HPHT Lab Grown Diamonds Description

 

The Lab Grown Diamonds are produced in the laboratory. The laboratory uses advanced technology and equipment to reproduce the formation enviornment of natural diamonds. By using fine diamond seeds to induce natural diamond crystallization, Lab Grown Diamonds with the same physical, chemical and optical properties as natural diamond can be cultivated on the ground. Lab Grown Diamonds are real diamonds.

Lab Grown Diamonds are 100% real diamonds and 100% eco-friendly diamonds. It's very cost effective and more affordable.

HPHT stands for high pressure and high temperature. In order to grow high performance high temperature diamond, a small diamond seed was put into carbon, diamond is made of carbon. Diamond seeds are exposed to extreme heat and pressure to replicate diamonds in a natural way. They grow underground. Diamond seeds exposed above 1100 degrees, pressure about 1.5 million Pounds per square inch. The carbon melts around the seeds and forms diamonds. Then it cools and the diamond forms.

Chemical vapor deposition (CVD) is a method to grow diamond from hydrocarbon gas mixture. The flexibility and simplicity of CVD devices explain the popularity of CVD growth in laboratory research. The advantages of CVD diamond growth include the ability to grow diamond on large area and different substrates, as well as the fine control of chemical impurities and properties of the diamond.

The growth of CVD involves the preparation of substrates, injecting different amounts of gases into a chamber and energizing them. The substrate preparation includes selecting suitable materials and crystal orientation; When cleaning, diamond powder is often used to grind non diamond substrate; Optimized substrate temperature (about 800 ℃) In the growth process, through a series of test run. These gases usually include a carbon source, usually methane, and a typical ratio of 1:99 hydrogen. Hydrogen is essential because it selectively corrodes non diamond carbon. These gases are ionized into chemically active radicals in the growth chamber by microwave power, hot filament, arc discharge, welding torch, laser, electron beam or other methods.

HPHT Lab Grown Diamonds Introduction

 

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
