The 4 C’s – Clarity

Are you clear on ‘clarity’?

The clarity of a diamond is how clear or flawless the gemstone is. Clarity is affected by ‘inclusions’ which are flaws on or in the stone. Grades of clarity range from flawless (FL), the purest diamond grade, to inclusions visible to the naked eye (i3). The less flaws a diamond has, the more valuable it is.

Diamonds can have 2 types of flaw – inclusions and blemishes

Blemishes are surface flaws such as scratches and pits, whilst inclusions are flaws within the stone itself (these can include air bubbles, cracks, and non-diamond minerals). All flaws are called inclusions for the purpose of grading diamonds.

It’s also worth noting that diamonds are graded for clarity under 10 to 30 times magnification!

Here’s a top tip – you can markedly reduce the cost of a diamond if you see that the inclusions will be hidden behind the mounting and therefore won’t affect the overall appearance of the stone.
