What determines a diamonds worth?
The 4cs namely cut, colour, clarity and carat are the primary factors that determine the true worth of a diamond.
-Cut- This usually means the proportions of the diamond as opposed to its shape (Round Brilliant, Love heart, Pear, Princess, etc.) Every diamond regardless of its shape gets it brilliancy and shine by cutting and polishing the diamond faces to allow the maximum amount of light that enters through its top to be reflected and dispersed back through its top.
-Colour- The best colour for a diamond to be is no colour at all. A totally colourless diamond allows light to pass through it easily, resulting in the light being dispersed as the colours of the rainbow. Colours are graded totally from colourless to light yellow. The differences from one grade to the other are very subtle and it takes a trained eye and years of experience to colour grade a diamond.
-Clarity- The clarity of a diamond is determined by the amount and location of flaws, or blemishes, in the diamond when viewed under 10x magnification. Most diamonds contain very tiny birthmarks known as “inclusions.” An inclusion can interfere with the light passing through the diamond. The fewer the inclusions, the more beautiful the diamond will be. Diamonds have the capability of producing more brilliance than any other gemstone. A diamond that is free of inclusions and surface blemishes is very rare, and therefore very valuable.
-Carat-Weight- The carat of the diamond is the most important aspect when determining a diamonds worth, the carat is the unit used to calculate the weight of a diamond. As the carat weight increases so does its rarity and therefore its price. One carat is divided into 100 “points,” so that a diamond of 75 points weights 0.75 carats. The carat-weight of a diamond is the easiest measurement to determine. Most importantly, two diamonds can be of equal carat-weight, but their value can differ greatly due to their cut, colour, and clarity.
Generally diamonds can be found in two cuts, the round brilliant and fancy cut.
-Round brilliance- The round brilliant shaped diamonds are more traditional. Price would be higher for this. The diamonds are cut in a particular form with numerous faces so as to have exceptional brilliance. The shape resembles that of a cone and provides maximum light to return through the top of the diamond.
-The fancy cut- Fancy cut diamonds are modern and are available in various shapes. the are comparatively cheap. Although fancy cuts are still very popular coming in a variety of shapes for example love hearts and pear shapes—many of which were derived from the round brilliant.
What are diamonds used for?
Diamond is used in jewellery because, when cut by experts, it will sparkle and reflect light in an attractive way.
Diamond’s hardness and high melting point make it useful for cutting tools, such as the diamond-tipped discs used to cut bricks and concrete. Heavy-duty drill bits, like those used to drill through rocks in the oil exploration industry, are made with diamonds so that they stay sharp for longer.
