What is lab-grown diamond, which is gaining attention around the world?

On this page, we will tell you about the value and charm of lab-grown diamonds, as well as the advantages and disadvantages of purchasing them, as we know from DIALLLURE, which handles both lab-grown diamonds and natural diamonds.

1.What is Lab Grown Diamond?

Lab-grown diamonds are real diamonds that are created in a lab using innovative technology.

This technology recreates the same environment in which diamonds are formed in their natural underground environment, allowing them to be grown artificially.

Lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds, making them a high-quality, sustainable option.

This relationship is often compared to a flower.





例えば薔薇を例にとるとラボグロウンダイヤモンドは野性の薔薇。対するラボグロウンダイヤモンドは温室育ちの薔薇です。 どちらも見た目にはバラであることに違いはありません。



For example, if you take a rose as an example, a lab-grown diamond is a wild rose. Lab-grown diamonds, on the other hand, are roses grown in greenhouses.

Moissanite and cubic zirconia are artificial flowers, so the viewer can tell at a glance that they are not diamonds, but diamonds and lab-grown diamonds are impossible to tell apart visually. Currently, even commercially available diamond testers give the same diamond judgment, so it is necessary to use advanced appraisal equipment to make the judgment.

Lab-grown diamonds have the same visual, physical, chemical, and optical properties as natural diamonds, and because they are ethical and have excellent cost performance, they have become a new option for engagement rings in Europe and the United States as an alternative to natural diamonds. We are increasing our market share.

At DIALLURE, once you have decided on a design that meets your needs, we will set the diamond of your choice, whether natural or lab-grown.

2. The charm of lab-grown diamonds

What is the charm of lab-grown diamonds? it is

① It is ethical ② You can get beautiful TYPE IIA that does not contain any impurities ③ It has better cost performance

There are three main points.


First, let's talk about ethics. Lab-grown diamonds do not require underground mining, so they are environmentally friendly . There are also no conflict diamond issues that plague diamonds.

*DIALLURE only handles conflict -free natural diamonds, excluding conflict diamonds.

Additionally, Lab Grown Diamonds has succeeded in creating TYPE IIA diamonds that contain only 2% of impurities present in diamonds . TYPE IIA is a diamond that does not contain any impurities such as nitrogen or boron, and is extremely rare in the world of natural diamonds .

In addition, since lab-grown diamonds have inclusions that are easier to control than natural diamonds, it is possible to create diamonds with high clarity in the VVS and VS classes.

Finally, regarding cost performance. If it is a large carat, you can purchase it for less than half the price compared to natural . For this reason, it is a great advantage to be able to choose larger, higher grade diamond jewelry.

3. Disadvantages of lab-grown diamonds

There are not many in terms of disadvantages.

One thing to note is that there is currently no resale market for lab-grown diamonds. For this reason, we recommend natural diamond jewelry when purchasing for asset purposes.

However, diamonds smaller than 0.5 carat are the most widely distributed in Japan. These have little resale value. As for assets, they must be over 1 carat and have been certified by GIA, an international appraisal agency, as having a high grade of 4C. If you are considering a diamond less than 1 carat, I think this is a disadvantage that you do not need to think about too much.

4. The future of lab-grown diamond jewelry

Lab-grown diamonds are already becoming popular in Europe and America as a new alternative to natural diamonds. At the 2022 Antwerp Diamond Center conference, it was announced that 10% of American engagement rings have already been replaced by lab-grown diamonds .

On the other hand, because diamonds are indistinguishable from natural diamonds, high ethical standards and reliability are more important than ever in the diamond jewelry industry.

We at DIALLURE are members of the Japan Grown Diamond Association and the Japan Laboratory Grown Diamond Association , and have begun establishing rules that allow our customers to shop with peace of mind.
