The 4 C's

A diamond ring is a substantial addition to your precious Jewellery collection, so it is important that when buying your piece you get value for money, and importantly that you understand what you are buying.

Diamonds are appraised in a rating system called the 4 C's standing for Cut, Carat, Colour and Clarity.

Below is a guide for you to refer to when selecting your next precious purchase.

Zamels Diamond Diagrams Cut


A diamond's cut is expressed in terms of proportions and finish. Proportions describe the angles of inclination and proportional relations between the various parts of the stone, whilst finish is mainly concerned with the symmetry deviations and positioning of the facets. A diamond's cut is its most important feature. A poorly cut diamond will "leak" light out the back, diminishing the stones value. A good cut will magnify the brilliance and liveliness creating a well performing diamond.

Zamels Diamond Diagrams Carat


Carat refers to the Diamond's weight. One carat equals a fifth of a gram. The total carat weight of a diamond contributes considerably to the value of the piece.

Zamels Diamond Diagrams Colour


Diamonds come in a variety of colours. White diamonds are the most common and the most popular. A perfectly white diamond should be crystal clear. The lighter the tint of yellow or brown, the more rare and valuable.

Zamels Diamond Diagrams Clarity


Clarity refers to the appearance of internal characteristics; the fewer the number the higher the grading. Nearly all diamonds contain inclusions or flaws that diminish the stones brilliance. The highest clarity grading is expressed as a "loupe clean" and is completely free of inclusions when viewed by an experience grader through a 10x loupe (magnifier). The lowest clarity grades possess inclusions that are visible to the naked eye.
