In today’s jewellery world, lab grown diamonds are a compelling alternative to mined diamonds due to their identical composition to natural diamonds that offer strong value along with an ethical advantage. Many consumers want to understand the difference between CVD and HPHT lab grown diamonds before they buy, as these two methods of diamond creation make up the primary ways that lab grown diamonds are produced.
If you are considering buying rings, earrings, or necklaces, understanding the difference helps you make an informed decision. Both CVD and HPHT lab grown diamonds are real diamonds that have the same chemical composition as natural diamonds, but the way the lab grown diamonds are created is different, and some characteristics may vary, particularly in appearance and pricing.
In this guide, we will explain the differences between the two types of lab grown diamonds (CVD and HPHT) to help you decide which will best meet your needs.
CVD Vs HPHT Lab Grown Diamonds: A Summary Of The Basic Differences
To understand the difference between a CVD and HPHT lab created diamond, it is important to know about the methods of production for each type.
Chemical vapour deposition (CVD) is a process used to make lab created diamonds. It uses carbon-containing gases to form the diamond's crystal structure layer by layer in a vacuum chamber.
CVD diamonds are often associated with strong clarity, and are produced in every type of jewellery.
HPHT diamonds are created by compressing carbon with high temperature and high pressure to replicate natural diamond-forming conditions. The process used to create the diamond's crystal structure in this manner closely resembles natural diamond formation.
Understanding how these diamonds are created is important for making an informed choice for the type of lab grown diamond you choose that is consistent with your preferences, budget, and personal style. A common question is - which is the best lab grown diamond method, CVD or HPHT? The answer to that question depends on what you value the most.
Generally, the CVD diamonds tend to produce larger stones, offering strong clarity. Many premium lab grown diamond engagement rings contain CVD diamonds due to their beauty and are widely used in the market.
HPHT diamonds are produced with a strong colour consistency, and in most cases, produce incredible quality diamonds. Many HPHT diamonds are often used to enhance the diamond's colour grade.
Choosing the best method is important to most buyers, but if larger size and clearer stone character are most important to you, CVD would likely interest you more than HPHT due to its appeal. If naturally replicated growth conditions are of interest to you, then HPHT stones would be your choice.
Comparing Pricing And Value: CVD Vs HPHT Diamonds
Additionally, when comparing CVD vs HPHT diamonds, features other than diamond characteristics and certifications should include pricing. Both types of diamonds will be less expensive than mined diamonds, but may vary in price, depending upon their size, cut, colour, and certifications.
CVD diamonds are more widely available than their HPHT counterparts; therefore, more competitive pricing can be expected from CVD diamonds. However, HPHT diamonds pricing may ideally be somewhat higher than CVD as a result of their individual characteristics and methods of production.
Consumers seeking beautiful day-to-day wearable diamond jewellery will receive strong value from both processes. The smart CVD vs HPHT diamond comparison should remain focused on the actual stone rather than just the growth process.
The following key points illustrate the CVD and HPHT diamond differences to make your buying experience easier.
Differences Between CVD And HPHT Diamonds
-
Growth Process: CVD diamonds are created using a method known as the gas-based deposition process; HPHT diamonds are formed by means of heat and pressure.
-
Appearance: Both CVD diamonds and HPHT diamonds will appear identical.
-
Availability: CVD diamonds are available in the majority of jewellery categories.
-
Technology: Although HPHT diamonds are very close to mimicking the natural processes found on earth to create diamonds, CVD diamonds are still widely used across jewellery categories, because there are a variety of types of CVD diamonds available.
Both methods produce diamonds with similar properties; however, there are still some important differences between CVD and HPHT diamonds that will assist you when it comes to choosing between the two types of diamonds to purchase for your jewellery.
There are many wonderful jewellery collections containing both CVD diamonds and HPHT diamonds.
Best Lab Grown Diamond Method: CVD Or HPHT For Jewellery Buyers
When deciding between CVD and HPHT diamonds, are the best for your jewellery, consider what is most important to you:
-
Wide availability and clarity range: CVD
-
Preference for diamonds formed from heat and pressure: HPHT
-
Best price: depends on the individual stone
-
Prioritising cut over process: depends on preference
At the end of the day, the lab created diamond you decide to purchase depends on the quality of the diamond and not just how it was made. Experts usually suggest starting with certification, cut, and sparkle before you weigh the pros and cons of the manufacturing process.
How To Choose A Lab Grown Diamond
Instead of choosing based solely on the manufacturing process, focus on these factors to determine the lab created diamond that meets your needs:
-
Cut grade
-
Color grade
-
Clarity grade
-
Weight (carat)
-
Certification
-
Seller reputation
Diamond quality depends on cut. When comparing diamonds that have been made from both lab created diamonds, the quality of the diamond is the key factor.
FAQs
1) How are CVD lab created diamonds Vs HPHT lab created diamonds different from each other in their creation?
CVD diamonds are created using gas to turn carbon into diamonds; HPHT diamonds are created under heat and pressure.
2) Which is the best lab grown method between CVD and HPHT?
There is no single answer to determine which is better; that will depend on what you want in the diamond.
3) Why is it important to consider CVD vs HPHT lab created diamonds when purchasing?
In general, by looking at both diamond creation processes, you will have a better understanding of how diamonds are formed.
4) Are there any distinguishable differences between CVD diamonds and HPHT diamonds when viewed through the naked eye?
No, as a result of having the same composition as mined diamonds, both CVD diamonds and HPHT diamonds will appear identical to one another. The certification provides the assurance of an actual CVD or HPHT diamond.
5) Which method produces the best lab grown diamonds for engagement rings?
Both CVD diamonds and HPHT diamonds will produce a wonderful quality diamond that will last a lifetime. The final choice will be dependent on the price, cut, and brilliance of the diamond.
6) Are diamonds created from CVD and HPHT processes real diamonds?
Yes, diamonds from both processes have the same chemical properties as diamonds that are mined from the earth.
The CVD vs HPHT lab grown diamond comparison is often made to sound more confusing than it actually is; there are both CVD diamonds and HPHT diamonds, and both types of diamonds can make a stunning addition to today's modern wedding day jewellery collection.
When it comes to comparing CVD vs HPHT lab grown diamonds, the key is to look beyond the manufacturing process in determining the quality and size of your diamond; the focus should be placed on the cut, certification, and overall appearance. Additionally, when purchasing a diamond for your special day, remember to choose the method of diamond production that best fits both your style and budget.
