What “Lab Grown Diamonds” Really Means
Lab grown diamonds are real diamonds with the same physical, chemical and optical properties as diamonds formed underground. The only difference is their origin, created in a controlled environment using advanced technology.
They are not simulants like cubic zirconia or moissanite. They are true diamonds that are graded, certified and valued the same way.
This makes them ideal for engagement rings, anniversary jewellery, gifts and heirlooms.
