  • Many choices due to many colors

The introduction of artificial diamonds brings many benefits to life because it helps reduce pressure on natural diamonds, adorns more luxurious and noble beauty for owners and fashionistas. promoting the development of science and technology and high-tech industries.

How to make Artificial Diamond?

In recent times, many people tend to use artificial diamonds, but surely not many people know about the methods of making artificial diamonds. Read on to see more about 2 methods of synthesizing artificial diamonds!

  • High pressure high temperature method (English name is called high pressure high temperature): This method has the advantage of creating an environment similar to the natural diamond regeneration environment in the ground through the use of high pressure and temperature.
  • Chemical vapor deposition method (English name is called chemical vapor deposition): This method will use a plasma heat beam to split gas molecules and obtain carbon atom deposition, whereby artificial diamonds form on the existing nuclei.

In addition, researchers at the University of North Carolina in the US have developed a method to produce a form of carbon (the team named this material Q-carbon) that closely resembles diamond at room temperature. no need for high temperature, high pressure).

Difference between synthetic and natural diamonds

Natural diamonds and man-made diamonds have similar characteristics. Therefore, many people do not know how to distinguish these two materials. Follow the quick test below!

Check diamond clarity with a magnifying glass

For synthetic diamonds, when it is necessary to check the clarity through a magnifying glass, the viewer will see the outside smoothness along with the beautiful sharp cut and especially the inside without impurities.

As for natural diamonds, they are formed in a harsh natural environment, undergo high temperature and pressure, so they will definitely leave some impurities. In addition, when examining with a magnifying glass, viewers can easily see the true beauty of diamonds in nature through the rough surface that is true to natural origin.

How to look under the light to check the refraction

In addition to the magnifying glass test, people also use the way of looking under the light to check the refraction because when compared through the refraction of light, it will determine the beauty of precious diamonds.

Natural diamonds possess outstanding sparkling beauty with a refraction of 2,417 diopers.
As for synthetic diamonds, the refractive index is only 1,217 diopers (1.98 times less than natural diamonds), this ratio is considered to be less likely to reflect back, this is a big difference compared to diamond. natural diamond.

Rub sandpaper on the surface to check the hardness

Diamond is known for its high hardness. Therefore, natural diamonds possess a hardness of up to 10 on the Mohs scale, especially natural diamonds do not appear scratched when sanding the surface with sandpaper. This demonstrates the incredible perfection of natural diamonds.

Besides, synthetic diamond leaves scratches when sanded because it only has a hardness of 8.5, so the hardness is relatively unstable. Therefore, it is necessary to preserve as well as know how to preserve natural diamonds to avoid scratches.

Price comparison between synthetic and natural diamonds

There is a big difference between the value of man-made diamonds and natural diamonds. Natural diamonds are said to be worth over 100 million/1 carat, which is quite a high price compared to many people’s income.

However, if the economy is not much, artificial diamonds are also an option for many people who want to own this sparkling and luxurious gift.

What is the difference between synthetic diamonds and simulated diamonds?

Synthetic diamonds and simulated diamonds are two types of lab-made diamonds, but there is a difference between them. That is:

Simulated diamond is what it sounds like because it looks like a diamond (same hardness, same dispersion) but is judged not to be a real diamond. Imitation diamonds have a perfect surface finish, so they are used in jewelry making, usually Rhinestone and cubic zirconia.

As for artificial diamonds, many experts believe that there is no real artificial diamond trading, the current advertising offers are actually just for the purpose of blowing up prices and misleading consumers.

Distinguishing artificial diamond from synthetic diamond imitation stone

Currently, many types of jewelry are advertised as artificial diamonds, but on the market today, they are actually often fitted with synthetic diamond imitation stones, which are CZ (Cubic Zirconia) and Moissanite stones.

  • Chemical structure: Artificial diamond is made of Carbon and CZ stone has a chemical structure of ZrO2 + Y302 and Moissanite is SiC.
  • Color: Artificial diamond has colorless, yellow, brown, blue, red, orange, black, green. And CZ stone has many other colors, while Moissanite is colorless.
  • Stiffness: Artificial diamond has a hardness of up to 10, while CZ stone has a hardness of 8.5 and Moissanite is 9.5.
  • refractive index: Artificial diamond is 2.417 and CZ stone is 2.18, Moissanite stone is 2,670.
    Density: Artificial diamond is 3.52, but CZ stone is from 5.50 to 6.0, Moissanite is 3.218 – 3.22.
  • Fracture degree: Synthetic diamonds and CZ will have no cracks, while Moissanit will have few cracks.
  • Thermal conductivity: Artificial diamond and Moissanite will conduct heat well while CZ stone will not conduct heat.
  • Dispersion coefficient: Artificial diamond is 0.044 and CZ stone is 0.060, Moissanite is 0.313.

How to distinguish artificial diamond from CZ . stone

CZ stone (also known as Cubic Zirconia): A popular stone as an imitation diamond, used since 1977.

In addition, there are many ways to distinguish artificial diamonds and CZ stones, readers can refer to a few of the following ways:

Method 1: In terms of proportions

Apply the formula: Weight = Diameter (mm) x diameter (mm) x height (mm) x 0.0061.

If the output is close to 3.52, we determine it is a diamond. And if the result is from 5.50 – 6.0, it is CZ stone.

Method 2: Use sandpaper to sand

If it is an artificial diamond, there will be no scratches and CZ stones will appear scratches, the surface of the stone will be blurred.

Method 3: In terms of thermal conductivity

CZ stones do not conduct heat, while synthetic diamonds are good conductors of heat. Therefore, we can use a specialized test pen called Presidium Multi Tester.

How to distinguish artificial diamond from Moissanite stone?

A simple way to distinguish man-made diamonds from Moissanite is through the refraction of light. Applying this method shows that: Artificial diamond has a short, colorless light beam, while Moissanite has a long and colorful light beam.

How much does a synthetic diamond cost?

To be able to create an environment close to nature to cultivate artificial diamonds will require high investment costs. Many people believe that such expensive investment makes the cost of artificial diamonds will be high and even higher than natural diamonds.

The selling price of an artificial diamond can range from several tens of millions to several billion dong depending on the quality as well as other characteristics (transparency, color, quality through the cut, shape, weight,…)
