Lab Grown Diamonds vs Mined Diamonds: Everything you Need to Know

Lab Grown Diamonds vs Mined Diamonds: Everything you Need to Know

What are Lab Grown Diamonds?

Lab grown diamonds are diamonds that are created in a laboratory setting rather than being mined from the Earth. These diamonds have the same chemical composition, crystal structure, and physical properties as natural diamonds.

How are Lab Grown Diamonds Made?

Lab-grown diamonds are made through two primary techniques. As mentioned, these are high pressure high temperature (HPHT) and chemical vapor deposition (CVD). In the HPHT method, carbon, along with a metal catalyst, is subjected to extreme pressure and temperature, replicating Earth's mantle conditions. A small seed diamond initiates crystal growth. The CVD method involves a vacuum chamber where a hydrocarbon gas, like methane, is introduced. Carbon atoms are extracted from the gas and deposited layer by layer onto a substrate, typically a thin diamond slice. Both methods yield diamonds with identical properties to natural ones.

Do Lab Grown Diamonds Have Value?

Yes, lab grown diamonds do have value, which is influenced by various factors, including the carat weight, cut, colour, and clarity. But, are lab grown diamonds cheaper? They’re often priced at a lower point than mined diamonds, making them a great option for those looking for a more budget-friendly choice. However, their value also depends on market demand, brand reputation, and the overall quality of the diamond.

Are Mined Diamonds More Valuable?

Generally, mined diamonds are often perceived as more valuable than lab-grown diamonds, but this perception is evolving, and the value of a diamond can be subjective and depend on various factors.
Traditionally, mined diamonds have been highly valued due to their rarity and the geological processes that create them over millions of years. However, as technology has advanced, lab-grown diamonds have become more prevalent. Lab-grown diamonds are typically less expensive to produce, meaning their prices are often lower.
Ultimately, the value of a diamond, whether natural or lab-grown, is influenced by factors such as the Four Cs (carat weight, cut, colour, and clarity), market demand, brand reputation, and individual preferences.

Is a Lab Grown Diamond a Real Diamond?

The question so many people ask – are lab grown diamonds real? Of course they are! Lab grown diamonds are real diamonds that have the same chemical composition, crystal structure, and physical properties as natural diamonds. So, let’s say goodbye to the lab grown diamond vs real diamond debate, as yes, they are just as real as a mined diamond.

Can a Jeweller Tell if a Diamond is Lab Created?

In many cases, jewellers can’t tell if a diamond is lab grown with the naked eye. However, there are certain advanced techniques and instruments that gemmologists and jewellers can use to identify whether a diamond is natural or lab grown.
