Lab grown Diamond

A laboratory grown diamond is man-made but features the same optical and physical properties as a natural diamond, including its chemical composition, refractive index and 4Cs. The only difference is its point of origin: one is grown above ground, while the other is extracted from the ground. Laboratory grown diamonds can be produced by two methods. One is HPHT, under high pressure and high temperature; the other is CVD, chemical vapour deposition.

Their advantage over natural diamonds? Maybe the fact that they are more environment-friendly than their natural counterparts (no mining process), but the difference in price should mainly tip the scale! Indeed, lab grown diamonds are sold about 30% cheaper than natural diamonds…
