Diamond Cut
A) When a ray of light touches the surface of a diamond, part of the light is reflected back, this is external reflection. B) The rest of the ray penetrates the stone and is then reflected toward the center of the diamond. This is known as refraction. C) The ray of light is reflected to the surface, where it is seen as the colors of the spectrum. This is known as dispersion.
The Cut is the factor that determines the brilliance of a diamond. A classic round brilliant cut diamond has 58 facets : 33 on the top, 24 on the bottom, and the culet (1 point at the bottom). Each of the diamond's facets must be placed in exact geometric relation to one another when the stone is being cut. Quality diamonds must be properly cut and not "spread", which means that the proper proportions are compromised to make the diamond weigh more.

Diamond Clarity
FL-EF | Flawless or Internally Flawless. No internal inclusions.
VVS1-VVS2 | Very Very Small inclusions. Very difficult to see under 10x magnification.
VS1-VS2 | Very Small inclusions. Can bee seen under 10x magnification and in some cases to the naked eye.
SI1-SI2 | Small inclusions. Can bee seen under 10x magnification and may be visible to the naked eye.
I1-I2-I3 | Imperfect. Inclusions are visible under 10x magnification and in most cases to the naked eye.
The Clarity of a diamond is based on the number, location, size, and type of inclusions found in the
An inclusion is an imperfection or trace mineral in the stone that is visible under the magnification of
a jeweler's loupe. The fewer inclusions the diamond has; the clearer, more brilliant and more
expensive the diamond will be. A "Flawless" diamond is one that has no
inclusions and is extremely rare and valuable.
