The difference between cultivated and natural diamonds

Color difference

At present, the quality of cultivated diamonds can also reach colorless or coffee color, almost unrecognizable to the naked eye. Cultivated diamonds can also have many colored diamonds, among which the more common are white and yellow diamonds.

Characteristics of diamond crystal cultivated at high temperature and pressure:

HPHT synthetic diamonds are usually octahedral and cube shaped, and can develop rhombododecahedral, tetrahedral or triangular trioctahedral crystal faces. Natural diamonds are usually octahedral,

The rhombic dodecahedron and the conflation of both, and the common triangular lamellar double crystals.

CVD Cultivated diamond crystal characteristics:

Natural diamond crystals form at about the same temperature as lab-grown diamonds, but natural diamonds grow into octahedral (eight equilateral triangular crystal faces) crystals while cultured diamond crystals can contain all eight

Hedral and cube (six square crystal faces) crystal Natural and cultivated diamonds are made of pure carbon crystal, both physical properties, chemical properties, crystal structure and optical properties are exactly the same
