a Diamond Cut
The cut of a diamond refers to two separate elements:
The way the rough diamond is cut to produce a polished diamond
The shape of the diamond, the different styles of cuts e.g.
Pear, Round, Marquise, Heart shaped etc.
Effects of a Good Diamond Cut
Diamonds are prized
for their brilliance, sparkle and lustre:
Brilliance or Fire - The amount of tiny flashes of light a diamond gives off
through the reflection and refraction of light - the intensity of
the light-reflecting power which maximizes the brilliance
Scintillation or Sparkle - A measure of the light reflected out by a
diamond as it is viewed from different angles which occurs when light bounces among the
diamond facets creating a
really sparkling display
Lustre / luster - The brightness
of an object that shines with reflected light
- Dispersion refers to the prism of light
refracted from within a cut and polished diamond and relates to the
sparkling colors that are emitted from the stone as it is viewed
from different angles
elements may be visible even in their rough state; but in order to
enhance these advantages the diamonds must be cut and polished. A
skilful diamond cutter, or lapidary, is able to bring out all the
brilliance of a diamond, whilst concealing its imperfections, by
choosing the most appropriate cuts and the most appropriate
proportions and symmetry.
