Understanding
the 4C’s of diamonds

Choosing a diamond is an important decision for anyone. Not only does Rosdave Diamonds aim to educate customers through the entire diamond buying process, but also we offer competitive prices for the best grade diamonds. Rosdave subscribes to 4C’s of Diamonds. According to De Beers “The 4Cs are a set of objective and widely accepted standards used by jewellers and gemmologists to compare diamonds.”

All diamonds have traces of their growth history. In gem-quality diamonds, this concerns minute internal and external characteristics, graded under Clarity.

In gem-quality diamonds, this concerns minute internal and external characteristics, graded under Clarity.

The weight of a diamond is expressed in carats. One carat = 0.2grams and one carat equals 100 points.

Fire, brilliancy and scintillation of a diamond are largely determined by the proportions of various parts of the diamond. Finish grade mainly evaluates the symmetry.

Most diamonds are colourless to slightly tinted. The colour grade is determined by comparison with a series of masterstones, the best grade being colourless ( D, exceptional white + ).

Diamonds can also occur in all sorts of “fancy colours”, Red, Pink, Blue, Green, Orange, Yellow and Brown.

When purchasing a fancy colour diamond, the colour intensity – the deepness or richness of the colour – is the most important consideration. The more intense the diamond’s colour, the rarer and more valuable the diamond will be.
