Factors Affecting the Quality of Loose Diamonds
Jewelry industry experts assess and systematically discuss these issues. If not, it would be
impossible to evaluate one diamond against another. Additionally, assessing and describing
characteristics to sell loose diamonds is possible.
In all other respects, the price of a diamond rises with carat weight since larger diamonds are
more valuable and scarce. But depending on three other 4Cs—clarity, color, and cut—two
diamonds of the same carat weight might have different values.
Color
Most gem-quality diamonds are evaluated for color based solely on the lack of color. A diamond
with the same structural perfection as a diamond and the same colorlessness as a drop of
colorless water is worth more. The D-to-Z color grading range from GIA is the sector most
extensively used grading scale.
The scale runs from the letter D, which stands for colorlessness, to the letter Z, which represents
an increasing presence of color. Many of these color differences are so minute that they are
undetectable to the untrained eye, but they significantly impact the ability to sell loose
Clarity
Diamonds naturally form when carbon is subjected to intense heat and pressure in the earth
interior. The quantity, size, relief, kind, and position of these qualities must be considered when
assessing a diamond clarity and how they affect its overall appearance. Although no diamond is
entirely pure, the closer it is, the more valuable it is.
Six categories comprise the GIA Clarity Scale, some further divided into eleven distinct grades.
Only a skilled diamond grader can spot many inclusions and flaws since they are often too small
to be noticed. Because of this, it is crucial to measure clarity properly and expertly.
Cut
The brilliant glitter and light transmission of diamonds are well known. Although people
frequently associate a diamond cut with its form, the accurate measurement of its cut quality is
how well its facets interact with light.
Precise creativity and workmanship are needed to shape a stone so that its proportions,
symmetry, and polish produce the brilliant return of light only attainable in a diamond. The cut
quality dramatically influences the diamond final beauty and worth.
The GIA Cut Grading System assesses seven factors for the typical round brilliant diamond. The
diamond overall face-up look accounted for the first three factors, brilliance, fire, and
scintillation. The remaining four factors—weight to durability, polish, symmetry, and
durability—evaluate the craftsmanship and design of a diamond.
Weight
Carats are a unit of measurement used to describe a diamond weight. Two hundred milligrams
is the definition of a carat in metric units. This makes measurements up to the hundredth
decimal point.
A jeweler may use a diamond points to determine its weight if it less than one carat.
Diamond weights greater than one carat are expressed in terms of carats and decimals.
The fact that not all diamonds are made equally is among the first things most people learn about
them. Each diamond is different. Diamonds vary in a wide range of sizes, shapes, and hues and
have various intrinsic properties.
Every polished diamond is worth something. Several variables determine the value when one
wants to sell loose diamonds. One of those factors is a rarity. Diamonds with specific
characteristics are uncommon and more expensive than diamonds without them.
