Lab Grown Diamond

Context: The lab-grown diamond industry sees India playing a significant role, positioning itself as the world\'s second-largest producer of precious stones created in laboratories rather than extracted from the earth.

About:

Properties of Laboratory-Grown Diamonds	Description
Chemical, Optical, and Physical Properties	Essentially the same as natural diamonds, consisting of tightly-bonded carbon atoms and responding to light similarly. They are just as hard as natural diamonds.
Origin	Produced using specific technology to mimic the geological processes that grow natural diamonds
Diamond Simulant	Used to mimic the appearance of natural diamonds, including Moissanite, Cubic Zirconia (CZ), White Sapphire, YAG, and others.
Production Methods - High Pressure, High Temperature (HPHT)	Mimics the conditions under which natural diamonds are formed inside the earth. Involves extreme pressures and temperatures.
- Chemical Vapor Deposition (CVD	Grows laboratory-grown diamonds using moderate temperatures and lower pressures by depositing carboncontaining gas onto a diamond seed in a vacuum chambe
Applications -	- Used for industrial purposes such as machines and tools due to their hardness and strength. - Pure synthetic diamonds used in electronics as heat spreaders for high-power laser diodes, laser arrays, and high-power transistors
Production and Global Role	India produces over three million lab-grown diamonds annually and accounts for 15% of global production.
Quality Improvement through HPHT	Lower-quality diamonds, whether natural or laboratorygrown, can undergo the HPHT process to enhance color. This process can also be used to produce colored diamonds.
Color Alteration via HPHT	The HPHT method can be utilized to change the color of diamonds, including pink, blue, or yellow, providing flexibility in meeting market demands.
