Boyfriend/soon-to-be fiance and I were at the mall last night and he suggests we go into Kay Jewelers. Of course I say yes because I love looking at diamonds, no matter how overpriced they are! He was so impressed by my knowledge of cut, clarity and pricing, etc. that after we left he said that he thought I should write down what I want for all the areas that are important and give it to him. I''m sure you will agree that this is an amazing opportunity for any woman to be sure she gets the right stone. So here''s my question: Would anyone out there care to help me in terms of the following (I like it to look a little bigger)I appreciate in advance anyone who''d like to copy and paste this info onto the forum. I think the charts are really hard to read and I''d like to give him something that will be easy for him to refer to when looking at a lot of stones at once. Thanks so much!

What's the most you would pay?: expect to pay about 5% off of Rap give or take a nickel for an ideal cut stone.

We just scanned the open market and didn't find anything that we'd put our name on... Perhaps one of the dealers has a stone like this in their private stock... The market in Antwerp just closed down for a three week summer holiday... Know that "anything" ideal cut in the 0.90 - 0.99 carat range is extremely difficult to come by because the cutters are better off financially to cut a one carat stone with lower proportions than they are to produce a 0.98 carat ideal cut puppy.

Thank you for doing that work for me. Much appreciated. Am I correct that the carat weight will save us money? What's a Rap. And what's a fair price for such a stone?
 
http://www.niceice.com/raptrap.htm explains Rap... And for those of you who are wondering, Martin Rapaport has already seen it

You will save money buying a diamond in the 0.90 - 0.99 carat weight category as opposed to buying one in the one carat range because there is a price increase which occurs between the 0.99 and 1.00 carat marks. This price increase is imposed by DeBeers and is not a price increase that was created by the dealers so don't blame us! As an example, the difference between Rap on a 0.99 carat, F, VS-2 and a 1.00 carat, F, VS-2 round brilliant cut diamond is $1,400.00 per carat - that's the weight of the diamond multiplied by the per carat price for the stone, not an overall difference of fourteen hundred dollars... But as we stated previously, it can be quite a challenge to find "anything" in the 0.90 - 0.99 carat weight category because in this instance a cutter would have lost $1,400.00 per carat for one point in weight... 100 points to a carat, just like there are 100 pennies to a dollar... We have a cutter who just offered us a 0.99 carat princess cut stone and he's whining like a beat dog over the loss...
 
What about if she was looking for a slightly shallower stone with more top diameter spread? Is there a range that you would recommend R&T for a nice looking stone with no fish-eye and not too much white brilliance over fire?
 
Also R&T...you note pav angle to 40.9. What happens when the pav angle hits 41? I ask because I have been plugging stones in the HCA recently that have steeper pav angles, such as 41.1, 41.3 etc. Obviously the HCA penalizes them and gives them a lower score. But change that SAME STONE (almost regardless of what the other dimensions are) pavilion angle to 41 and your HCA score seems to almost always drop under 2.0..making this an 'excellent' make stone. Yet you note 40.9 as the top of the range. So what happens if a 40.9 stone really is 41 and then how does it change again to 41.1. I know that pav angles are very sensitive to changes--but can you clarify this particular finding?
