Diamond Clarity Chart
Why is a
Diamond Clarity Chart necessary and what is the meaning of Diamond Clarity?
Definition: The clarity of a diamond relates to exactly how clear a
diamond is. It
describes the presence, or absence, of Inclusions (flaws) within the diamond and
any blemishes on its surface. These inclusions disrupt the flow of light in
the diamond so that some of light reflected will be lost and the clarity
of the diamond subsequently diminishes.
Diamond Clarity
Chart - The Quality of the Diamond
The quality of a
diamond, including Diamond Clarity, is one of the 4 C s of
diamond grading (Cut, Color, Clarity and Carat Weight). These grades provide an
excellent guide to the quality of a diamond. The numbers, sizes, colors, locations and
visibility of any inclusions and / or blemishes in a diamond can effect the relative clarity
of a diamond and its quality. The majority of
Diamond Inclusions cannot be seen
by the human eye so systems have been developed to grade diamond clarity.
The different types of diamond grades reflecting clarity are detailed on
the Diamond Clarity Chart.
Diamond Clarity
Chart - The Grades
Diamonds are graded on a Diamond Clarity Chart ranging from high
quality, rare and expensive flawless to imperfect and cheap diamonds.
As the majority of inclusions cannot be seen by the naked eye they are
located by a jeweller under a 10 power magnification and then graded
according to their clarity. The grades and levels are described on the
Clarity Chart. An excellent guide when choosing diamonds.
