Clarity

When light enters a diamond, it is reflected and refracted out. If there is any
thing disrupting the flow of light in the diamond, such as an inclusion,
proportion of light will be lost. As a result brilliance could be diminished.
The number of inclusions can determine the degree of brilliance.
Inclusions, which are sometimes referred to as "Nature’s Fingerprints", are
usually not visible to the naked eye unless magnified.
Inclusions are ranked on a scale of perfection, known as clarity, which was
established by the Gemologist Institute of America (GIA). The clarity scale,
ranging from FL (flawless) to include (me), is based on the visibility of
inclusions at a magnification of 10 as.The position of inclusion can affect the
value of a diamond. There Are very few flawless diamonds found in nature, thus
these diamonds are much more valuable.
What’s the difference between VVS1 and VVS2? Or SI1 and SI2. The numbers
represent levels with in each grade. THE I’s will be cleaner (have fewer or
smaller inclusions) than the 2’s. This allows for more specific categories.
Inclusions are natural identifying characteristics such as minerals or fractures
,appearing while diamonds are formed in the earth. They may look like crystals,
clouds or feathers.
To view inclusions, jewelers use a magnifying loupe. This tool allows jewelers
to see a diamonds at 10x its actual size. Even with a loupe, inclusions in the
VVS (Very ,Very Slightly Included) to VS (Very Slight Included) range can be
very difficult to find.
The position of inclusions can affect the value of a diamond, you may not notice
a significantly difference between a VS1 and a VS2. However, you should consider
the number, size, brightness nature and position of the inclusions.
Some inclusions can be hidden by a mounting ,thus having little effect on the
beauty of a beauty. An inclusion in the middle or top of a diamond could impact
the dispersion of light, sometimes making the diamond less brilliant. |
