FAQ

Are lab-grown diamonds real diamonds?

Yes, lab-grown diamonds are real diamonds with the same physical, chemical and optical properties as diamonds.

How are lab-grown diamonds made?

It is made mainly in two ways.

The CVD method is suitable for producing high-quality diamonds. A thin diamond seed is placed in a device called a chamber and a gas containing carbon is blown onto it. The carbon accumulates and forms an atomic bond with the seed, causing it to grow into a large diamond.

The HPHT process involves exposing carbon to high temperatures and pressures, mimicking the process by which natural diamonds are formed in the earth.

DIALLURE diamonds are beautiful, high-grade lab-grown diamonds made using the CVD method.

How do you determine the quality of a lab-grown diamond?

DIALLURE's lab-grown diamonds are mainly those that have been certified by the world-renowned GIA and IG diamond certification agencies.

The appraisal method is the same as for natural diamonds, using the 4Cs.

At DIALLURE, we have established high standards for handling diamonds that exceed those of overseas high-end jewelers.

Do lab-grown diamonds have any asset value?

Unlike diamonds, there is currently no resale market for lab-grown diamonds.

However, diamond jewelry includes the jeweler's profits, such as brand fees and labor costs, and it is said that unless the diamond is of a museum quality, its value will drop from the moment it is purchased.

If you are looking for value in your jewelry, we recommend purchasing gold.

From this perspective, it is believed that there is no need to give much consideration to the asset value of diamonds set in a typical engagement ring.
