Loose diamond at auction in Australia
Diamonds are graded on the familiar four: carat, colour, clarity and cut. Unlike the coloured stones in this catalogue, that ladder means something precise for a diamond, so we use it rather than our two-word grade.
Natural and lab-grown are both real diamonds and they are labelled unmistakably apart, because they are not worth the same and never will be. A laboratory can make more; the ground cannot. Coloured diamonds, and Australian pink diamonds in particular, are a separate market again, and the closure of the Argyle mine removed the source that supplied most of the world's pink.
What to look for in diamond
- Natural or lab-grown, stated on every lot. This is the single largest determinant of value.
- Cut quality, which does more for how a diamond looks than colour or clarity grades do.
- Whether a lab report accompanies the stone, and which laboratory issued it.

Reading on diamond
Why natural still matters, when a lab can print a diamond for a fifth of the price
Lab-grown stones are real, and they have a place. But a printable thing has no scarcity, and scarcity is where a stone holds its value.
