Lab-grown diamonds

WHAT ARE LAB GROWN DIAMONDS(LGD)?

Laboratory-grown Diamonds looks as same as Real Diamonds which are mined from the Earth and they are also called as Created Diamond, Man-Made Diamond and Cultured Diamonds.

There are two main methods for the production of lab-grown diamonds, HPHT (high pressure, high temperature) and CVD (chemical vapor deposition). HPHT stones are made by subjecting carbon in the form of graphite to extreme heat and pressure by means of a mechanical press and electrical current; CVD diamonds are ‘grown’ at much lower pressures by building up layers on a base surface from a surrounding carbon plasma cloud.

We develop oneself in service that is very well tune up to the specifications of the buyer. Our team of experts provides you with the proper servicing and product you’re looking for, with minimal human error.

Now, We have reached at the place of professional manufacturer and supplier of Laboratory-Grown Diamonds. All Lab-Grown diamonds ranging from VVS1 to SI clarity, 0.005 ct to 2.00 ct size are directly produced by our manufacturing factory.

The quality and mastery of our jewelry are the same as most of the leading brands in the world but at a fraction of the price. Because we manufacture our own jewelry, we don’t have to pay commissions and profits to other distributors and can pass the savings along to our customers.

ADORNET JEWELS offers excellent value and are more affordable than natural diamonds of comparable size and quality.

From the manufacturing of Lab Grown Diamond to manufacturing of Mined Diamond's jewelry, altogether without any middle man and that’s how we can guarantee our very competitive prices

HOW ARE LAB CREATED DIAMONDS MADE

Diamonds are made from highly organized carbon. Natural Diamonds take around 1 billion to 3 billion years to form. Lab Grown Diamonds are created by applying heat and pressure to a diamond seed. This chamber replicates the conditions which are present inside the earth’s surface.

The diamonds take around six to eight weeks to form. The diamonds are then cut, polished and graded. It is virtually impossible for the naked eye to tell the difference between lab grown and mined diamonds. They are a revolution in the diamond industry. Lab Created Diamonds many advantages over mined diamonds.
Chemical Vapour Deposition(CVD):
CVD Process is used to create gem quality diamonds.CVD process uses ultra pure rich carbon gases in a controlled environment/chamber. Some CVD Processes are mentioned below:
  • Low-pressure CVD (LPCVD)
  • Ultrahigh vacuum CVD (UHVCVD)
  • Plasma-enhanced chemical vapour deposition (PECVD)
  • Microwave Plasma Vapour Deposition (MPCVD)
High Pressure High Temperature (HPHT):
In HPHT the machines have the ability to build up the pressure of almost 60,000 atmospheres and temperature of 2,500°C.It contains all the elements that are needed to grow a diamond. It includes a tiny diamond seed, highly refined graphite and a catalyst mixture containing metals and powders. The catalyst inside react to added heat and pressure resulting in molten form. The molten catalyst solution causes the graphite (carbon) to dissolve. After this the cooling
process takes place. It requires a controlled environment to produce a gem quality diamond.

Two main press designs are used to supply required temperature and pressure.
  • Belt Press: High Pressure is created by using two high strength pistons which provide equal pressure in opposing directions.
  • Cubic Press:-This technique uses many pistons that provide pressure from many different directions.
