What Are Lab-Grown Diamonds and How Do They Differ from Natural Diamonds ?

Lab-grown diamonds are real diamonds created in a controlled laboratory environment rather than formed naturally within the Earth.

They have essentially the same chemical composition and crystal structure as natural diamonds and can display the same exceptional brilliance.

The fundamental difference between a natural diamond and a lab-grown diamond is therefore not that one is “real” and the other is not.

Their most important differences are origin, rarity, method of production and market-value dynamics.

Are Lab-Grown Diamonds Real Diamonds?

Yes.

Lab-grown diamonds consist of crystalline carbon and possess essentially the same fundamental chemical, physical and optical properties as natural diamonds.

They should not be confused with diamond simulants such as cubic zirconia.

However, laboratory-grown and natural diamonds have different origins and should always be clearly identified and sold as distinct categories.

How Are Lab-Grown Diamonds Created?

There are two principal methods:

HPHT – High Pressure High Temperature

and

CVD – Chemical Vapor Deposition

HPHT uses extremely high pressure and temperature to create conditions in which a diamond crystal can grow.

With CVD, diamond growth takes place inside a specialized chamber, where carbon atoms are gradually deposited onto a diamond seed to form a larger crystal.

Both technologies can produce gem-quality diamonds suitable for fine jewelry.

How Are Natural Diamonds Formed?

Natural diamonds have a very different story.

They form through natural geological processes at considerable depths within the Earth under conditions of extreme pressure and temperature.

Their formation takes place over geological timescales.

This natural origin and limited availability contribute significantly to the rarity and individual character associated with natural diamonds.

Can You See the Difference with the Naked Eye?

In most cases, no.

A high-quality lab-grown diamond can visually resemble a natural diamond with comparable characteristics.

Reliable identification of origin requires specialized gemological techniques and equipment.

This is why independent grading and transparency from the seller are particularly important.

What Is the Price Difference?

This is one of the most significant differences.

Lab-grown diamonds are generally considerably less expensive than natural diamonds of comparable carat weight, color, clarity and cut.

As a result, within a particular budget, a buyer can often select a larger lab-grown diamond or higher color and clarity grades.

Their lower prices are related in part to their ability to be produced in controlled environments, allowing supply to expand through production.

Which Is Rarer?

The natural diamond.

Natural diamonds are a finite natural resource, and the availability of particular combinations of size and quality can be limited.

Lab-grown diamonds, in contrast, can be produced through technological processes.

This represents one of the fundamental distinctions between the two categories.

What About Resale Value?

This is an important consideration for buyers to understand.

No diamond should be purchased on the assumption of a guaranteed future return or predetermined resale price.

However, lab-grown diamond prices have experienced substantial declines as production technology has improved and available supply has increased.

Their potential future market value should therefore not be considered in exactly the same way as that of a natural diamond.

At Anweva, we believe this distinction should be clearly explained before a client makes a purchase.

Can Both Be Certified?

Yes. Both natural and laboratory-grown diamonds can be examined by recognized gemological laboratories.

Documentation for a laboratory-grown diamond should clearly identify its laboratory-grown origin.

At Anweva, we offer certified natural and lab-grown diamond options and provide clear information regarding the characteristics and origin of each stone.

Natural Diamond or Lab-Grown Diamond: Which Should I Choose?

The right choice depends on your priorities.

A lab-grown diamond may be appropriate if your priorities include:

• A larger carat weight within a particular budget

• Higher color or clarity grades at a lower price

• The appearance of a diamond without the price of a comparable natural stone

A natural diamond may be appropriate if you place greater importance on:

• Natural geological origin

• Rarity

• The uniqueness of a naturally formed gemstone

• Different long-term market dynamics

There is no single answer that is right for everyone.

There is, however, one principle that should apply to every diamond purchase: you should know exactly what you are buying.
