What affects the value of a diamond?
Every diamond is different. A professional review considers several details rather than size alone.
Carat
Carat is the weight of a diamond. A heavier diamond is not automatically more valuable because its other qualities also matter.
Cut
The cut affects how the diamond reflects light and appears to the eye. Shape and cut quality are considered separately.
Colour
The visible colour of the stone can affect its quality and potential market value.
Clarity
Clarity considers natural internal features and surface marks, including their size, position and visibility.
This information is a simple guide, not a laboratory grade. Final eligibility and any offer require an in-person assessment.
Other details we may consider
The 4Cs are important, but they are not the only details relevant to a diamond buying assessment.
- Natural, laboratory-grown or treated status
- Diamond shape, measurements and condition
- Jewellery setting and precious-metal content
- Grading report and supporting documents
- Current buyer demand and market conditions
