In some ways, cut diamonds are unlike any other gemstone – remarkable geology and chemistry must join together with remarkable human ingenuity to create these truly precious gems. Small differences in the “four Cs” of Cut, Colour, Clarity, and Carat Weight can have dramatic differences on their sparkling beauty, and also on their price! Therefore, it is important that accurate assessments of these factors are taken into consideration when buying and selling diamonds.
