Diamond Education
Diamonds are graded across the world on standard parameters knows as the 4 C’s : Carat, Cut, Colour and Clarity. We’re here to help you understand these details and choose the right solitaire.
Diamond Cut
The cut is an extremely important factor determining the beauty of a diamond. The cut includes the proportions, polish, and symmetry, and these influence the brilliance, fire, and scintillation of a diamond. It is important for a diamond to have well-cut angles and finish for it to sparkle and allow maximum reflection of light. A poorly cut diamond can appear to be dark, dull, and lifeless. It has the greatest overall influence on a diamond's beauty.
The diamond cut scale ranges from:
Diamond Color
Basically, the whiter or clearer the colour of a diamond, the greater its sparkle and thereby its value. While most diamonds are white, not all are truly colourless, they have colour tints.
The GIA has devised a set of guidelines to grade diamond colour ranges from D to Z, with D colour diamonds being rare, totally colourless, and the most expensive. Each letter represents a range of colours based on a diamond's whiteness.

Diamond Clarity
Clarity reflects the purity of a diamond or the inclusions and blemishes in a diamond. This impacts a diamond’s ability to let in light and reflect its brilliance. Inclusions are interior irregularities and blemishes are exterior irregularities. These imperfections are not flaws, but rather the natural fingerprint of every diamond. Often, we can see these only under a powerful microscope or jeweler’s loupe, and they do not visibly affect the appearance or beauty of a diamond. The larger or more numerous the inclusions the less valuable the diamond.
Internationally, diamonds are graded by labs according to the following grades:
Diamond Carat
Diamond carat weight measures how much a diamond weighs. Carat is the unit of measurement for the physical weight of diamonds. One carat equals 0.200 grams or 1/5 gram and is subdivided into 100 points. This allows very precise measurements to the hundredth decimal place.
All else being equal, diamond price increases with diamond carat weight because larger diamonds are rarer and more desirable. However, two diamonds of equal carat weight can have very different values (and prices) depending on three other factors of the diamond 4Cs: Color, Clarity, and Cut.
