The 4Cs

Carat, cut, colour, clarity

Four things decide how a diamond looks and what it costs. Here's what matters, and where you can save.

Carat

Weight, not size. A 2 ct stone is only about 25% wider than a 1 ct stone, but costs much more.

1.00 ct

Cut

The one C to never compromise on. A well-cut diamond sends light back out of the top; a shallow or deep one leaks it out of the sides.

  • Too shallow
  • Ideal
  • Too deep

Colour

D is icy white; K has a hint of warmth. In white gold, G and H look colourless to most eyes, for less.

  • D
  • E
  • F
  • G
  • H
  • I
  • J
  • K

Clarity

Tiny natural marks inside the stone. VS1 and VS2 are "eye-clean": you'd need a loupe to find anything.

  • VVS
  • VS1
  • VS2
  • SI
