superbert diamond girdle

[CareBear]

anyone know why most superbcert diamonds have girdles in the ~2% range? doesn''t this mean you are paying for some necessary carat weight compared to a ~1% girdle?

Isn''t 1% very thin ? Not sure that''s desirable either - chipped diamonds are not desirable.

Not that a thick girdle is practical, but 2% doesn''t seem to qualify for "thick" ...

CareBear:

2% is not an unnacceptable range.

The thickness should not be too thin or too thick which means an ideal thickness would be thin, medium or slightly thick or any combination of these. 2% is an average but falls within these parameters.
An extremely thin girdle would be a girdle so thin that it would be knife edge sharp. . In most cases only a very small area of the diamond girdle is extremely thin.

If the girdle is too thick as in extremely thick, there would be too much weight of the diamond in the girdle and the diameter of the diamond would be smaller than the same weight diamond with a medium girdle. 2% does not classify as an extremely thick girdle and falls within acceptable ideal proportions.

There are instances where certain cutters purposely leave more beef of the stone hidden at the points where certain labs don't measure. Because the labs grade certain areas of the girdle, the area left can be used to hide weight. In any circumstance this just isn't the case in SuperBcert stones as you are concerned with extra weight being left on a diamond with a 2% average..

Hope this Helps..
