More Info

With their growing popularity, are you left wondering: what are lab grown diamonds? These diamonds are man-made but look just like real, naturally formed diamonds. They share the same chemical and optical qualities as real diamonds, containing carbon atoms. A striking similarity is bared, even though lab diamonds are manufactured synthetically and real diamonds are formed through natural, earthly processes. Here, we'll give you all you need to know about what lab grown diamonds are and where you can buy them.

What are Lab Grown Diamonds and How are They Made?

To make lab grown diamonds, the exact same processes are followed that allow real diamonds to form. Real diamonds grow as a result of millions of years of heat and pressure that changes carbon atom structures into beautiful, naturally carved diamonds. With lab grown diamonds, man-made methods allow the same results to occur within a matter of weeks, producing diamond structures that resemble the real thing. 

Starting with what's known as a diamond seed, this small diamond segment is added within a system that performs processes similar to those provided by the earth for natural diamond creation. The seed develops into artificial diamonds with chemical structures that are just like those found in real ones.

Lab grown diamonds can be made by using one of two different processes: These are:

  • Chemical Vaporization High-Pressure High Temperature (CVD)
  • High pressure-High Temperature (HPHT)

With HPHT, a strong heat of around 1,500 degrees Celsius (2,700 degrees Fahrenheit) and 1.5 million pounds of square inch per pressure is placed on the seed diamond. Lower levels of heat and pressure are needed for CVD. Chemicals are added with CVD that allows diamond structures to be created when mixed together. While the two methods differ in relation to heat, pressure, and ingredients, they both produce man-made diamonds grown in a lab in a very short time.

Differences Between Lab Grown and Natural Diamonds

There are several other ways in which the two types of diamonds differ in addition to the chemical process that's involved. These include the market value, as well as some structural qualities of both diamonds. Let's take a look at them.


Natural diamonds are much more expensive than lab grown diamonds. That's because real diamonds are rare and it's believed that there is becoming less stone available over time that can give rise to the natural processes involved in diamond creation. Also considered in the price are the costs involved in:

  • Labor
  • Energy
  • Mining
  • Maintenance
  • Marketing

Lab grown diamonds can be up to 50% less expensive than real diamonds. That way, you get to benefit from a diamond that looks the same at better affordability. At Rare Carat, we offer top-quality diamonds at a lower price.

Strength and Durability

While natural diamonds are a bit more durable than man-made ones, lab diamonds are still very strong and difficult to chip. So you can still receive the benefits of high durability when purchasing man-made diamonds.


Lab grown diamonds are graded on how the stone sparkles. Higher-graded man-made diamonds have more inclusions and are clearer. They are graded on a scale where they are labeled somewhere between Flawless (F1) and Included (I3), depending on how clear they are. Therefore, it will be best to keep in mind that only the best lab grown diamonds will be graded at the top level when matched in clarity to real diamonds. Seek out a lab diamond supplier that only sells the best quality of diamonds. You can check out our range of clear and pristine diamonds on our website.


Just as with clarity, a similar grading is followed for color. Highly graded lab grown diamonds for color will look the same as natural diamonds. No real difference can be seen here. The grading system for color ranges from D to F. Those that are entirely colorless are hard to find, and therefore are much more expensive.
