Flaws are to diamonds what stains are to clothes. Just as a
stain is said to be worse when it remains unseen, possessing knowledge about
the 4Cs of diamond quality is commendable. Descriptions like 1.5ct, J color,
excellent cut, VS1 round brilliant are easily recognizable to you, marking you
as an informed buyer. However, imperfections, such as inclusions and blemishes,
present a different challenge, requiring delving beyond the diamond certificate
and the 4Cs for full comprehension.
Numerous inclusions can double as flaws, rendering the
diamond susceptible to damage. Unique stone identifiers also contribute to the
diamond's natural aesthetics. You may have heard of diamond clouds and
feathers, but are you familiar with etch channels or indented naturals?
Moreover, do you understand the implications of terms like "manufacturing
remnants not shown" or "internal laser drilling present" when
they appear on a diamond report? The answers to these questions and further
insights into diamond irregularities constitute the core of this text.
Before delving further, a word of caution: never base your
diamond purchase solely on the contents of a stone's certificate. In case
you're wondering, you read that correctly. If the certificate isn't from AGS or GIA grading labs, always thoroughly examine the stone. This is the only
foolproof method for ascertaining the diamond's eye cleanliness.
The diamond industry boasts a multitude of vendors, both
online and in physical stores, which makes finding one a straightforward task.
Opting for an accredited dealer should be a logical choice. Yet, even when
dealing with a reputable diamond seller, falling prey to diamond inclusions is
easily possible. The reason lies in the fact that most diamond grading reports
offer only a general clarity grading, particularly for stones under 1ct.
For instance, an inclusion characteristic might be labeled
on the certificate as a crystal or feather. However, this presents a problem as
it doesn't provide insight into the type and extent of the feather, nor does it
reveal the specific crystal within the diamond. While descriptors like
"crystal" or "feather" imply something, they leave ample
room for speculation and ambiguity. Such terms lack the necessary clarity
reference for a diamond's inclusions.
Technology comes to your aid here. When dealing with diamond
vendors, engaging with those who employ diamond display technology or providing
comprehensive information about diamond inclusions is advisable. Technological
advancements in the diamond industry encompass the use of sophisticated
diamond-cutting and polishing equipment, as well as specialized cameras and
These cameras are capable of capturing magnified, enhanced
images and interactive 360° high-definition videos of a stone. By examining 40x
videos of the VS2 diamond below, you can identify all visible
inclusions. Your personal observation and in-person viewing of the stone are
sufficient for making an assessment. If the stone is genuinely eye-clean, you
can proceed to negotiate a price for it.

Beware of dealers who demand partial payment before
disclosing clarity details of a stone. Similarly, exercise caution with
brokers, as many are primarily motivated by profit. They might sell you an
apparently eye-clean princess cut diamond with hidden inclusions in the corners
of its square shape. Subsequently, the stone could chip unexpectedly. The GIA
employs a plot, often referred to as a 'map,' illustrating the diamond's
geometrical shape, a feature present in every GIA certificate (see the bove example).
The clarity plot pinpoints the exact location of inclusions.
Using red and green markings, GIA isolates the precise position of specific
internal clarity characteristics or blemishes. A combination of red and green
markings signifies inclusions extending to the stone's surface, such as
cavities, etch channels, and laser drill holes. Black markings typically
indicate the presence of extra facets. It's advisable also to peruse the
comment section of a GIA or AGS certificate to gain further clarity details. As
you embark on your next gem shopping expedition, keep an eye out for the
following explanations of diamond inclusions.
