WHAT ARE LAB GROWN DIAMONDS?

Lab-grown diamonds are diamonds that are created in a laboratory setting using advanced technology. They are chemically, physically, and optically identical to naturally-occurring diamonds, but are produced in a fraction of the time and cost. They are commonly referred to as "synthetic diamonds" or "cultured diamonds". They are used in jewellery and industrial applications, and are becoming increasingly popular as a more sustainable and ethical alternative to mined diamonds.

HOW ARE LAB GROWN DIAMONDS MADE?

Lab-grown diamonds are made using one of two methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

The HPHT method simulates the high pressure and high temperature conditions that occur in the Earth's mantle where natural diamonds form. This process starts with a small diamond seed, which is placed in a chamber with carbon-rich gases. The chamber is heated to a temperature of around 1500 degrees Celsius and subjected to pressures of around 5-6 GPa. The carbon atoms in the gases attach to the seed and slowly form a diamond crystal.

The CVD method involves using a microwave plasma to break down a carbon-rich gas (usually methane) into its individual atoms. These atoms then deposit onto a substrate, forming a diamond crystal.

Both methods produce diamonds that are chemically, physically, and optically identical to mined diamonds. The main difference is the growth environment, with lab-grown diamonds being made in a controlled laboratory setting.

WHAT IS THE DIFFERENCE BETWEEN THE METHODS?

Both the CVD and HPHT method have their own advantages and disadvantages. The choice of which method to use depends on the specific application and the desired properties of the diamond.

CVD method is known for producing high-quality, large-area, and low-defect diamond films, and is often used in industrial and scientific applications such as electronic devices, cutting tools and thermal management.

On the other hand, HPHT method is more versatile, it can produce diamonds of various colours and sizes, and is commonly used for producing diamond gemstones. Also it can produce high-quality diamond crystals with fewer defects, and it is able to produce larger diamonds than CVD method, which is desirable for certain types of jewellery.

In terms of cost, CVD method is relatively cheaper than HPHT method, but this can vary depending on the scale of production and the specific equipment used.

In summary, the choice of which method to use will depend on the specific application and the desired properties of the diamond. Both methods can produce high-quality diamonds that are identical to mined diamonds chemically, physically, and optically.

SO ARE LAB GROWN DIAMONDS CLASSED AS REAL DIAMONDS?

Yes, lab-grown diamonds are real diamonds. They are chemically, physically, and optically identical to naturally-occurring diamonds. They have the same crystal structure, refractive index, and hardness as mined diamonds. They are made of pure carbon, and they are composed of the same atoms and molecules as natural diamonds. The main difference between lab-grown diamonds and mined diamonds is their origin, lab-grown diamonds are created in a laboratory setting using advanced technology, while natural diamonds are formed in the earth's mantle over millions of years.

Lab-grown diamonds are also known as "synthetic diamonds" or "cultured diamonds". They are widely accepted in the diamond industry and can be used in jewellery, industrial and scientific applications. Some organizations such as the Gemmological Institute of America (GIA) and the International Gemmological Institute (IGI) also issue grading reports for lab-grown diamonds, which confirm their quality and characteristics

 

CHOOSING LAB GROWN OR NATURAL DIAMONDS

Both lab-grown diamonds and natural diamonds are real diamonds and have similar physical and optical properties. However, there are some differences between the two.

One of the main differences is the origin. Lab-grown diamonds are created in a laboratory setting using advanced technology, while natural diamonds are formed in the earth's mantle over millions of years.

Another difference is the cost. Lab-grown diamonds are generally less expensive than natural diamonds because they can be produced in a fraction of the time and cost. However, this can vary depending on the specific diamond and the scale of production.

Also, lab-grown diamonds are considered a more sustainable and ethical alternative to mined diamonds, as their production does not require the displacement of earth or harm to the environment.

Ultimately, the choice between a lab-grown or natural diamond will depend on personal preferences, budget and values. Some people prefer the natural origin of a diamond, while others prefer the ethical and environmental aspects of lab-grown diamonds. Both types of diamonds can be used in jewellery and have similar characteristics.
