Lab-grown diamonds are real diamonds!

 

The biggest difference between laboratory-grown diamonds and natural diamonds lies in the difference in growth environment and formation time. Natural diamonds are naturally formed in the earth's mantle under extremely high temperatures and pressures; while laboratory-grown diamonds create a growth environment similar to natural diamonds and use several weeks to grow the diamonds.

 

Although the two have different growth environments and required times, natural diamonds and cultivated diamonds are completely consistent in terms of chemical composition, crystal structure, optical and physical properties.
