Diamond Education

Understand your diamond.

What our D colour, VS1 clarity standard means, and how carat weight, size and shape relate — explained briefly.

Colour

Our collection: D

Colour is graded on a letter scale beginning at D. D, E and F sit in the colourless range, with D at the top of the scale. Colour describes the stone only; it says nothing about how it is cut.

Clarity

Our collection: VS1

Clarity describes internal and surface characteristics as seen by a trained grader at 10x magnification. VS1 and VS2 are “Very Slightly Included”: minor inclusions that are noticeable under magnification.

Carat

Weight, not size

Carat measures weight. How large a stone looks also depends on its shape, proportions and measurements, so two stones of equal weight can face up differently. For earrings, tell us whether you mean weight per stone or for the pair.

Shape vs cut

Two different things

Shape is the outline — round, oval, emerald, pear, heart or marquise. Cut quality is a separate assessment of proportions and finish. Naming a shape does not state a cut grade.

Common Questions

Frequently asked.

What diamond specification does the collection use?
Our collection diamonds are D colour, VS1 clarity. All sizes available to enquire about — tell us the carat weight and size or length you have in mind and we will confirm options for your chosen piece.
Does every piece come with a grading report?
Not necessarily. A grading report describes one specific stone or piece of jewellery. Ask us for report details on the piece you choose; we only describe a stone as reported when a report for that stone supports it.
Are your diamonds natural or lab-grown, and which metals are used?
Ask us for the origin, metal and any report details for the specific piece you are considering, and we will confirm them in writing for that piece.
How long will my piece take?
Ask us about timing for your chosen piece and destination.
Is “D” a cut grade?
No. D is a colour grade. Shape and cut quality are separate from colour.
