The 4 C’s - A Quick Lesson

Before you even walk into a jewelery store or shop online you should acquaint yourself with the 4 C’s. This grading system was created to set a standard that the world could use when grading diamonds. This means whether you are in the UK or shopping in America you can trust the 4 C’s grading system. Keep in mind that if you are looking for a fancy coloured diamond, like a purple diamond ring, the system will be similar but the Clarity will be of little importance.

  • Cut
  • Colour
  • Clarity
  • Carat


Let’s take our example of a purple diamond ring as it is so rare and one of the “must-haves” for any real jewelery collector. Contrary to popular belief, the cut of a diamond is not its shape but rather how proportioned the dimensions are so that the diamond will sparkle and look its best. For a colourless diamond, a bad cut can mean a dull diamond with no brilliance.

The right cut on a fancy coloured diamond, on the other hand, should allow the most amount of light to remain within the diamond to really show the incredible natural colour.

For a fancy coloured diamond, the colour range is described in intensity. The GIA offers a helpful guide to describe the variations. These range from faint or light (lowest grade) to fancy intense and fancy vivid. Not only will this reflect the beauty and richness of the colour but it will also reflect in the price. For fancy colour diamond the colour is most important so consider a smaller carat with a higher colour grade if you have a specific budget in mind. The experts at Asterria can help you choose the perfect diamond.


For colourless diamonds, this is another critical factor, as inclusions and cloudiness can drastically undermine the worth of the diamond. In fancy coloured diamonds, this is less of an issue as the colour hides most natural flaws.


Often confused with the size, the carat actually refers to the weight of the diamond, which does not necessarily speak to the size of the piece. Also, when reviewing your particular spending preference keep in mind that the carat and colour will be indicative of the price. In the fancy coloured diamond world, for example, the rarity of the colour will also be a factor.

For a purple diamond ring, which is incredibly rare and unique, the price begins in the thousands. This also means its a worthy investment that will appreciate considerably.

Where to Shop

Last but not least, if you want to make sure you are only getting the highest quality and best diamond on the market you need to know where to shop. Always choose a certified diamond dealer that can provide you with a GIA or other accepted standard certificate in the industry. Long-standing companies, like Astteria, have earned their reputation as one of the best diamond centres in the world.
