What are the qualities of a diamond ring?

The qualities of a diamond are Colour, Clarity, Cut and Carat or commonly known as the 4c's.

Colour

Most diamonds of gem quality vary in shade from colourless to yellow. Other colours occur in diamonds such as brown, orange, pink, blue, etc. The most intense of these shades are determined as “Fancy” colours. 

Clarity

Diamond clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond. A perfect stone with perfect clarity, or clearness, is rare, and most flaws that do exist in jewellery grade diamonds cannot be seen without looking at the gems through a jewellers loupe.

Cut

How a diamond has been cut, polished, and to what proportions and symmetry, are of utmost importance since these factors determine the life, brilliance and dispersion of the diamond. If these cutting factors fall below standard, the appearance of the diamond will be adversely affected.

Carat

The weight or size of a diamond is measured in carats (ct.). A carat is 0.2 grams and there are 100 points (or 200 milligrams) per carat.

 

What is a GIA / IGI diamond certificate?

The GIA / IGI diamond certificate/report give's you the customer the confidence that the diamond you are buying is at the quality you want and more importantly paid for.

The GIA Diamond Grading Report has the assessment of a diamond’s 4C’s – color, clarity, cut, and carat weight – along with a plotted diagram of its clarity characteristics and a graphic representation of the diamond’s proportions. For standard round brilliant cut diamonds falling in the D-Z color range, the report also includes a GIA Cut grade.



The IGl Diamond Report is essentially a statement attesting to the authenticity of a diamond and provides a reliable and accurate report of its identity and grade based on an internationally recognised system. Each diamond is scientifically analysed by several gemologists who use their experience in combination with state-of-the-art equipment to produce an accurate description of the characteristics of the diamond and the quality of its cut. With its detailed information presented in understandable language, the different qualities of a diamond can be truly appreciated.
