Diamond buying guidance
Compare natural diamonds with the right data
Use the live stone record to compare size, grading and finish consistently before choosing a diamond.
Colour & clarity
Grades are useful comparison points, but they should be reviewed together with the supplied imagery, video and report information.
Cut & finish
Where supplied, compare cut or proportions together with polish and symmetry rather than relying on a single grade in isolation.
Grading report
Check the grading laboratory, report number and certificate information shown for the individual stone where these are supplied.
A more useful shortlist
Build a shortlist before choosing
Compare two to four live stones using the same criteria. Price differences can reflect a combination of characteristics and supplier availability. The individual live-stone record remains the source of truth for current price, availability and the grading information supplied.
Before you choose
Is every diamond independently graded?
Only rely on grading-laboratory and report details when they are supplied on the individual live-stone record. That record is the source of truth for the information available for a particular stone.
Can I compare two stones before choosing?
Yes. Send the links or report numbers to our team and we can help you compare the product information shown for each stone.
Can I use a selected diamond in an engagement ring?
Yes, subject to the stone's current availability and compatibility with the chosen setting. We can discuss the setting or bespoke route with you before an order is finalised.
