HPHT VS CVD Diamonds: Which Diamond Is Better For You?

Diamond is the most beloved and desired gemstone that everyone seeks to purchase. As the world moves towards a sustainable and ethical environment, lab grown diamonds have become the talk of town! A safer way to form a diamond that possesses the same characteristics as natural ones. However, just because they are formed in a laboratory doesn’t mean they’re all created using the same methods. They are created in two different methods- HPHT & CVD. But the question arises which one is better among both the methods? – The argument on the superiority of HPHT Vs CVD Diamonds adds a layer of complexity to this discussion. But to clear out this confusion You need to first understand-’ what’s the difference between CVD and HPHT diamonds?’ While both types are created in a controlled laboratory environment their distinction lies in the processes employed. Not just this but many other points make them different. To get a clear picture, read the article further and make a clear decision on which is better HPHT or CVD Diamonds for your next purchase.  

For a reliable source of lab grown diamonds, consider exploring the offerings at Bhanderi, a trusted lab grown diamonds manufacturer USA in the market with years of experience. Choose sustainability without compromising on quality with the leading brand.

Get An In-Depth Exploration: Difference Between HPHT Vs CVD Diamonds 

Lab grown diamonds are made in two different methods: HPHT & CVD. While both these methods generate sustainable diamonds, their formation processes & characteristics diverge them significantly. So, learn the differences between HPHT Vs CVD Diamonds and make a decision about which is best for you.  

Color Distribution-

• CVD diamonds typically boast a more uniform color distribution, often achieving higher levels of clarity and color. This is due to they are colorless.  
• In the past, HPHT diamonds tended to develop a yellowish tint due to nitrogen presence, but advancements in techniques have addressed this over the years.  

Formation Process- 

• CVD diamonds are grown by placing a diamond seed in a vacuum chamber and then filling the chamber with a mixture of carbon-rich gases. The gases are heated to a high temperature, which causes them to break down into individual carbon atoms. The carbon atoms then bond to the diamond seed, forming a new layer of diamond.
• HPHT lab grown diamonds are formed by placing a diamond seed in a press and then subjecting it to high pressure and high temperature. The pressure and temperature cause the carbon atoms in the seed to rearrange themselves into a diamond lattice.

Crystal structure- 

• CVD diamonds grow in a cubic shape with a single growth direction. This can sometimes cause strain in the diamond, which may be visible under high magnification.
• HPHT diamonds take shape in a cuboctahedron form, growing in 14 different directions. This makes them less likely to have strain.

Understanding the above given difference can help you in making an informed decision when considering between HPHT Vs CVD Diamonds. 

HPHT VS CVD Diamonds: Which One Is Best? 

Now that we have learned the difference between both the methods of lab grown diamonds. It is time to answer the question- Which one truly shines better? 

To answer this question- The choice between CVD Vs HPHT Diamonds is not a one-size-fits-all decision, as each method has its unique advantages and considerations. Whether it’s the controlled brilliance of a CVD gem or the natural allure of an HPHT stone, both options offer stunning choices. 

HPHT diamonds replicate the natural gems formation process by subjecting carbon to high pressure and high temperature. On the other hand, CVD diamonds USA grow from carbon-rich gases in a controlled chamber, offering efficiency & scalability. 

Lastly, the decision ultimately boils down to the personal preference that you desire in your diamonds. But make sure to not compromise with quality & beauty. When you choose Bhanderi lab grown diamonds you don’t have to look for more. As a completely shining brand, you can get to choose those sparkling diamonds that are certified by well-known international labs. 

FAQs

• Which is the better form of diamond, CVD or HPHT? 

The most confusing yet unsolved question. To answer this question- choosing from among both the methods HPHT vs CVD diamonds depends on various factors & personal preferences. Both the methods are unique in their way. Below are the points you should consider while making a decision. 

• Preferences: Your preference for color distribution, fluorescence, and growth patterns may influence your choice.
• Purpose: Consider the purpose of the diamond, whether it’s for a specific piece of jewelry or investment.
• Budget: Evaluate your budget, as prices may vary between CVD and HPHT diamonds.

Lastly, it’s recommended to assess the specific characteristics of each type and choose based on what aligns with your preferences and values.

• Do HPHT and CVD diamonds cost differently? 

Yes, diamonds produced from both methods cost differently. While both CVD and HPHT diamonds are more affordable than natural diamonds, CVD diamonds are more economical. 

• How do CVD diamonds benefit the user?

CVD diamonds offer several benefits, including cost-effectiveness, as they are typically more budget-friendly than natural diamonds. Their production process allows for the creation of diamonds with an even color distribution, higher clarity, and fewer instances of fluorescence. Additionally, CVD diamonds are known for their efficiency and scalability, making them a sustainable and accessible option for those seeking environmentally conscious and affordable alternatives to natural diamonds.
