Diamond certifications

Diamond certifications for diamond jewellery & diamond rings in Brisbane

Your diamond certification is usually performed by an independent Gemological laboratory, which analyses the diamond for a key set of factors that determine the overall precision of make and quality of the diamond. These factors are sometimes referred to as “The 4 C’s” — which refer to “Cut” “Clarity” “Carat” and “Colour” — but don’t make up all factors when grading a diamond to be set in an engagement or wedding ring.

To determine a diamond’s overall value, it’s necessary to include factors such as “Cut Grade” “Symmetry” “Polish” and “Fluorescence” in the assessment, as these factors also contribute to the appearance of a diamond and, therefore, its price. You can learn more about diamond grading here.
