I was wondering if you would mind doing a computer-generated analysis for this pear to check for brilliance/bowtie/light loss. I'm sorry that I don't have information about the crown or pavilion... Pear brilliant carat: 1.01 length: 9.53 width: 6.24 depth: 2.86 depth %: 45.8% table %: 58% girdle: medium to thick, faceted culet: none polish: good symmetry: good clarity: VS1 color: E fluorescence: medium blue

Unfortunately, an accurate DiamCalc profile can not be created for your stone without the crown/pavilion height/angle information, because the possibilities are endless. I have, however, attached two hypothetical profiles- one of a pearshape diamond having the depth of your diamond (45.8%), and one having a more traditional 61.2% depth. The arrows point to the girdle reflection inside the table. The shallowness tends to have a "breaking up" effect on the facet reflection, creating a rippley "shimmering" effect rather than a symmetrical facet pattern. On the good side, the effect of a "bowtie" is usually obliterated by the shimmering reflection pattern. Again, a very shallow pearshape diamond will look "glassy" compared to others, and will tend to "dull out" when dirty. Rich, Independent GG Appraiser Sarasota Gemological Laboratory

I finally understand what you were trying to explain to me (a picture reallly is a thousand words ) Now I can decide what is more important - my quest for a pear without any bowtie that looks glassy or a more traditional pear with the possibilities of a bowtie or dark areas that looks more like a diamond. I'm sure there are variables in here somewhere... Again, thank you very much!

Rook Cut Rock Total Posts: 294 Last Post: 2/9/2004 Member Since: 10/4/2002	Hello, Well as someone who just finished a search for an outstanding pear, I can tell you that your search will be rewarding, but painstaing. I searched for quite a long time, but then again I was looking for the best of the best. And I believe I found it. First, I don't think you will find a pear with no bowtie that is cut well. A well cut pear will have a minimal bowtie, but to have no bowtie at all typically ends up with a poor cut pear, as shown by Rich's pics. Don't worry about that little bowtie as it just becomes one of the characteristics of the diamond that gives it a life of its own. Just make sure it is not prominent. I have asked countless questions on here about pear diamonds. Do a search for pears, and my user name, and you should find quite a bit of information. Also, check goodoldgold.com. That is where I found my diamond and I know that have a couple of other pears that are fabulous. I purchased the 1.04ct F/SI1, but I also looked at (gog shipped it to me) the 1.14 f/vs2. I am quite sure GOG can help you though. Also, check out the cut parameters at Dave Atlas's website. That is where I started from. Hope this helps! Rook.
