How do you choose a diamond?

Here is some brief advice from the Architect / Designer Giansanti:

" A diamond is a mineral and as such is conceived as the fruit of nature, formed over thousands of years, a true example of unique and unrepeatable beauty. Once the diamond is extracted it can be cut to a perfect round, the most common cut used in jewellery, or in to other forms, such as the emerald cut, Princess or Marquis etc. Therefore, in choosing a diamond you must consider its cut. It should also be said that the stone must always be accompanied by a certificate, at least to the international standard of the HRD Antwerp or GIA. Taking only non-coloured stones (the coloured ones are called fancy colours) we have a range of parameters that influence the choice between one stone and the next, the most important of which, in my opinion, are the colour gradation, the purity of the gradation and the beauty and accuracy of the cut. Colour gradation is a value that indicates how pure white the stone is, this value is indicated by a scale from D (diamond) to M. The purity of the stone, that is, the presence of natural inclusions within it, is indicated by a set of values such as IF, VVS, VS and SI. VVS is the diminutive of Very Very Small inclusions, which indicates the presence of infinitesimal inclusions only with a lens with at least 10X magnifications and absolutely invisible to the naked eye. The accuracy of the cut today is judged by a series of values such as cutting, finishing and symmetry, which are summed up in a single judgment that can be optimally referred to as Excellent, such a cut makes stone brilliant thanks to the obvious effects of reflection. There are also other values in the choice of a diamond to be considered, such as fluorescence, which may affect the optical and visual impact of the stone and which can only be evaluated by technical tools in our laboratories. That is to say that the choice of a diamond must be weighted, but above all, you should turn to experts who can tell customers how to read the certificates and help them choose stones that fit their needs."
