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. /Kjell |

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.) My understanding is that the general term is "navette", and that the l/w = 2 ratio is called a marquise. 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. It would make an odd-looking pupil, I think. The dark spot is bow-tie shaped. 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. Have you considered one of the "eye" cuts? There's Cleopatra's Eye by Bob Keller, http://www.rockhounds.com/rockshop/g...leopatra.shtml 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. -- Al Balmer Sun City, AZ |

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; http://tinyurl.com/2dk8ak Carl -- to reply, change ( .not) to ( .net) |

The Oval and The Marquise Cut
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.
