How diamonds are valued
The four Cs — and then some
Carat weight
The physical weight of the stone measured in carats (0.2g per carat). Larger stones command a significant premium per carat.
Colour grade
From D (colourless) to Z (light yellow). Colourless stones are rarest and most valuable. Fancy coloured diamonds are assessed separately.
Clarity grade
FL (flawless) to I3 (included). We use loupe and microscope examination to assess inclusions accurately.
Cut quality
A well-cut stone reflects light brilliantly and is worth more than a poorly cut stone of the same weight and colour.
Common questions
Selling diamonds — answered
Do I need a GIA certificate?
A certificate helps confirm the stone's grading and can increase the offer, but it's not required. We assess unmounted stones directly and make an offer based on our own evaluation.
How are diamonds valued?
Diamonds are assessed on the four Cs — carat weight, colour, clarity and cut — plus current wholesale market demand. We research comparable stones before making any offer.
Can I sell a diamond that's still in its setting?
Yes. We can assess the stone in its setting or have it removed by our bench jeweller. The gold or platinum mount is valued separately.
What if I have multiple stones?
We welcome collections. Each stone is assessed individually, and you receive a full itemised offer. For large collections, contact us directly before sending.
