Help Choosing Your Diamond

Carat: Carat denotes the weight of the diamond, not the size. However, knowing the carat weight of a stone can give you an indication of the size. Diamonds with a higher carat are not necessarily better than those with a lower carat, as qualities like clarity, colour and cut are of equal importance.

We stock 0.5ct and 1.0ct diamonds as standard.

Cut: The cut of a diamond refers to the angels, proportions, facets and finishing details of a diamond. The better the cut, the better it will capture the light. A diamond’s cut is graded on a scale of excellent to poor in a meticulous process where graders have to analyse each facet of the diamond and compare their findings to millions of other stones.

Clarity: The clarity of a diamond refers to how clean the diamond is and outlines the level of inclusions and blemishes both internally and externally. Flawless diamonds are incredibly rare and as such come at a premium price. Many diamonds have flaws and imperfections and are assessed and labelled as such using a scale from Flawless (FL) to Included (I1, I2 and I3). The clarity of a stone is graded by the human eye under 10x magnification.

At The Great Frog we typically stock stones with a clarity rating of VS1, VS2, SI1 and SI2. These ratings indicate that the stones are very slightly or slightly included.

Colour: The colour of a diamond refers to how colourless it is. This is graded on a sliding scale with the perfect diamond being labelled as completely colourless (D) all the way to lightly coloured (Z). A diamond’s colour is graded by the human eye using the same methods used to assign a diamond’s clarity.
