Choose Your Diamond

Purchasing a diamond is important, we can help you learn as much as possible about how certificated diamonds are classified and how the cost of a diamond is determined by the 4 C’s.

Which of the 4cs is most important for you - Cut, Colour, Clarity and Carat Weight? 

Cut/Shape

The Proportion of the diamond as well as the shape determines this C. 

Proportion is critical to make the best use of light return. When a diamond is proportioned correctly, light is reflected internally from one facet to another, and then refracted through the top of the stone.
When the cut of the diamond is too shallow or to deep, light is lost through the pavilion before it can be reflected.

Proportion is not the same as shape. Diamonds can be cut into many variances of shapes, dictated by the shape of the original rough diamonds shape.

The traditional diamond shapes are round, princess, Asscher, cushion, marquise, pear,trilliant, emerald, oval and heart. But there are many more shapes

Color

The cape series diamonds range in colour from D – Z, The colourless icy D becoming warmer with a yellow hue as the stones get towards the Z.

Saturated and deep or fancy yellows, oranges, pinks, blues, greens, and other colours known as fancy colours.

In the Cape series the top grade is the colourless D which has pure carbon bond. With the carbon – nitrogen bond the yellow is introduced to bring the warmer side. The differences D to E or Fro G to H is so subtle and it takes a trained eye with years of experience to colour grade a diamond agaist a diamond master set. (link DCLA LAB)

Clarity

A diamond's clarity while checked in a laboratory under high microscopic magnification is determined by using a 10-power magnifying glass and a trained eye.

Almost all diamonds contain some type of inclusions, most are microscopic in size and others can interfere with the light passing through the diamond. That is why the transparency grade is so important. (LINK DCLA)

The more rare the diamond the high the value. A diamond that is free of all inclusions and surface blemishes is very rare and therefore very valuable.

Carat/Weight

This is the weight of a diamond measured in carats. Not the size.

One carat is equal to 100 points, this means a diamond of 75 points weights 0.75 ct.

The carat weight of a diamond measured to 0.001 of a carat on a laboratory scale. With the correct scale it is the easiest to determine.

Important to note, two diamonds can be of equal carat weight, but their physical size and value can differ greatly. This is due to the proportion or cut, colour, clarity, transparency and extra characteristics.

Take the time to read through the 4cs so you can determine which is most relevant to your choice of diamond.

Evaluate your choice carefully, The time you spend now can bring you a lifetime of pleasure.
