1 - Ask for a GIA (Gemological Institute of America)
report. The GIA are the creators of the famous 4Cs grading system and the
leading authority on diamond grading. You may be surprised to know that the GIA
are a not for profit establishment and that they invest all of their revenue in
equipment, training and research. Every wholesale jewelry in the world is compared to the GIA and its not uncommon
for the GIA to downgrade diamonds that have been previously graded by other
laboratories because of their superior grading techniques and technology. As a
result diamonds graded by other laboratories with apparently the same
attributes are usually cheaper than a GIA graded diamond. As all GIA grading
laboratories are integrated and strictly monitored for quality control,
verifying your diamond report online with the GIA is much easier than with the
other grading labs who operate on a more disparate basis.
2- To ensure that you are getting value you must know the Carat (weight),
Cut(shape), Colour and Clarity (visible natural inclusions in the stone).
Colour and shape are a matter of choice but clarity should be more of a careful
consideration. We would strongly recommend that you choose a diamond with a
minimum of SI2 in clarity
do not purchase a diamond which is graded as I1 2 or 3 as these diamonds have
inclusions visible to the naked eye. For round diamonds it is equally important
to know the Cut grade (different to the cut shape) other shapes known as fancy
shapes such as princess or emerald diamonds dont have a cut grade on a GIA
report (beware of retailers who give you a cut grade for shapes other than that
of a round diamond as the GIA do not have a cut grade for fancy shapes). Other
vital attributes include polish and symmetry this applies to all shapes. We
only supply diamonds with Very good to Excellent grades across the cut,
symmetry and polish. We would suggest that you avoid any diamond with poor/fair
to good grades across any of these attributes. Why is this important? A wholesale silver jewelry is like a tiny set of mirrors that interact with light
to create the stones appearance. Every angle and every facet affects the amount
of light returned or lost. Therefore the quality of the cut, symmetry and
polish determines a diamonds brightness, fire and scintillation.
