Fun Fact

The name diamond is derived from the ancient Greek “adamas” meaning unbreakable, untamed and unconquerable. Diamonds have been treasured as gemstones ever since they were discovered.

Carat Weight

Is the measure by which diamonds are weighed. One carat is equal to 0.20 of a gram. When weighing less than a carat, the diamond’s weight is expressed in “points”: each carat is divided into 100 points, for example 0.75ct = 75 points 0.50ct = 50 points 0.25ct = 25 points When thinking about the size of a diamond it is important to realise that the weight alone does not determine the diamond’s value. Two diamonds both weighing one carat can be priced differently depending on the clarity, colour and the cut.


Cut refers to both the shape of the diamond and also the quality of the finish. When determining the cut grade, the symmetry, polish and proportions are all evaluated. The beauty of a diamond therefore lies within its complex proportions and how they affect light performance. The result of a well cut diamond are three attributes visible to the naked eye: its brightness, its fire( flares of color emitted) and scintillation which describes the flashes of light. There are five main cut grades: – Excellent – Very Good – Good – Fair – Poor


This is a measure of the minute characteristics both internally and externally, which are naturally formed in the growth of the stone. Characteristics range from small black dots and hairline fissures invisible to the naked eye, to large inclusions that are obvious even without a magnified loupe. The clarity grades are as follows: IF-internally flawless VVS- very very slightly included VS-very slight included SI-slightly included I1-I3- visibly included


Diamonds naturally come in a variety of colors. Although most people think of diamonds as colorless, truly colorless diamonds are in fact extremely rare. Most diamonds used in jewellery are white to slightly yellowish or brown.
