A Note on Diamond Cut Grade

One of the questions we are asked frequently relates to the cut grade of our diamonds. Australian clients are particularly interested in purchasing a beautifully cut diamond. For this reason, we set our minimum cut grade standard at "VERY GOOD" to ensure maximum brilliance, fire and scintillation. Where applicable this cut grade will be evident on accompanying certification alongside other details including carat weight, colour and clarity. For certification, we favour GIA amongst some of the World's most respected diamond grading laboratories.
