Frequently Asked Questions

What is a lab grown diamond?

As the name suggests, lab grown diamonds are man made diamonds created in a lab. They are grown in highly controlled environments using technological processes to mirror the elements of a natural diamond. As they consist of carbon atom structures, lab diamonds exhibit the same physical, chemical and optical characteristics of a natural diamond produced by mother nature.

Note: Lab made diamonds are also commonly known as the following: lab created diamonds, man made diamonds, engineered diamonds, cultured diamonds, above earth diamonds, mine-free diamonds, ethical diamonds, synthetic diamonds, artificial diamonds and manufactured diamonds.

How are lab grown diamonds made?

Man made diamonds are grown in a lab by replicating the process that results in the creation of natural diamonds. They are created from tiny pieces of pre-existing diamonds, also known as the diamond seed. From here, the seed is placed in an advanced technological chamber, designed to mimic the conditions within the Earth’s crust. During this process, the seed is coated in pure carbon which will eventually transform into a synthetic diamond. Within a matter of weeks, a lab diamond, chemically identical to a natural diamond is produced.

Can you tell the difference between a natural and lab grown diamond?

To the naked eye, a lab diamond looks identical to a natural diamond. They can be distinguished from natural diamonds using specialised equipment that can detect the minor differences in trace elements and crystal growth. All reputable jewellers should have this equipment available in-store.
