    Diamond Certificates

    Every single diamond we handle has been thoroughly inspected and graded by the Gemological Institute of America (GIA), a world-renowned diamond laboratory. The diamond you purchase will be accompanied with its own GIA certificate, which includes an assessment of the diamond’s 4Cs – cut, clarity, colour and carat weight – along with a visual diagram of the diamond’s proportions.

    Most diamonds will also be laser inscribed with its individual certificate number so you will always be able to identify your diamond.


    Gemological Institute of America (GIA)


    The Gemological Institute of America (GIA) is one of the most respected and recognised diamond laboratories in the world, and diamonds that come with GIA certificates are the most highly valued in the world.

    All diamonds submitted to the GIA for examination are guaranteed to be graded reliably and consistently, with anywhere from three to six separate gemmologists individually reviewing each diamond for an accurate final grade.

    For more information on the GIA Laboratory diamond grading process, head over to GIA’s Lab Reports & Services.
