Real Synthetic Diamonds

A true synthetic diamond is a real diamond in every sense: chemically, physically, optically and atomically. The primary difference between synthetic and natural diamonds is in their respective origin – the first one is grown in a specially created environment using sophisticated machinery while the latter grew in the Earth's mantle millions of years ago and is currently being mined. Being the same material, merely with different origins, lab-grown and natural diamonds have similar properties.

This chart compares the properties of mined and synthetic diamonds and common diamond simulants:

Diamonds produced by AOTC Group have many names: laboratory created, laboratory grown, man-made, cultured, synthetic – all of which are synonymous and legitimate descriptors. The term 'synthetic diamond' by definition is absolutely correct, however we prefer to call them 'lab-grown' or 'lab-created', since in many connotations associated with gem-quality diamonds, 'synthetic' is commonly misinterpreted and misused.

Our diamonds should not be mistaken with diamond simulants, commonly advertised illegally as 'synthetic diamonds'. Simulants, or imitations, may resemble diamonds but none of them possess the very set of properties which makes a diamond the ultimate gem in regard to its beauty and durability. Common simulants include cubic zirconia (CZ), moissanite, white sapphire and lead crystal.

AOTC proudly discloses the origin of all of its diamonds without any exclusion. Furthermore, each graded diamond is laser inscribed as "AOTC CREATED" which is reflected in the the grading report.
