While a diamond owes its beauty largely to nature, the cut of a diamond determines its sparkle factor. when talking about the cut of diamond, we often refer to its shape, such as round, pear, heart, marquise, trillion, or regent cut. according to the gemological institute of america, cut actually refers to how much light is reflected from the facets of a diamond. diamond experts speak of different types of light which enhance a diamond’s beauty.
Brilliance is the total reflected light. fire is the internal light that disperses from the stone causing a rainbow of colours. Scintillation causes sparkling flashes when the diamond moves.
