The shape of stones: The secret of a good size (cut - 4C) lies in the symmetry, the balance of the proportions and the talent of the diamond cutter.

​

• The shape of the stone (round, oval, square, ...) is to be considered at the same time than the type of faceting:

• Brilliant cut: crown and breech cut in triangle and kite. The lower part of the stone goes to a central point (culet)

• Step cut: parallel facets (ex: emerald cut)

• Mixed cut: upper part brilliant and lower part in degrees (ex: princess size) or conversely

• Cabochon cut (unusual for diamonds): rounded polished surface, not faceted

• Other cut: brilollette, buff top, plate, ....
