The 4C'S Of Diamonds Became 5!

Typically there are four parameters, called the 4Cs that help ascertain the value of the diamond. Namely: Cut, Colour, Clarity and Carat. However at Liali there is a fifth C that encompasses all the other four, i.e. confidence, this comes from Certified Jewellery! Liali believes that the customer has the right to get their jewel authenticated from an independent international source. In doing so Liali has removed the smokescreen from diamond shopping and made the process completely transparent.


Clarity is a term used to describe the size and number of inclusions in a diamond. Being a natural substance occurring from the depth of the earth, almost all diamonds contain minute traces of non-crystallized carbon, the element from which they were born.

Large inclusions interfere with the dispersion of light and therefore affect the diamond's brilliance. The larger or more numerous the inclusions, the less valuable is the diamond. The fewer the inclusions the more rare is the stone.


Mostly diamonds are white or colourless as those are the hues that allow maximum light to pass through.

The scale for grading colours in diamonds starts from D colours – which are white or colourless diamonds. The next slab grades from E to K, wherein the diamonds have a very slight tinge of yellow.

Worldwide, most jewellery is created from diamonds that range from G to J categories, as they provide the best value between the colour of the diamonds and their prices.

To the surprise of many ‘white’ isn’t the only colour diamonds come in. There are a whole lot of others that come in blues, pinks, greens, reds and bright yellows. These are highly prized and extremely rare.


The weight of a diamond is measured in carats. One carat is divided into 100 "points" so that a diamond of 50 points is described as half-a-carat or 0.50 ct., 25 points is described as a quarter of a carat or 0.25 carats.

The larger the size of the diamond the more expensive per carat it will be. For example, a 1ct diamond costs much more than two 1/2ct diamonds and one 30-point diamond costs much more than 30 one-point diamonds.

The Carat measurement of a diamond is actually an assessment of the diamond's weight rather than its size or diameter.

Carat size isn’t the only parameter that determines the quality and price of a diamond.


The cut gives each diamond its unique sparkle and brilliance by allowing the maximum amount of light to enter and reflect back out of the diamond.

When a diamond cutter is given a rough diamond to cut into a finished diamond he has a choice to make:

a. Will he cut the largest diamond that he can from the rough crystal or

b. Will he cut the brightest and most brilliant diamond that he can?

If he goes for the largest cut diamond, he will sacrifice some brilliance. If he goes for the most brilliant, he will sacrifice size.


The 4Cs of a Liali diamond are authenticated by IGI (International Gemological Institute) thus ensuring you get the quality you paid for.

So when you buy a Liali, you can be that sure your jewel is 100% certified for quality
