The 4Cs
Cut. Carat. Colour. Clarity.
Understanding The 4Cs
When selecting a piece of diamond jewellery, there are important considerations to take into account namely cut, carat, colour and clarity, the so-called 4Cs. Having an understanding of these features is essential in making the correct decision.
Cut
In many ways, the cut of a diamond is the least understood of the 4Cs. It is often thought the cut of a diamond specifically refers to its shape.
In fact, the term “cut” also includes its angles, proportions, polish and symmetry. The way a diamond is cut determines how light enters and leaves the stone, which affects its “life” and “fire”.
At Ronald Abram, cut is the most important of the 4Cs as it’s the most noticeable of the characteristics. So our advice, is to always seek diamonds cut to the most perfect proportions.
Carat
The number of carats in a diamond refers to its weight. There’s a common misconception that the heavier the diamond, the more valuable it will be.
However, factors such as cut, clarity and colour should also be considered when determining value. For this reason, smaller diamonds can sometimes be worth more than larger diamonds with inferior characteristics.
Stones of equal weight can also vary significantly in value.
Colour
Diamonds are graded on a colour scale established by the Gemological Institute of America (GIA), ranging from D (colourless) through to Z.
While colourless diamonds are the most rare and therefore the most valuable, beautiful diamonds exist within every category of colour.
Clarity
Imperfections or inclusions occur naturally in diamonds. The number and location of these inclusions is ranked on a scale of clarity from Flawless (FL) to Included (I) by the GIA.
Such imperfections are not readily visible without magnification, and the differences between each category on the scale are very subtle.
Fancy Color Diamonds: Everything You Need to Know
Color plays an important role in determining the value of a diamond, and this is especially true with fancy colors. Let’s explore the history of the Fancy Color Diamond, learn the natural phenomena behind their formation, and discover how color affects their value.
When you think of a diamond, you envision the most brilliant bright white. Now imagine a cherry red. Bubblegum pink. Lemon yellow, glacier blue, pumpkin orange, mint green, violet purple. These vivacious colors are just a few of many in which diamonds naturally form. In fact, diamonds come in almost every hue imaginable. These prismatic gems are called Fancy Color Diamonds.
Yellow Diamond
rare & desirable
Unlike white diamonds, the cut, weight, and clarity are not as important as the colour. In fancy coloured diamonds, colour takes precedence over everything else. As an example, a smaller diamond with a higher saturation can be more valuable than a larger diamond with less saturation.
Clarity in coloured diamonds is also not as important as with white diamonds. For instance, two fancy intense coloured diamonds of comparable sizes – one having a slightly lower clarity grade than the other – will not vary considerably in price.
In terms of cut, other than an emerald cut or round brilliant cut which are priced higher, most fancy coloured diamonds in all other cuts are similarly priced.
Coloured diamonds are a beautiful alternative to white diamonds. At Ronald Abram, we have a large selection of coloured diamonds in all shapes and sizes.
White Diamond
Classic appeal
Originally cut by hand, antique diamonds have become increasingly rare. Displaying a soft glow that retains their classic appeal and sought after by diamond and history connoisseurs alike, they recall a by-gone era of romance and intrigue.
