The 5 C’s
Traditionally, diamonds are classified by just the four C’s: Cut, Carat, Colour and Clarity. At Ro Copenhagen, we go beyond the standard industry classification by including a fifth C: Character of a stone.


Cut
The shape and proportions of a diamond are determined by its cut. Of all existing diamond shapes, the most recognised is the brilliant-cut. At Ro, we also use rose-cut diamond stones in our designs. The subtle beauty of rose-cut stones is that they impart a soft diffused light, whereas a modern brilliant-cut stone shines in a more striking way.


 

Carat
A carat is a standard unit to measure the weight of a diamond. One carat equals 200 milligrams. This can be divided into points, where 0.75 carats = 75 points. A diamond’s value varies according to its number of carats and its rarity. Diamonds may equal in weight but vary in price due to the difference in quality. This means that a smaller diamond with a high carat weight may be more valuable than a large diamond with a lower clarity, colour or cut.


 

Colour
Diamonds are graded from D (colourless) to Z (light yellow). The closer a diamond is to colourless, the more extraordinary and rarer it is.


 

Clarity
All diamonds have imperfections called inclusions. These are formed deep within the diamond and occur naturally.
Clarity refers to the presence, visibility, number and size of inclusions in a diamond and is graded from flawless to included.


 

Character
At Ro, we strongly believe each diamond has personality. We work to ensure our diamonds have a strong quality of character shining through along with our other 4 standards.
