Shopping for diamonds is confusing. Should you pick the largest stone or something more modest. How do you know what to choose?

Often when you start thinking of buying a diamond you fall into the trap of reading too much conflicting information online, you may even seek the advice of an ‘expert friend’. The facts simple. People wear diamonds because they sparkle and selecting a diamond for it’s fire and brilliance can only be done by looking at it in person with your own eyes.

Diamonds are valued based on the 4’C’s (Carat, Colour, Clarity and Cut), but they are purchased with a fifth C in mind – Cost.

Below we have broken down the five C’s of diamonds in an easy to understand format, but if you need a bit more information there is a downloadable GIA guide below.

Diamond Carat – Carat is a measurement of weight not of size, this is often confusing until it’s broken down. Diamonds of the same carat weight can have very different cut proportions. If you diamond is cut deeper or more shallow it will appear very different in size.

Diamond Colour – Colour is the ability to see cool or warm tones in a diamond with your naked eye.

Diamond colour is objective and solely based on personal preference. We often help clients select colour of diamond based on the type of setting or colour of gold the diamond will be showcased in. Jewellery in white gold is often paired with diamonds in a cool colour range whereas jewellery in yellow gold is often paired with warmer colour diamonds. It is always best to match your center diamond to a similar colour tone of the accent diamonds in your setting.

Diamond Clarity – Clarity is the ability to see internal characteristics in a diamond with the naked eye. Diamond clarity is definately something you need to see in person. People often rule out certain clarity grade diamonds because they believe them to be low quality or undesirable but this is not the case.

Not all inclusions are the same. Often a diamond with white feathers can be graded the same as a diamond with black carbon inclusions. These diamonds will look very different and you will only know by seeing them up close.

Diamonds of ‘I’ clarity can be incredibly good buys if the inclusions are white or easily hidden by the settings claws. Don’t rule out ‘I’ clarity diamonds.

Diamond Cut – simply put, Cut is sparkle and has nothing to do with the diamonds shape. A diamonds cut is a combination of angles, measurements and mathematical tables. It is the most confusing aspect of a diamond but it all boils down to one thing –  SPARKLE!

The better the diamonds cut the more fire and sparkle the diamond will have. Many people believe that this is the most important aspect of a diamond. A well cut diamond will sparkle more and in many instances the sparkle or refraction of light can hide inclusions.

Diamond Cost – Cost can vary so much, but why?

A diamonds cost is determined by the combination of the 4C’s, but as you have just learned, each of the ‘C’s’ can vary. The bottom line is more desirable stones will cost more.

Selecting a diamond really comes down to looking at it in person. In person viewing is something Excel offers for all diamonds we sell.
