1.5-2.0 Carat Uncut Rough White Lab Grown Hpht

HPHT stands for High Pressure High Temperature Process, which is a primary method used in laboratories to create diamonds. This diamond growth process requires exposing the carbon to extreme temperatures and pressures that mimic the extreme heat and pressure conditions found in natural diamond formation deep in the Earth.

A CVD diamond is a diamond created by a process called Chemical Vapor Deposition. This process begins with a  diamond seed crystal , typically from a high quality synthetic diamond, in a vacuum chamber. A natural gas, such as methane, is then pumped into the chamber and broken down into carbon atoms that accumulate on the crystal and form a diamond. In addition to natural gas, the crystal is treated with high temperatures and pressures within the chamber to remove any coloration and make the diamond colorless.
 

Better Value
Lab-grown diamonds have a high value because they are more affordable than natural diamonds of the same size and quality.These lab grown diamonds are nearly 30% cheaper than mined natural diamonds.

Excellent environment
Mining diamonds from the earth is fossil fuel-intensive, harmful to the environment, and increasingly unsustainable every year.Growing diamonds consumes a fraction of the energy and does not pollute the fragile ecosystems in rivers and lakes. The growth of diamonds requires only two main components: carbon and electricity.

Beauty & Quality
Grown diamonds and natural diamonds have the same composition, physical properties, chemical properties, optical properties, but their growth environment is different.
