The art of the diamond.
Understand what makes a diamond exceptional — and how natural and lab-grown stones meet, and often exceed, traditional benchmarks.
The Four Cs
Cut
The precision of facets determines how light dances inside the stone — the only C entirely controlled by human craftsmanship.
Colour
Graded D (colourless) through Z. Aurevion stocks D through M — the most desirable colour grades.
Clarity
From Flawless (FL) to I2 — measured under 10× magnification. Every Aurevion stone is mapped and disclosed.
Carat
Weight, not size. Aurevion supplies 0.005ct melee through 10ct+ certified solitaires.
D through M — colourless to faint.
Aurevion stocks the most desirable end of the spectrum. The whiter the stone, the rarer the brilliance.
Flawless to I2.
Every inclusion is mapped under 10× magnification and reported on each certificate — full transparency, every time.
