Diamond Education

The colour of a diamond refers to its degree of whiteness or yellowness. Higher quality diamonds are typically colourless, while lower quality diamonds may have a slight yellow tint. When choosing the colour of your diamond, consider the shape and the metal it will be set in.

For example, for white metals like platinum or white gold, we recommend selecting a colour grade between D and G. However, if you are setting the diamond in yellow or rose gold, you can go as low as a J colour since the metal's reflection tends to conceal colour traces. In the case of elongated diamonds with shallow cuts, such as oval and pear shapes, it's advisable to stay within the D-G colour range.

Clarity refers to the presence of natural imperfections in diamonds, such as internal air bubbles and markings. As you move up in clarity grades, these imperfections become less visible to the naked eye. Clarity is assessed using a 10x magnification loupe, where any visible imperfections are noted and graded accordingly.

We recommend not choosing a clarity grade lower than SI2. However, it's important to note that not all SI2 clarity diamonds are eye clean, as some may have large black inclusions visible without a loupe. Our general recommendation is usually within the FL-SI1 clarity range, depending on the client's specific requirements. For the best value for money, consider diamonds with a clarity grade between VS2 and SI1, as they offer high quality without the price of a flawless diamond.

Cut grades are specifically assigned to brilliant cut (round) diamonds, while other shapes receive polish and symmetry grades. For brilliant cut diamonds, we recommend a triple excellent grading, which signifies excellent cut, polish, and symmetry. This combination maximizes the diamond's fire and brilliance.

Carat is the unit of measurement for a diamond's physical weight. While carat weight is important, especially for those seeking a specific size, the diamond's measurements are also crucial. The cut of the stone can influence how large it appears. For elongated shapes like oval or pear cuts, the ratio of length to width is vital.

By choosing the right ratio, you can achieve a larger-looking diamond without necessarily increasing the carat weight. Consider the shape and proportions of the stone to make an informed decision.
