Surface
Quality
|
|
|
All
natural gems can have inclusions
or blemishes,
and pearls are no exception.
Cultured pearls are organic,
so blemishes or surface characteristics
can develop as the oyster is
creating the pearl and applying
the layers of nacre.
A spotless pearl is extremely
rare and valuable |

Symmetry |
|
|
The
symmetry of a diamond refers
to the alignment or arrangement
of the diamond facets and affects
a diamond’s ability to
refract light. In order to have
good symmetry, a diamond’s
facets must be cut exactly to
specific proportions. All facets
should be the same size and
shape and the facets on the
bottom (pavilion) should match
up well with the facets on the
top (crown). When choosing a
diamond, look for excellent,
very good or good ratings on
the grading report.
