In looking at faceted a couple of questions come to
mind about standardization.
1) What are the usual cuts and what do they mean?
round, oval, pear, marquise, cushion, and emerald. the pear is
like a tear drop, the marquise (also called navette) has two
points like a double ended boat, cushion is like a rectangle, and
emerald is like a rectangle with cut corners. There are many more
cuts, but these are the usuals…
I have seen
references to belly cuts, german cuts and shallow cuts. When
choosing stones to fit a setting, how does one decide on the
depends on the stone, and whether synthetic or genuine. Genuine
stones, especially the more expensive, can vary widely from
standards as they are usually cut to maximize the weight.
Inexpensive genuine stones are frequently cut to calibrated
standards. Genuine stones can be cut very deep or very shallow
and still conform to calibrated standards, and this can affect
the setting you should choose. Synthetic stones are usually quite
close in dimensions. Decide on the cut you like the look of, oval
is the most common cut of colored stones, followed by round > >
2) Are calibrated faceted stones cut to standards?
Are all 8 X 6 ovals very nearly the same size?
Once again, this depends on if the stones are genuine or
synthetic, with the difference mainly in the depth. If a stone is
labeled as an 8x6, it should definitely be 8x6. Genuine stones
will frequently show variance, especially as they increase in
