Could you ladies give me some advice in regards to what to look for in a cushion cut diamond? There are a lot of variances with cut, shape etc... and I would like to know what I should be looking for, i.e which characteristics would be more important, clarity, color etc... Any info would be greatly appreciated!
 
Cushions cannot be judged by numbers and color alone. Not color, clarity or demensions you need to look for a good cut diamond. Cut is king, not size, or any other characters effect the diamonds brilliance then cut.
I did research for over a year to find my perfect cushion.
you also need aset image on the diamond which shows you how well the light is reflected by the cut of the diamond.
Go to pricescope.com for lots of helpful threads on cushion diamond and samples of asets and well cut diamonds.

Thanks LucyDee! I agree, cut is king when it comes to cushions and I think I found the perfect one (I think). I've started a new thread so I would really appreciate your comments there :)
 
The ASET is a device developed by the AGS lab to help gauge cut grade and light return. An ideal ASET image will have a lot of red, some blue, and minimal green and hopefully little or no white, as white indicates "leakage" through the stone vs light return back to the eye. The distribution of those colors is important, because it indicates the way the light is reflected by the stone's facets. Many of the reputable online vendors, like Good Old Gold, Brian Gavin Diamonds, High Performance Diamonds, Whiteflash, James Allen to name a few, offer images photographed through the ASET scope of the stones they sell to show the light return and cut quality of their available stones. Blue Nile is one that does NOT use an ASET or IdealScope, another light return type scope tool. It's used now on a lot of shapes, but primarily was used on round brilliant stones to grade cut quality.

Here's a PDF from the AGS on the ASET tool to give an explanation on how it works.

I have questions on diamonds that are much smaller. I am talking .25 ctw. Does the cut matter that much? The stone I am interested in has an ideal cut, but is roughly $150 dollars more than a stone which has a good cut.

I am asking because I am interested in buying a pair of .50 ctw diamond studs.
 
Yes. Cut always matters because cut is why a diamond sparkles. Depending who the vendor is, getting any information (assuming they have it) on a stone that size or smaller is difficult. If they don't cut their own melee (small diamonds) they won't have the info on the stone's cut quality.
