NATURAL DIAMONDS

What Is a Natural Diamond?

A natural diamond is a naturally occurring crystalline form of carbon that develops deep within the Earth under extreme geological conditions. Over enormous periods of geological time, carbon atoms arrange themselves into the crystal structure associated with diamond.

Natural diamonds eventually reach the Earth's surface through geological processes and are recovered through mining. The rough material is then sorted, cut and polished before being graded and eventually sold as jewelry.

One of the major attractions of a natural diamond is its geological history. Every natural diamond has a story connected to the Earth's formation and the conditions under which that individual stone grew.

LAB-GROWN DIAMONDS

What Is a Lab-Grown Diamond?

A lab-grown diamond is a diamond produced through a controlled technological process rather than formed naturally underground. Modern laboratories and manufacturing facilities can grow diamonds using processes that recreate conditions suitable for diamond growth.

The two major methods used for gem-quality lab-grown diamonds are HPHT, which stands for High Pressure High Temperature, and CVD, which stands for Chemical Vapor Deposition.

The important distinction is origin. Calling a diamond "lab-grown" identifies how it was produced; it does not mean that the stone is a diamond simulant such as cubic zirconia.

Good to Know

Lab-grown diamonds are diamonds. Their origin is different from natural diamonds, but they are not the same thing as diamond simulants.

COMMON QUESTION

Are Lab-Grown Diamonds Real Diamonds?

✓

Yes — lab-grown diamonds are diamonds.

The important difference is not whether the stone is a diamond, but where and how it formed. Lab-grown diamonds are created by people using diamond-growth technology, while natural diamonds develop through natural geological processes.

Lab-grown diamonds should also not be confused with simulants. Materials such as cubic zirconia and moissanite can resemble diamond but have different chemical and physical properties.

LAB TECHNOLOGY

HPHT vs CVD Lab-Grown Diamonds

HPHT and CVD are two different technological approaches to growing laboratory diamonds. The growth method alone should not be treated as a simple quality ranking. The finished diamond still needs to be evaluated on its own characteristics.

HPHT

High Pressure High Temperature

HPHT technology uses high pressure and high temperature conditions to facilitate diamond growth.

  • Uses controlled pressure and temperature
  • Can produce gem-quality diamonds
  • Growth environment differs from natural formation
  • Professional laboratories can identify growth characteristics
IMAGE PLACEHOLDER HPHT Diamond Growth
CVD

Chemical Vapor Deposition

CVD uses a controlled chamber and carbon-containing gases to grow diamond material layer by layer.

  • Uses a controlled growth chamber
  • Diamond material grows from a seed
  • Allows controlled production
  • Growth characteristics can be detected by laboratories
IMAGE PLACEHOLDER CVD Diamond Growth
IDENTIFICATION

Can You Tell a Lab-Grown Diamond From a Natural Diamond?

In many cases, you cannot reliably determine a diamond's origin just by looking at it. Because lab-grown diamonds can have essentially the same optical and physical characteristics as natural diamonds, professional identification can require specialized equipment.

A loupe or casual visual inspection should not be treated as a definitive origin test.

Visual Inspection Not a reliable origin test by itself.
Diamond Report Check the documented origin and grading information.
Professional Laboratory Advanced testing can identify growth characteristics.

SPARKLE & BEAUTY

Do Lab-Grown Diamonds Sparkle as Much as Natural Diamonds?

Origin alone does not determine how much a polished diamond sparkles. Cut quality, proportions, faceting, polish, symmetry and the way the diamond interacts with light are much more important considerations.

IMAGE PLACEHOLDER Diamond Sparkle Comparison
01

Cut

A well-cut diamond can return light effectively and appear bright.

02

Proportions

Pavilion, crown and overall proportions influence visual performance.

03

Polish

Surface finish affects how cleanly light interacts with the stone.

04

Symmetry

Facet alignment contributes to the visual balance of the diamond.

DURABILITY

Are Lab-Grown Diamonds as Durable as Natural Diamonds?

◆

Diamond Hardness

Diamond is extremely hard, and both natural and lab-grown diamonds are diamond materials. This makes both suitable for jewelry intended for regular wear.

✦

Hardness Is Not Toughness

Hardness describes resistance to scratching. Toughness relates to resistance to breaking or chipping. A diamond can still chip if struck in a vulnerable area, particularly around certain shapes or settings.

Engagement Ring Tip

Your diamond's setting matters too. Protective settings can help shield vulnerable areas of the stone during everyday wear.

PRICE

Lab-Grown vs Natural Diamond Price

Price is one of the biggest reasons shoppers compare lab-grown and natural diamonds. Comparable lab-grown diamonds are generally sold at lower prices than natural diamonds, although the actual difference varies by stone, retailer, certification, market conditions and date.

LAB-GROWN
Typically Lower Upfront Cost

A lower purchase price can allow some buyers to allocate more of their budget toward carat size, cut quality, color, clarity or the ring setting.

NATURAL
Typically Higher Upfront Cost

Natural diamonds generally command higher prices because their supply is connected to naturally occurring geological resources and an established natural-diamond market.

PRICE CHART PLACEHOLDER Replace with your current verified market-price comparison.
Important: Never publish a fixed percentage or "average price" as a timeless fact. Diamond prices change and vary considerably based on quality, certification, retailer and market conditions.
UNDERSTANDING VALUE

Why Are Lab-Grown Diamonds Cheaper?

01

Controlled Production

Lab-grown diamonds can be produced in controlled facilities rather than depending exclusively on naturally occurring diamond deposits.

02

Manufacturing Scalability

Technological production can be scaled as manufacturing capacity and market demand change.

03

Market Competition

Multiple producers and retailers compete within the lab-grown segment, influencing market pricing.

04

Different Supply Dynamics

Lab-grown diamonds and natural diamonds operate under different supply structures, which affects pricing.

RESALE & VALUE

Lab-Grown vs Natural Diamond Resale Value

One of the most misunderstood areas of diamond buying is resale value. A diamond's retail price should not be treated as a guaranteed resale price.

The amount a seller may receive later can depend on market conditions, the original purchase price, the stone's characteristics, grading, demand, retailer policies and the type of secondary market involved.

Lab-grown diamonds have also experienced changing market dynamics as production technology and supply have developed. That means buyers should be especially cautious about treating a lab-grown diamond as a guaranteed financial investment.

Natural diamonds also should not be marketed as guaranteed investments. Buying a diamond for its beauty, meaning and personal value is very different from buying a traditional financial asset.

ETHICS

Are Lab-Grown Diamonds More Ethical?

There is no single answer that applies to every diamond. Ethical considerations depend on the specific supply chain, production practices, energy sources, labor conditions and sourcing standards.

Lab-Grown Considerations

  • Production takes place in controlled facilities
  • Energy source can affect environmental considerations
  • Factory and labor practices still matter
  • Supply-chain transparency is important
  • Production technology continues to evolve

Natural Diamond Considerations

  • Mining practices differ by operation and location
  • Land and environmental impact can vary
  • Labor practices and community impact matter
  • Responsible sourcing standards are important
  • Supply-chain transparency matters
Avoid the Simple "Eco-Friendly" Label

Do not assume that every lab-grown diamond has the same environmental footprint or that every natural diamond has the same mining impact. Ask where the diamond comes from and how it was produced.

ENVIRONMENT

Lab-Grown vs Natural Diamonds: Environmental Considerations

Environmental comparisons require more than simply asking whether a diamond was mined or laboratory-grown. The full production system, including energy use, mining activity, transportation and manufacturing, can influence the overall impact.

01

Energy

Lab-grown production requires energy, and the source of that energy can affect environmental considerations.

02

Mining

Natural diamond production involves mining, with environmental considerations that vary between operations.

03

Transportation

Both categories can involve multiple stages of transportation and processing before reaching consumers.

04

Supply Chain

Responsible sourcing and transparent supply chains are important considerations for either choice.

SIZE FOR YOUR MONEY

Can You Get a Bigger Diamond for the Same Budget?

This is one of the strongest practical reasons shoppers compare lab-grown and natural diamonds.

Because comparable lab-grown diamonds are generally less expensive, some shoppers may choose to allocate the difference toward a larger carat weight, higher color or clarity, a more elaborate setting, or simply keep the remaining budget.

However, size should not be the only goal. A poorly cut larger diamond may look less attractive than a smaller diamond with stronger proportions and light performance.
