So i have noticed 3 different(so far) styles of a diamond cushion cuts. Is there a preferred style? Also does the pricing differ among these?

Cut Info
I am still wondering if there is a different per carat price on these different cuts if anyone knows.

Per carat price = selling price/weight. Cut is only one factor (variable) in selling price.

With an "ideal cut" diamond, there is a standard by which one can judge its value, if one assumes all other factors (clarity etc.) are equal. Without that standard, no meaningful comparisons can be made. That leaves it up to the seller's hype.

There are certainly different prices from different suppliers, but that is most likely more a result of other factors than the quality of the cut.

Thanks again Bill,
Yeah finding two stones with the same parameters and different cuts of equal symmetry from the same supplier would surely be difficult. It is more a question of if there is a standard premium for any of these faceting styles. I would imagine the cut with the most light return would be more desirable and in turn demand a bit of a premium over the other two. I have a feeling though that they are all just lumped together as a cushion cut and based off the rap.

And you would be wrong. :D
"Most desirable" is in the eye of the beholder, and there is a trade-off between light return and "fire."
That is the basic reason the GIA believes there is no "ideal cut" and has broadened the concept of "best cut" to include more stones in the "top" cut category so the profit of cutters could be increased.
The "ideal cut" is a philosophical concept and the degree perfection in meeting that "ideal" is a measurement of the craftsmanship of the cutter. If a stone meets that standard, it cannot be anything but beautiful by anyone's standard.

I did not choose my words very carefully i meant cutting(faceting) style rather then the quality of the cut. I agree the cut itself is a compromise between light return and fire and everyone has their own preference when it comes to this. GIAs old system did leave out many beautiful stones that did not fall into the "ideal" range no doubt.

So we have 3 stones all the "same" except they all differ in their faceting style. I would presume the faceting style with the best performance would demand a higher price per carat. I do not think this is the case though.
Sorry for the confusion(i fixed the url link also).
