Diamond Selling Guide Vol. 2


Another major factor that will affect the value of your diamonds is the clarity. All diamonds are formed over years of heat and pressure which transforms them from carbon deposits to valuable crystals. During the process slight imperfections cause marks to be left in the diamonds. These are known in the industry as inclusions and the fewer the inclusions within the diamond the higher it's value would be. An expert will assess the diamond and grade it on the clarity chart. The most popular diamonds are eye clean meaning they have no visible marks.


The colour of a diamond plays a large role on establishing its value. The more colourless a diamond is the greater it's value. The lack of colour within a diamond is attributed to its purity and helps with light refraction. As the diamonds goes down the colour scale it begins to become a darker and as it goes further down it begins to show hints of yellow. From an aesthetic angle the lower the colour the less desirable the diamond is. However, when the diamond develops a recognisable colour shade the value begins to increase as it develops its status into a coloured diamond. Depending on the colour depth these diamonds can be more expensive than a colourless diamond due to their rarity.

All of these things are taken into consideration by the buying expert when giving a valuation.

To summarize the most important factors to remember number one the size number two the quality which is made up of colour clarity and cut and lastly any certification the diamond has.


A diamond certificate is a document which verifies the authenticity and quality of a diamond. If a diamond certificate is obtained through a credible gemmological laboratory the value of your diamond will be more than one which has not.

This guaranties the authenticity and nature of the diamond allowing you in the event of selling your diamond to obtain a higher value.
