Certified
or certificated diamonds
Unlike
what you may think buying a certificated diamond
is not a guarantee that what you are buying
is what you are receiving.
For the
following reasons:
1/ Diamond
laboratories do not give you any type of recourse
should their diamond report not be correct.
Only your supplier can do this.
2/
Diamond grading is not an exact science, the only
things you can be absolutely sure all laboratories
will agree upon is the material
(diamond) and the weight
(carat size) as well as the measurements.
Colour,
Clarity and Cut are left to the appreciation
of those expert examiners, working often on different equipment and,
most importantly, different colour samples and lighting conditions.
Laboratories
as the HRD, IGI, EGL and GIA will often give very
different results for one and the same individual diamond.
In fact they may not even be able to reproduce the
same result upon re-examination. Each laboratory has
its own level of consistency with the results, none
are perfect.
We
have seen differences of up to two colours
and two clarities between them, so in the worst scenario, what you
think is a 'G' VVS1 could on another examination,
turn out to be an 'I' VS1. Differences of one colour
and/or one clarity grade are not rare.
This can mean important differences in the price, up
to 35%, so be wary
and seek advice from an expert.
What
differences are there between
'Antwerp, Premium or 'Ideal' cut diamonds.
