Why lab-grown diamonds?

Lab-Grown Diamond , also known as "laboratory diamond" and "synthetic diamond". Recognized by many international institutions and laboratories, like natural diamonds, lab-grown diamonds also come with certificates. Since cultured and natural diamonds have the same chemical and physical properties, almost no one, including jewelers, can tell whether a diamond is natural or cultured with the naked eye.

The first lab-grown diamonds were launched on the market in the late 1990s. Today, more than 30 years later, they have still not completely replaced natural diamonds. However, there are still more than 100 companies involved in the production of lab-grown diamonds. Why is this happening? Woolen cloth?

How to grow lab-grown diamonds?

Cultured diamonds are pure carbon diamonds grown under strictly controlled laboratory conditions, simulating the natural growth process of diamonds on the earth. They have the same composition, atomic structure and crystal habits as natural diamonds.

The most commonly used methods in lab-grown diamonds are chemical vapor deposition (CVD) and high pressure and high temperature (HPHT). The following will briefly explain how these two methods are used to grow diamonds.

  • Chemical vapor deposition (CVD):
    In this technique, a small piece of diamond seed is placed in a growth chamber and a carbon-containing gas is introduced. The gas is ionized using microwaves or other methods, causing the carbon atoms to separate and deposit on the seed crystal. Carbon plasma is generated in diamond seeds, allowing carbon atoms to accumulate into stone, forming diamonds.
  • High pressure and high temperature method (HPHT):
    This method replicates the natural environment in which diamonds form deep within the Earth's mantle. Diamond "seeds" are placed in a vacuum growth chamber, heated to over 1,000 degrees Celsius, and rotated at 2,000 miles per hour, allowing carbon atoms to form on the seeds. Then, the seeds will be placed in a high-pressure and high-heat environment and hydrogen gas will be added to stabilize the growth of diamonds.

When a diamond is removed from the growth chamber, a lab-grown diamond undergoes the same cutting and polishing process as a natural diamond to reveal its sparkle and fire.

Can’t lab-grown diamonds symbolize love?

The article "Why Diamonds" explains why diamonds can symbolize love, but can lab-grown diamonds also enjoy the same iconic meaning?

Both natural diamonds and cultured diamonds have the same physical composition, hardness, refractive index, and fire color. Their crystal structures are also three-dimensional face-centered cubic carbon atoms, and they are also at the tenth level of the Mohs hardness scale.

Indestructible characteristics are likened to unbreakable love.

Both shine equally, the reflection angle after light enters is also total internal reflection, and cultivated diamonds also have the optical effects that natural diamonds should have.

The shining characteristics are likened to brilliant love.

The history of natural diamonds is even older than humans, with most being created between one and three billion years ago. With today's (2023) technology, it only takes three to five days to produce a lab-grown diamond, which is even shorter than the time it takes for an embryo to form.

A human life is made up of trillions of moments. Nietzsche's "Eternal Return" implies that our life is actually repeated infinitely, so the infinitely repeated present is even longer than a lifetime. Nietzsche hopes that we learn to be happy now, because our happiness is not based on it. Length, but depth.

Love that lasts for a long time is indeed enviable, but can beautiful love only be defined by the length of time?

Born Diamond doesn’t have the answer, and we think everyone’s answer is different. Because of this, adhering to Born Diamond's doctrine - "Diamond for the People" , we provide a variety of choices, hoping to provide a product that is most suitable for customers through our services.
