What is a "Laser Drill?"
Laser drill hole is a microscopic hole we make with a laser
beam to reach an inner black carbon inclusion so it can be removed
by boiling the diamond with a very strong acid. It is a common procedure
and cannot be detected by the naked eye and sometimes even with
a magnifying glass; an irreversible process.

What is Fluorescence?
Fluorescence as a term means that a diamond will glow (in
blue) under a UV lamp. It was used originally in diamond certifications
as additional information for identification. The impact of blue
fluorescence on price depends on its appearance. For some higher
color stones, fluorescence gives the stone a milky white appearance,
which greatly lowers value. In some instances, the fluorescence
is hardly noticeable and has minimal impact on the stone's brilliance
and value. Fluorescence often adds value to lower color stones as
it gives the stones a whiter, brighter appearance.

What is the effect of "Polish"
and "Symmetry" Lab grades on Brilliance diamonds?
The brilliance of a diamond is determined mostly by the
proportions and the angles of the facets and not by the "Symmetry"
or "Polish" grades stated by the EGL or GIA grading reports
(certificates).

What is "Cut" and “Ideal
Cut “?
The beauty of a diamond is its brilliance called often as “fire"
or "life” , it is determined by the diamond's "CUT"
and a little by its color. The best brilliance (the reflections
of light coming out of the diamond) is achieved by the "Ideal-Cut
" diamond, in round diamonds mathematically proven and in other
shapes determined by trade thumb rules and visual inspection.
