Carat size on the finger
Drawn to scale on a size 6 finger (16.5 mm wide). Sizes are approximate face-up measurements.
Carat is weight, not size. A 2.00 ct stone looks about 25–30% wider than a 1.00 ct, not twice as wide. On a slimmer finger the same stone looks bigger.
Diamond colour & clarity
Colour runs from D, with no colour at all, towards a faint yellow. D–F look icy white. G–H look white once set, especially in yellow or rose gold.
Clarity is how many tiny natural marks a diamond has. From VS1 upwards they can't be seen without 10× magnification.
| Grade | What it means |
|---|---|
| FL · IF | Flawless — nothing seen at 10× |
| VVS1 · VVS2 | Very, very slight — very hard to find at 10× |
| VS1 · VS2 | Very slight — eye-clean, minor marks at 10× |
| SI1 · SI2 | Slight — usually eye-clean in smaller stones |
| I1 | Included — marks may be visible to the eye |
