Understanding the 4 C's of Diamonds

Many people have heard of the 4 C's of diamonds but don't really understand what they mean and how they

impact a purchase decision. The 4 C's were developed by the industry's peak standards body - the Gemological

Institute of America - and adopted universally by respected jewellers.

We recommend you seek advice from our highly trained staff members to ensure you understand the importance of

the 4 C's and to help you avoid the pitfalls of purchasing a diamond not appropriate to your occasion.

Here's what you should consider before buying a diamond:

Cut

Of all the 4 C's, cut has the greatest effect on a diamond's beauty. Two diamonds of the same size, colour and

clarity will look vastly different to the eye if cut differently - one may look brilliant and bright, the other dull and

drab. The better quality the cut the more brilliance and beauty the diamond will have. Ask your DGA retailer to

show you the difference that an exceptional cut can make to a diamond's beauty.

Colour

A truly colourless diamond is extremely rare. Most diamonds possess varying degrees of colour creating substantial

differences in value. The highest grade for a diamond with absolutely no colour is D and letter grades are assigned

alphabetically all the way to Z. An 'icy white' diamond is typically D, E or F. However, some people like the 'warmth'

of a I, J or K colour. Within a given budget, you should seek advice from your DGA retailer on the best balance of

clarity, cut and carat to find the perfect diamond for your purchase occasion.

Clarity

Diamond clarity is symbolic of 'purity' - the more flaws, the less valuable the diamond. Flawless, VVS (Very Very Slight),

 VS (Very slight) and SI1 (Slight Inclusion 1) have the least 'inclusions' or flaws. SI2 (Slight inclusion 2) is borderline

where inclusions become visible to the naked eye. I (Inclusion) rated diamonds have obvious inclusions or flaws. Your

DGA retailer can offer advice on the best balance of quality and value for your diamond purchase.

Carat

Diamond carat is the standard used to measure diamond weight. A carat equals 1/5 of a gram. As diamonds increase in

size, their cost tends to increase exponentially. Weight does not always enhance the value of a diamond - particularly if

it is cut badly. Indeed a good cut can enhance the perceived size of a diamond. You should consult with an DGA

member regarding the question of carat weight.
