Rough Lab Grown Diamonds Description

Many people refer to Lab Grown Diamonds as 'fake' diamonds, but this is not accurate. The carbon based chemistry of Rough Lab Grown Diamonds means that they are actually "real" diamonds - unlike cubic zirconia or moissanite.
These diamond simulators are also made in the laboratory, but they are not made of carbon atoms, so they are not real diamonds.
Simulates are not as shiny and shiny as real diamonds. There are also differences in hardness. Diamond scores 10 on the Mohs hardness scale, while moissanite scores 9-9.5 and cubic zirconia scores 8.
What is a lab-grown diamond?
Lab diamonds are real diamonds. Lab-grown diamonds after polishing and cutting are no different from natural diamonds.Carbon is the main element of natural and laboratory-grown diamonds.
The HPHT synthesis method is a more traditional diamond cultivation method that uses molten metal alloys such as iron (Fe), nickel (Ni) or cobalt (Co) to form diamonds.
The CVD synthesis method is a relatively new method of cultivating diamonds. The vacuum chamber is filled with carbon-containing gas. A carbon plasma is formed at the bottom of the vacuum chamber. The plasma is continuously deposited on the carbon bottom layer at the bottom of the pressure chamber. For several weeks, the resulting flake crystals usually have black rough edges, and the crystals often appear brown, but they can be removed by heat treatment.
Since 2014, the production of laboratory-grown diamonds has progressed rapidly. Today, the cost of cultivating diamonds in the laboratory is significantly lower than that of natural diamonds. And synthetic diamonds of all sizes can be cultivated in the laboratory, from extremely small diamonds (round diamonds with a diameter of 0.5 mm) to more than 10 carats, it is not difficult to reach. In particular, small diamonds (melee diamonds) have been mass-produced and used in jewelry setting.

Rough Lab Grown Diamonds Introduction

Rough Lab Grown Diamond is a polycrystalline diamond made of diamond crystals with a diameter of 10 to 30 nanometers. In the early stage, man-made diamonds showed a light color of sugar due to the nitrogen atoms in the air entering into the diamond crystal. Through the improved production method of scientists, there is no difference between man-made diamonds and natural diamonds in appearance now.
