What are CVD Diamonds Made Of? 4 Key Points Explained

CVD diamonds, or Chemical Vapour Deposition diamonds, are made of pure crystalline carbon.

This composition is identical to natural diamonds in both chemical and physical properties.

These diamonds are created in a laboratory setting using a process that involves heating a mixture of hydrocarbon gas and hydrogen at low pressures.

This results in the formation of diamond crystals.

Unlike cubic zirconia, which is made from synthetic zirconium dioxide and merely resembles diamonds, CVD diamonds are authentic and indistinguishable from natural diamonds without specialized equipment.

What are CVD Diamonds Made Of? 4 Key Points Explained

Composition of CVD Diamonds:

CVD diamonds are made of pure crystalline carbon, the same material as natural diamonds.

This composition ensures that CVD diamonds have the same physical and chemical properties as natural diamonds.

Production Process:

The CVD process involves introducing a mixture of hydrocarbon gas and hydrogen into a chamber at low pressures and high temperatures.

Some of the hydrogen converts to atomic hydrogen, which aids in the formation of diamond crystals.

This method mimics the conditions under which diamonds form naturally deep within the earth.

Distinction from Cubic Zirconia:

Unlike cubic zirconia, which is made from synthetic zirconium dioxide, CVD diamonds are true diamonds.

Cubic zirconia is designed to resemble diamonds but lacks their fire and brilliance.

Indistinguishability from Natural Diamonds:

CVD diamonds are indistinguishable from natural diamonds without specialized equipment.

They have the same visual and physical properties as mined diamonds.

Authentic laboratories that manufacture and grade CVD diamonds inscribe them as lab-grown diamonds.

Emergence and Popularity:

The CVD process has been around for over a decade and has gained popularity due to its ability to produce high-quality diamonds.

The technology behind CVD diamonds allows for the creation of gem-quality diamonds that are identical to natural ones.

In summary, CVD diamonds are a result of advanced laboratory technology that replicates the natural formation process of diamonds.

They are made of pure crystalline carbon and possess all the characteristics of natural diamonds, making them a viable and indistinguishable alternative in the diamond market.
