Christmas can be such a romantic time of the year, what better time to search for the perfect engagement ring for a loved one.

Don’t know where to start, no problem, we have put together a rundown of the ‘4cs’ to help you better understand the characteristics of a diamond and what makes it sparkle or not… , cut, clarity, colour and carat.


The Cut is the shape of the diamond. Many week or even months, of work go into cutting and polishing diamonds so that they catch the light just so. The way a diamond is cut determines its brilliance and sparkle. This type of cut of course is all down to personal taste and what you feel would suit you or your partner best. Take a look at the diamond shapes below to see which one you are most drawn to…

After the cut, colour is largely considered the second most important trait when choosing a diamond.

Colour reveals itself as a pale yellow in a diamond. Therefore, a diamond’s colour grade is established on its absence of colour, so the less colour a diamond has, the higher its colour grade.


The Flawless diamond, the absolute pinnacle of perfection, a rare quality in anything but especially in diamonds. The Clarity is a measure of the degree and size of the small (birthmarks) imperfections that occur in almost all diamonds, so the less imperfections the better the diamond. Here are some grading examples:

  • Very, Very Small Inclusions (VVS1, VVS2) are flaws that are only visible under high magnification. These are also very rare.
  • Very Small Inclusions (VS1, VS2) have inclusions which are not visible to the naked eye which means they are of a very high quality.
  • Small Inclusions (SI1, SI2) diamonds have small inclusions that may be visible to the naked eye but are of excellent value.

Carat weight

Carat is a measure of a diamond’s weight. A diamond cut can often impact on how generous the carat weight will appear. Originally diamonds were weighed by using carob seeds, this is where the word Carat was derived. One carat is 0.2 grams and incredibly less then 5% of diamonds weigh more than this.

I hope we have given you enough information to feel armed and ready to begin one of the most exciting and probably most important shopping trips you will encounter in life, so it’s one you want to be getting right.
