When comparing Chemical Vapor Deposition (CVD) diamonds to High Pressure High Temperature (HPHT) diamonds, the answer isn't straightforward.
It depends on various factors, including the intended use and specific quality requirements.
7 Key Points to Consider
1. Aesthetic Quality and Production Efficiency
HPHT diamonds are generally known for their superior aesthetic quality.
They often have fewer undesirable traits like brown undertones, spotty inclusions, and internal graining.
However, the production process for HPHT diamonds is more energy-intensive and costly.
CVD diamonds, on the other hand, are produced more quickly, less expensively, and with less energy.
But they may require post-growth treatments to improve their appearance, which can sometimes result in a milky or hazy appearance.
2. Chemical Purity and Versatility
CVD diamonds are chemically pure and do not require the use of gases like nitrogen and boron, which can infiltrate HPHT diamonds.
This purity makes CVD diamonds suitable for various applications beyond gemstones, including in optics, computer sciences, and tool production.
CVD also allows for diamond deposition on substrates other than diamond, enhancing its versatility.
3. Size and Clarity
Both methods can yield high-grade diamonds, but CVD diamonds often have higher clarity (mostly VVS-VS) and are free of metallic inclusions.
However, CVD currently faces limitations in producing diamonds over 3.2 carats, which is a significant factor in the jewelry industry.
4. Distinguishing Between HPHT and CVD Diamonds
Once faceted, it is almost impossible to distinguish between HPHT and CVD diamonds by appearance alone.
Both methods can produce high-quality diamonds with D to F colors and clarity grades ranging from VS2 to VVS1.
5. Conclusion
The choice between CVD and HPHT diamonds depends largely on the specific needs and priorities of the user.
For those prioritizing aesthetic quality and willing to invest more in production, HPHT diamonds might be preferable.
Conversely, for applications requiring chemical purity, versatility, and lower production costs, CVD diamonds are often the better choice.
