Frequentlt Asked Questions

The term CVD (Chemical Vapor Deposition) is suggestive of chemical and vaporization processes taking place in a controlled chemical reaction when methane gas is subjected to high pressure and high temperature under ideal catalyst in a laboratory, the carbon atoms of this gas start to break off and vaporize.

Since the process is carried out in a closed chamber, all the vaporized atoms eventually start settling down, which also looks like snowflakes falling during a snowfall.

People often confuse the term Synthetic with artificial. When Lab-grown diamonds are called Synthetic diamonds, it is not suggestive of its artificial nature. Synthetic diamond is to signify its development in man-made laboratories rather than under the earth's crust. Lab-grown diamonds have all the properties similar to naturally occurring diamonds, including its optical angle and other chemical and physical properties.

The resale value of any diamond depends on its quality and strength. Lab-grown diamonds are structurally, chemically and optically identical to earth-mined diamonds. So the resale value of both these is similar as well. However, it is interesting to note that the resale value of natural diamonds has fallen in the recent times due to the status of market values.

The Federal Trade Commission or FTC has recently included the mention of Lab-grown diamonds in its description of diamonds. Apart from that, the supply of naturally occurring diamond is much more than its actual demand leading to a drastic drop in its resale value.

In this situation, all the advantages seem to be shifting in favor of lab-grown diamonds, and its resale value is also noticeably going up.

The ideal temperature to obtain one of the finest quality CVD diamonds is 600-800 degrees of Celsius.

The process of development of this precious gemstone is quiet slow, but it is definitely worth the wait. The deposition rate of carbon atoms is ranged somewhere between 0.1 to 10 microns hourly.

The idea choices of substrates for CVD are diamonds pieces, silicon carbide, silicon oxynitride, silicon dioxide, titanium nitride, carbon fiber, nanofibers, nanotubes, and filaments. The basic two requirements for a substrate to be ideal for the fabrication of man-made diamonds are, it shouldn't be a carbon absorbent, and it should be able to withstand the high pressure and high-temperature conditions.

DLC is the short form for Diamond-like Carbon. Instead of using a crystal as a lattice as in the CVD process, DLC includes the deposition of atoms in a haphazard network. This amorphous solid is no diamond and the term ‘like' says it all in the word DLC.

Naturally occurring diamond is undoubtedly one of the finest work by nature. Its clarity, color, shine, and strength are worth applause. However, the lab-grown diamonds also possess the same chemical, physical, and optical properties as the natural diamonds. The only point of a difference these two diamonds is its point of origin. Naturally occurring diamonds, though beautiful, involve a lot of destruction of the earth's crust. Thus lab-grown diamonds are undoubtedly an economical and environmentally friendly approach to fulfilling our desire to own a hefty piece of diamond.

CVD diamonds from CVD diamond suppliers are an efficient, pocket-friendly alternative to a naturally occurring diamond. These do not include the cost of mining that goes in the extraction of natural diamond, and thus, there is a noticeable difference in the price as well.

CVD diamonds have just started gaining popularity and judging by its growth; it will surely be a billion dollar market someday along the line. Its demand is increasing as people are becoming more aware of their pocket extent and making eco-friendly choices as well.
