Lab Created Diamonds Description

 

Lab created diamond is a small diamond as the seed, through the laboratory to simulate the growth of natural diamonds to grow. It has the same physical, chemical and optical properties as natural diamond, and the hardness is 10. There are two ways to produce and grow diamonds. One is high temperature and pressure, or HTHP. This method is through the six-side top press (figure below). To put it simply, it has six different sides and three directions, namely up and down, left and right sides and front and rear sides. The carbon source and metal catalyst are placed in each other's growth chamber, and the carbon heating rod is used to heat up, forming an environment of 55,000-60,000 atmospheric pressure and temperature above 1400℃. The device can grow crystals of synthetic diamonds that look exactly like natural diamonds.

Another way is the chemical vapor deposition (CVD), the method must first have a seed of natural diamond chips, also need to use the methane gas, methane under the action of energy, forming a carbon plasma, the plasma like dust, slowly through the air to the seed of diamond chips, bit by bit deposition. Carbon atoms from methane gas are deposited on seed diamonds, which grow at a rate of 0.007 millimeters per hour. In a laboratory environment, one-carat diamonds can be grown in a week. Their hardness and purity are comparable to natural diamonds, but the price is only one-sixth of that of natural diamonds. The purity and clarity of diamonds grown by this method are particularly high, and currently occupy a large share of the gem-grade lab-grown diamond market.

The composition and hardness of lab grown diamonds and natural diamonds are the same. Simply put, they are not afraid to scratch, even if you scratch them with sandpaper or a knife.

Growing diamonds is cheap and good. There is little difference between lab-grown diamond and natural diamond in appearance, but it can be found that lab created diamond of the same quality grade is much cheaper than natural diamond, and some even have one-fifth of the price of natural diamond.
Lab grown diamond and natural diamond from the appearance of the point of view is not very different, but from the quality of the cultivation of diamond quality will be better, mainly because of the cultivation of diamond can be a little quality control, the general output of diamond quality is better. And natural diamond as a result of do not have external force action, direct natural form, come quality grade can be grasped more hard so, bring about diamond of a high quality rare world to beg hard.
