory-grown diamonds offer an intriguing combination of modern technology and timeless beauty.

They are genuine diamonds with essentially the same fundamental chemical composition, crystal structure, and physical and optical properties as natural diamonds. (GIA 4Cs)

They also provide extraordinary flexibility in choosing shape, size, color, clarity, and design.

But ultimately, choosing a diamond is not about following a trend.

It is about finding something beautiful enough to mark a moment that deserves to last.

Modern origin. Exceptional craftsmanship. Timeless meaning.

That is the promise of laboratory-grown diamond jewelry.
