Diamond Cut

• Cut is a measure of how a diamonds facets
  interact with light. A diamonds cut grade is a
  measure of a diamonds light performance. A well
  cut diamond offers maximum light return out of
  the diamonds table surface area. In a shallow
  cut diamond, light leaks out of the bottom. A
  deep cut diamond allows the light to escape from
  the sides.

• The less color a diamond has, the higher the
  color grade. Generally, the whiter it is the more
  valuable and sought after the diamond. The
  slightest hint of color can make a dramatic
  difference in the value of a diamond. Color is
  generally the most important characteristic after
  cut.

• The human eye tends to detect a diamonds light
  performance, or sparkle, first and then its color

Diamond Clarity

• Clarity evaluates the number, size, and position
  of inclusions and blemishes inside and outside of
  a diamond. All diamonds except for Flawless have
  inclusions. In fact, almost all diamonds have
  imperfections or what is referred to as
  inclusions. Many of these imperfections or
  inclusions are microscopic and in most cases are
  not noticeable by the naked eye. Eye-clean
  diamonds are the most popular diamond clarity
  grades amongst consumers. An Eye-Clean diamond is
  generally any diamond that is Slight Inclusion
  (SI) level or higher.

Carat Weight

• Diamond weights are measured in metric carats or
  ct. A carat is divided into one hundred points
  a single point is one hundredth of a carat. A one
  carat diamond is 100 points. Diamonds are weighed
  to a thousandth (0.001) of a carat and always
  rounded to the nearest point. A 1.05 carat
  diamond, for example, is described by most
  jewelry professionals as one point oh five
  carats, or one oh five. A fraction of a carat
  weight difference can mean huge difference in
  price of a diamond. A 1.00 carat diamond, for
  example, has more value than a 0.99 carat of a
  comparable diamond quality factors. 

18

• People often confuse the words Carat and
  Karat as they are pronounced the same. Karat is
  a unit of measure used to describe the level of
  purity of gold there is in an alloy.
