Lab grown diamonds are 40-50% less to buy than their identical mined ancestors.

Are lab grown diamonds real?

Yes, lab grown diamonds are identical to mined diamonds. They are chemically, optically and physically identical. They also receive certification from the International Gemological Institute, they state “GIA Laboratory-Grown Diamond Reports and identification reports no longer use the term “synthetic.” The GIA Laboratory-Grown Diamond Report includes the standard GIA color, clarity and cut grading scales for reference purposes.”

How expensive are lab grown diamonds?

Similar to natural diamonds the price of lab grown diamonds fluctuates greatly dependant on the cut, colour, clarity and carat. However, on average a lab grown diamond is typically 40 – 50% less to buy than their identical mined equivalent.

Are lab grown diamonds ethical?

The process of creating lab grown diamonds uses up to 50% less energy compared to mined diamonds.  They are created in a controlled environment and are guaranteed conflict free, an issue that has tarnished the reputation of mined diamonds in the past.

How are lab grown diamonds made?

There are two methods used to create lab grown diamonds. The first is HPHT (high pressure high temperature) it is the original method used to create lab grown diamonds. This method replicates the natural diamond formation process by subjecting carbon to extreme temperatures and pressures. The second method CVD (chemical vapor deposition) is a newer approach that uses lower temperature and pressures than HPHT. It works by subjecting a hydrocarbon gas mixture to moderate pressures and temperatures in a vacuum chamber.
