What is CVD Diamond? Distinguishing CVD Diamonds and Natural Diamonds

CVD diamonds are lab-created diamonds produced in a laboratory. They are born to meet the increasing demand for diamonds while natural diamond sources are depleting and impacting the environment. Let Jemmia guide you through what CVD diamonds are, and compare them with natural diamonds in the article below. 

What are CVD diamonds?

CVD diamonds are synthetic diamonds created through a process called Chemical Vapor Deposition. This is one of the two main methods for producing synthetic diamonds. CVD diamonds are created in a laboratory environment without negatively impacting the environment or people like traditional mining. 

How are CVD diamonds made?

CVD diamonds are created by placing a small diamond seed inside a vacuum chamber. In this chamber, carbon-rich gases are activated to convert into a plasma state. Under the influence of kinetic reactions, carbon atoms from the plasma gradually deposit and crystallize vertically on the surface of the diamond seed. This process creates a rough diamond that grows in a square shape with high clarity.

It takes about a month for a rough CVD diamond to be completed. After formation, a small slice from this diamond is cut and used as a new seed, continuing the production process sustainably.

Characteristics of CVD diamonds compared to natural diamonds 

CVD diamonds, like all lab-grown diamonds, are real diamonds. They have identical properties to naturally mined diamonds, with the only difference being their origin of formation.

Similar to mined diamonds, CVD diamonds also have a variety of colors and clarity grades, and are evaluated according to the diamond industry's 4C standards.

What is the price of CVD diamonds?

According to reports from leading global diamond organizations, the global diamond industry has recorded over 20% growth in recent years and is projected to continue developing strongly in the future. In this context, synthetic diamonds are increasingly seen as an optimal choice, not only helping to minimize negative environmental impacts but also contributing to promoting ethical values in consumption.

Not only environmentally friendly, synthetic diamonds, especially CVD diamonds, possess a sparkle equivalent to natural diamonds. In terms of hardness, they are only slightly inferior to natural diamonds, but this does not affect their durability or perfect appearance.

In terms of price, CVD synthetic diamonds currently have a significantly competitive price compared to mined diamonds. In the market, natural diamonds range from 800 million VND for high-quality and high-clarity stones. Meanwhile, CVD diamonds cost only about 70 million VND per carat, meaning they are much cheaper but still ensure superior quality and aesthetics. This makes CVD synthetic diamonds a suitable choice for those who want to save their budget.

However, CVD diamonds are not the optimal choice if you are a connoisseur of diamond jewelry who wishes to accumulate and preserve lasting value over time. If you want to buy officially imported GIA certified loose diamonds, please visit Jemmia.vn immediately. 

How to care for CVD diamond jewelry

To keep CVD diamonds bright and durable, proper care is essential. Refer to the following ways to care for CVD diamond jewelry:

• Store diamonds in a sealed, dry box, avoiding contact with strong chemicals and humid environments.

• Remove diamond jewelry when doing heavy work, gardening, or engaging in strenuous activities.

• Do not wear jewelry when washing dishes, bathing, or working with water.

In addition, you should clean your CVD diamond jewelry as follows: 

• Soak the diamonds in warm soapy water for about 30 minutes, dry with a soft cloth, then store in the box.

• Periodically check and clean diamonds by professional jewelers.

• If there are large chips, take the diamonds to a reputable facility for inspection and repair.
