Cutting is where this masterpiece becomes a mirror of light instead of a fascinating pebble. Whether you prefer a round, pear, emerald cut, marquise or heart shape, the shape of the diamond and make (proportion and finish) are both elements of the cut.
The better the diamond has been cut (i.e. the better the make) the more beautiful the diamond will appear. The make is the overall appearance.
If the diamond is pleasing to the eye, it probably has very good angles, good facet junctions, and a nice finish (polish).
The ideal cut allows more lively, brighter and visible spectral colours to appear from the crown facets.
In addition to the angles and proportions, the finish, which includes the overall polish of the diamond, the condition of the girdle (thickness and texture) and cullet (not being nicked, chipped, abraded, out of alignment or off-center), and the symmetry of the facets (meeting at the apexes and correctly positioned) are essential to the beauty and appearance of the well cut and proportioned diamond.
Diamonds are cut from their rough, natural state. The diamond rough is studied thoroughly by an expert so as to decide how the diamond rough should be cut to yield the best value, average weight loss between 50% – 60%. After marking the diamond with India ink sawing and/or cleaving, girdling, faceting and polishing is performed.
