Choosing a diamond comes down to four things jewellers call the 4Cs. Here's what each one means, in plain terms.

Carat

Carat measures a diamond's weight, not its size — two diamonds of the same carat weight can look different sizes depending on how they're cut. 1 carat equals 0.2 grams.

Cut

Cut is about how well a diamond's facets interact with light — it's the single biggest factor in how much a diamond sparkles. A well-cut diamond of a smaller carat weight can outshine a larger, poorly cut one.

Colour

Diamonds are graded from D (colourless) to Z (noticeably yellow or brown). Most people can't tell the difference between a D and an H in a mounted ring, so this is often a good place to save without sacrificing beauty.

Clarity

Clarity refers to internal marks (inclusions) or surface marks (blemishes). Most inclusions are invisible to the naked eye — you're really only paying for what a jeweller's loupe can see.
