The Four Cs
Cut
How precisely the facets are angled — the engine of sparkle.
Very Good
Reflects most light that enters — a lively, bright stone.
Excellent
Precision angles return nearly all light as brilliance and fire.
Ideal
The rarest proportions — maximum sparkle, edge to edge.
Colour
The absence of tint — graded from D (none) downwards.
G
Near-colourless. Warmth is imperceptible once set.
F
Colourless to the trained eye. Exceptional value.
E
Colourless. Only a master gemologist detects any tint.
D
Absolutely colourless — the highest grade there is.
Clarity
How free the stone is of internal characteristics.
VS2
Inclusions invisible to the naked eye.
VS1
Minute inclusions, hard to see even at 10×.
VVS2
Very, very slight inclusions — collector grade.
VVS1
All but flawless. Among the purest stones grown.
Carat
The weight of the stone — one carat is 0.20 grams. Size follows weight, but cut decides how large a stone looks.
