CVD Single Crystal Diamonds Description

Due to the inherent transparency of CVD Single Crystal Diamonds in a wide wavelength range, optical characterization has long been a common method to characterize inclusions, impurities and color defects. 
CVD Single Crystal Diamond has the widest optical transparent band of all known solids, ranging from 0.22um to far infrared. Only the intrinsic vibration absorption band with intensity between 2.5 and 7um interferes with the transmittance of CVD Single Crystal diamond in the infrared region. CVD Single Crystal Diamond is transparent in ultraviolet, visible and infrared spectra, which provides many opportunities for lattice defects to reveal the optical activity of electronic and vibrational transitions. Large band gap energy (5.49 EV) is a particularly favorable condition for luminescence, because the ground state and excited state are required to be in the band gap for radiative electron transition. The high mechanical hardness and thermal conductivity of CVD Single Crystal Diamond greatly support its optical applications, making CVD Single Crystal Diamond optics very stable and wear-resistant in many aspects. When discussing the optical properties of materials, we should carefully consider their optical centers, because their properties and abundance determine almost all the optical properties of materials. In addition, the optical center content is the main parameter to characterize the optical properties of materials. So far, more than 150 vibration centers and more than 500 electron optical centers have been detected in CVD Single Crystal Diamond, with the spectral range of 20-0.17um.

CVD Single Crystal 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.
