Absolutely! Chemically, physically, and optically, lab grown diamonds are identical to natural ones. They're real diamonds with the same crystal structure and beautiful sparkle as natural diamonds. Lab grown diamonds also have the same famous Mohs hardness of 10. They're just as durable as natural diamonds and indistinguishable without their inscriptions. Lab grown diamonds have the same thermal and electrical conductivity as mined diamonds and they will pass a diamond tester exam.
Note that lab diamonds are different from other types of non-diamond stones such as cubic zirconia, moissanite and diamond stimulants. They are not made of the same structure and will generally tarnish significantly with daily wear.
