Learn Growing methods
Two paths to the same diamond.
CVD and HPHT are the two ways a laboratory grows diamond. Different physics — a plasma or a press — and an identical destination: carbon in a cubic crystal. A diamond, by every measure a gemologist has.
One grew in plasma, one in a press. No eye — trained or otherwise — can tell.

CVD — Chemical vapor deposition
A wafer-thin diamond seed sits in a vacuum chamber filled with carbon-rich gas. Microwaves ignite the gas into a plasma, and freed carbon atoms settle onto the seed one atomic layer at a time. A one-carat rough takes roughly three to four weeks.
The verdict
Both are diamonds. Full stop.
Same carbon, same crystal, same fire — certified by the same independent labs, to the same standards as mined stones. Auvi Jewels grows primarily CVD, chosen for its type IIa purity, and cuts every stone to ideal proportions.
