The Oval and The Marquise Cut
 

I wonder if there are standard measures for these. I would like to
have a "fat" Marquise, at least fat compared to what I've found when
googling around. Ideally it should fit within the figure known as
"vesica piscis", more or less. (A somewhat pointy almond or a "fat"
Marquise cut explains the figure.)

I also read about oval cuts that there is something called the bow-tie
effect. Some kind of shadow that is usually seen as an imperfect cut.
The stone I want to have made is supposed to resemble an eye. I wonder
if there is any way to use this bow-tie effect so as to give the
illusion of the eye's pupil. Any other tip on how to achieve this
would of course be greatly appreciated.

The stone is supposed to be noncolored. If the form is not 100%
correct I guess the fitting could be done in a way to make it look
more like I want it, but most of all I want the stone itself to come
as close as possible to the ideal.

My understanding is that the general term is "navette", and that the
l/w = 2 ratio is called a marquise.

It would make an odd-looking pupil, I think. The dark spot is bow-tie
shaped.

Have you considered one of the "eye" cuts? There's Cleopatra's Eye by
Bob Keller,

Dan Clayton has a suite of "eye" ovals at
http://www.speakeasy.org/~dclayton/

You might want to ask on the USGF Faceter's List, which has amateur
and professional cutters with a wide range of experience. It's at
http://groups.yahoo.com/group/usfgfaceterslist/ You'd have to sign up
for Yahoo groups, then the list, in order to post, but I think you can
search the archives without joining.

Can we assume you're speaking of a diamond?

There are THOUSANDS of cut designs (several with 'eye' in the name to
denote an attempt to create an eye-like effect) but many 'unusual' cuts
are used on 'semi-precious' gem material. Also, custom cuts can be
designed for specific pieces of rough to minmize waste. So, a custom
cut, or some pre-existing cut designs 'could' be tailored for a diamond.
I suspect finding someone to perform the cutting could be extremely
expensive.

here's a small sample;

If you contact Jeff Gram, he can probably make any cut you want.

In rec.crafts.jewelry almost on Sun, 28 Oct 2007 18:55:27 -0700 a
smoke signal from kjelleman rang out, which was
heard to say :

I wonder if there are standard measures for these. I would like to
have a "fat" Marquise,

sounds like a bit of spam I got the other day...

The Oval and The Marquise Cut
 

I put my answer here and hope that everyone will see it. Thank you all
for responding.

The rather large piece is centerstone for a diadem and I was thinking
of crystal. Perhaps needless to say, diamond is way out of my league
here. :-)

However, I found a prism in a second hand-shop that will do nicely, at
least for a prototype diadem, so my question was a bit premature. I
might return to this friendly and well informed forum in the future
for further advice and, again, thank you all for responding to my
post.

My best,
