THE FOUR CS
IF YOU’RE IN THE MARKET FOR AN ENGAGEMENT RING, YOU’VE PROBABLY HEARD THESE MENTIONED. A LOT. HERE’S WHAT THEY MEAN – AND WHY THEY MATTER.
This is all about the shape and position of the diamond’s facets – considered to be the most important factor in a stone’s beauty. Tiffany & Co. puts a premium on a stone’s beauty and the cutters always go for beauty over weight.
A stone is said to be internally flawless if, when viewed under a microscope, there are no visible internal flaws – things like cloudiness – or external scratches or nicks. Absolutely flawless diamonds are incredibly rare.
This one, you probably know. It refers to the weight of a diamond, with one carat equal to 0.2g. Heavier diamonds are not always more valuable, as other factors like cut and colour also need to be taken into account.
Classic engagement rings are colourless. Every diamond is graded from ‘D’ (colourless) to ‘Z’ (saturated). Tiffany & Co. only accepts diamonds with a grading of ‘I’ level (near colourless) or better.
