CVD Diamond

Purchase CVD Diamonds | Leading CVD Diamond Manufacturers in India

CVD diamonds, or Chemical Vapor Deposition diamonds, are a type of lab-grown diamond created in a controlled environment designed to meet specific conditions. This advanced process enables the production of stunning synthetic diamonds that mirror the brilliance and durability of natural diamonds. In India, Dhaduk Lab Grown Diamonds is renowned for its craftsmanship and expertise in producing high-quality CVD diamonds, which are exported worldwide. Over the years, India has emerged as a global hub for lab-grown diamonds, offering a diverse range of these exceptional artificial gems.

What Makes CVD Diamonds Unique and Special?

CVD diamonds are celebrated for their outstanding material properties, setting them apart from other synthetic diamonds like HPHT diamonds. These versatile gems find applications across diverse industries, including high-power electronics, radiation detection, water treatment, consumer electronics, medical diagnostics, and more. The unique characteristics of CVD diamonds make them ideal not only for fashion and jewelry but also for critical fields requiring advanced research and innovation. Dhaduk Lab Grown Diamonds is at the forefront of providing these exceptional diamonds for a wide range of purposes.

Are CVD Diamonds Real?

CVD diamonds are real diamonds with the same physical, chemical, and optical properties as natural ones. Made in weeks under precise conditions, they often surpass natural diamonds in quality. Indistinguishable from natural diamonds, they’re increasingly used in jewelry and industries. Dhaduk Lab Grown Diamonds delivers exceptional CVD diamonds with unmatched precision and sustainability.

Why are these diamonds said to be the purest among the lot?

CVD diamonds are classified as Type IIa, a category found very rarely in nature. When created in a lab, these diamonds are completely guilt-free and possess exceptional clarity. Free from boron or nitrogen impurities, they are the most chemically pure among all diamonds, giving them an edge over HPHT diamonds. However, both CVD and HPHT diamonds share the same chemical and optical properties.

What is the history of CVD Diamonds?

Among the synthetic diamonds, this type came second. While HPHT diamonds took birth in the 1940s, CVD diamonds were not developed until the 1980s. Following the invention of HPHT diamonds and how fastly they began to get value in the diamond market, researchers began to search for new methods of making synthetic diamonds. As years went by, experiments were done and the new technique was found to be effective. These methods needed lower temperatures than the previous method yet could produce identical stones to HPHT diamonds. The CVD method was thus proven to be the next best alternative to HPHT.

Are all lab-grown diamonds CVD diamonds?

No, not all lab-grown diamonds are CVD diamonds. The main types are HPHT and CVD diamonds, created using different processes, with varying purity levels. While lab-grown diamonds are chemically identical to natural diamonds, they are typically more affordable. Dhaduk Lab Grown Diamonds specializes in high-quality CVD diamonds, offering a sustainable, cost-effective alternative.

Do these come with a guarantee?

Yes, these synthetic diamonds come with the certifications of reputed institutions such as GIA, For grading, the CVD diamonds are handed over to the experts and they decide the quality of diamonds whether natural or artificial. It was in the year 2006 that GIA announced that man-made diamonds would be provided certifications by them. The Gemological Institute of America is one of the most coveted diamond grading institutes in the world. It is considered as the pioneer in the field with years of experience determining standards for grading diamonds. Like GIA there are other organizations that decide and grade CVD diamonds based on their quality. Some of them are:

The possibilities are endless! With advancements in technology and continuous improvements in grading systems, more institutes are expected to emerge, driving growth in the diamond manufacturing industry. Among these, CVD diamonds stand out as the purest, offering exceptional grades for clarity and cut. These diamonds are meticulously evaluated based on four key factors: color, clarity, cut, and carat weight.

What to look for when I buy a CVD diamond?

Chemical Deposition Vapour diamonds come in a wide variety of colors. Fancy brown, pale pink, yellow, white are just a few among the variations. They are colorless or near-colorless CVD diamonds that are in great demand. As they are replicated using machines, they can be made easily according to the demand.


The clarity of these diamonds is influenced by the controlled environment in which they are created. Inclusions may be present, affecting the clarity and texture. While some inclusions are visible to the naked eye, others remain undetectable even under magnification. High temperatures play a key role in determining the presence of these inclusions and ultimately influence the diamond’s clarity.

The most important factor, the cut, is the proportion and symmetry of the diamonds. Each CVD diamond is made more beautiful mainly by its cut than any other factor. Cuts come in various names and types. It gives the diamond its identity. The emerald cut is one of the famous diamond cuts. It is mostly used for adorning engagement rings.

The weight of a diamond varies depending on its substance and size. Like any other type, the price of a CVD diamond is primarily determined by its carat weight, with 1 carat equaling 0.2 grams. Cutting a diamond is a meticulous process that shapes the stone to enhance its appearance.

How is CVD diamond price determined?

The price of a diamond is primarily determined by the 4Cs: color, clarity, cut, and carat weight. Another crucial factor influencing diamond pricing is RapNet, the global benchmark used by dealers to set diamond prices in the market. RapNet, the largest online marketplace for diamonds, publishes a price list that reflects economic changes.

Founded in 1976, the Rapaport Group introduced its first price list in 1978. This innovation brought standardization and transparency to diamond pricing, helping the industry establish consistent pricing practices. Today, all diamond manufacturers in India rely on RapNet to determine the final price of each diamond, including dhaduklabgrowndiamonds.

From where do you have to buy your CVD Diamonds?

Certification is essential, offering you peace of mind regarding the quality and ethical sourcing of your diamond. When a company provides certification, you gain confidence that the product is worth its price. Online platforms are the best choice for purchasing diamonds and diamond jewelry, as they allow manufacturers to sell directly to customers, eliminating the need for middlemen and additional markups. At DhadukLabGrownDiamonds, we ensure you get the finest diamonds at the best value.
