The Gemological Institute of America (GIA) created the first, and now globally accepted, standard for describing diamonds which is referred to as the ‘Four C’s of Diamonds’ – the measures of Colour, Clarity, Cut and Carat Weight. This is the universally accepted method for assessing the quality of a diamond, so that jewelers can communicate to customers exactly what they are about to purchase. If you are planning to buy your special lady a diamond engagement ring, then you would be well advised to learn a little bit more about what makes this the precious and sought after stone in the world.
