Why should you choose lab-grown diamonds?

Are Lab Grown, Man-made, Synthetic Diamonds Real?

“They are real diamonds. They have the same optical, chemical, thermal, and physical features.”
Matthew Hall, Director, Gemological Institute of America (GIA).

In fact, they are essentially identical to natural diamonds in every way except for their origin. Lab grown diamonds are created using advanced technological processes that mimic the conditions under which natural diamonds are formed deep within the earth.

Lab-created diamonds are graded at the same laboratory as natural diamonds such as GIA and IGI.

What is the difference between a laboratory-created diamond and a natural diamond?

A laboratory-created diamond is a man-made diamond that has the same physical, chemical and optical properties as a natural diamond. The main difference between the two is that lab diamonds are created in a controlled environment, while natural diamonds are formed over millions of years deep within the Earth’s crust.

How are Lab Grown Diamonds made?

Lab grown diamonds are made in one of two ways: high pressure, high temperature (HPHT) or chemical vapour deposition (CVD).


In the HPHT method, a small diamond seed is placed in a chamber with carbon and a metal catalyst, usually iron. The chamber is then placed under high pressure and temperature, which causes the carbon atoms to attach themselves to the seed diamond and grow it.


In the CVD method, a small diamond seed is placed in a chamber with carbon-containing gas, such as methane. A plasma arc is then used to heat the chamber until the carbon atoms break away from the gas and attach themselves to the seed diamond, growing it.

What is the Difference Between CVD and HPHT Diamonds?

So, what is the difference between CVD and HPHT diamonds? CVD diamonds are created through chemical vapour deposition, while HPHT diamonds are created through a process of high pressure, and high temperature. Both methods can create synthetic diamonds, but HPHT diamonds are more likely to be of higher quality.

Should I Get a Lab Grown Diamond Engagement Ring?

Lab grown diamonds are diamonds created in a laboratory rather than mined from the earth. Because they are created in a controlled environment, man-made diamonds can offer some benefits over natural diamonds. For example, they can be more affordable and less likely to have impurities or inclusions.

Of course, whether or not a grown diamond engagement ring is right for you is a personal decision. Some people may prefer the traditional idea of a natural diamond, while others may be more drawn to an eco-friendly and more affordable ring. Ultimately, it’s up to you to decide what type of engagement ring best suits your needs and budget.

If you’re still unsure whether a grown diamond engagement ring is right for you, we suggest talking to a jeweller who can help you weigh the pros and cons. They can also show you some beautiful lab grown diamond engagement rings to help you decide.

Frequently Asked Questions

Yes, lab diamonds have the same physical and chemical properties as natural diamonds. They are identical in every way except for their origin. Lab-grown diamonds have the same sparkle, fire, and brilliance as natural diamonds.

Yes, lab-created diamonds can be sustainable. While traditional diamonds are mined from the earth, lab-created diamonds are grown in a controlled environment. This means that the environmental impact of producing lab-created diamonds is much lower than that of traditional diamonds.

Synthetic diamonds are physically identical to mined diamonds. They are created using the same process of heat and pressure. However, mined diamonds are not sustainable. They are extracted from the earth, which can have negative environmental impacts. A Lab-grown diamond is more sustainable because they do not require mining.

Lab made diamonds can have a lower carbon footprint if they use renewable energy such as solar or wind.

In addition, lab-created diamonds can be an ethically sound alternative to mined diamonds. Since they are not mined, there is no risk of human rights abuses or conflict associated with their production.

The benefits of lab-created diamonds include being more affordable than natural diamonds, having the same sparkle and brilliance as natural diamonds, and being sustainable.

There are many reasons to choose lab-created diamonds over natural diamonds. Lab-grown diamonds are more affordable, have the same physical and chemical properties as natural diamonds, and are sustainable. Natural diamonds can be expensive, and mining can be harmful to the environment.

One concern about lab-created diamonds is that they may not have a grading certificate from the Gemological Institute of America (GIA). However, many reputable diamond retailers offer their own certificates of authenticity or gemologist appraisal reports to ensure that their customers are getting a high-quality diamond. So, if you’re considering an engineered diamond, be sure to do your research and select a reputable retailer.
