Do lab-grown diamonds break easily?

No, Lab-grown diamonds have the same hardness as mined diamonds as they have the same atomic structure. Carbon is the main element in both mined and created diamonds.

 Cultivated diamonds are created in machines with the use of high pressure and extreme temperature, replicating nature’s way of making diamonds. The end result- diamonds that are exactly the same as mined diamonds- physically, chemically & optically. Mined diamonds have a crystal structure and so do lab grown diamonds. Lab grown diamonds replicate the crystal lattice-like atomic structure of mined diamonds.
