Lab-grown diamonds are artificial diamonds that are created in a laboratory.
For this reason, some people call natural diamonds "fake," but is this actually the case?
In the United States, where lab-grown diamonds are becoming increasingly popular, they are said to have the same taxonomic and scientific properties as natural diamonds.
Lab-grown diamonds are widely accepted as being "real diamonds," and many people are interested in them.

1. Taxonomically and scientifically authentic

Lab-grown diamonds are evaluated using the same 4C method as natural diamonds.

Evaluation criteria are used.

Both are made up of carbon and have the same crystal structure, a face-centered cubic lattice.

It has the same material properties as glass, with a refractive index of 2.417 , a Mohs hardness of 10 , and a dispersion of 0.044 .

It is generally considered difficult to distinguish with the naked eye, and even with a magnifying glass it is difficult to determine the difference.

They are equal diamonds except for where they were made.

2. What is the difference between lab-grown diamonds and natural diamonds?

So, what is the difference between lab-grown diamonds and natural diamonds?

It all comes down to where the diamonds are made and the shape of the rough .

Natural diamonds are minerals formed when carbon crystallizes under high temperatures and pressure deep underground in the earth.

Diamonds buried underground are pushed up to the surface by volcanic activity and other factors, where they are mined.

Lab-grown diamonds, on the other hand, are created in a laboratory .

Carbon, the building block of diamond, is crystallized using advanced technology to precisely form extremely thin diamond layers one by one.

Natural diamonds are mainly isometric rough stones with octahedral or dodecahedral shapes. Lab-grown diamonds grow mainly as cubic rough stones due to the crystallization method.

3. Why are lab-grown diamonds attracting attention?

It's at an affordable price.

When compared to natural diamonds of the same quality,

Lab-grown diamonds can be purchased for about half the price .

For large diamonds such as 1 carat,

About one third .

Large natural diamonds are out of reach, but people want to wear a diamond at least once in their life. Lab-grown diamonds are widely loved by people like that.

4. Can you choose the color of diamonds?

Lab-grown diamonds are also recommended for colored diamonds.

Some high-quality colored natural diamonds can be priced at tens of millions of yen. However, since lab-grown diamonds are artificially created in a lab, you can enjoy them for just a few hundred thousand yen.

We are now in an age where rare and valuable colored diamonds can be achieved through lab-grown diamonds. Why not consider colored diamonds as one of your options?

The advent of lab-grown diamonds has made diamonds more accessible and enjoyable.

At BRIGHT & BREEZY , we believe that lab-grown diamonds bring "bright and smart enjoyment" and make everyday life richer and more beautiful.
