Diamond Shapes & Colors

I am currently looking for an engagement ring and I am torn between the round, oval and cushion cut stones. Do any of these cuts appear bigger than the other? I was once told a one carat cushion will appear bigger than a one carat round and a one carat oval will appear bigger than a one carat cushion. Not sure if this is true or not. Also, regarding color, I was wondering if a J color stone with a medium fluoresence will face up white in a white gold setting.

It's very very difficult to generalise, since "oval" and particularly "cushion" cover a multitude of proportions (from near round or square to highly elongated/rectangular) and cutting styles. Your best bet is to look at size of specific stones; however the brightness of cut will play strange games with the perceived vs. measured size.

 

In general - but it's a highly tentative generalisation - I'd say the order ("larger" to "smaller") is oval - round - cushion.

 

On colour: it depends on the details of the cut. A well cut round or oval will almost definitely show up white, particularly if you don't have an F-graded stone right next to it. A well cut cushion may - depending on how it is cut (large, chunky facets vs. splintery and sparkly "crushed ice" look).

The easy question first--Color. By definition, a J color is in the bottom of the "Near Colorless" category and, as such, should face-up white, no matter what metal you put it in (and of course, white will sometimes "brighten up" the appearance to the beholder). This is, of course, if you have a truly J color stone. You can trust your color if you're talking about a stone that is GIA or AGS certed--maybe a little lower in color if it is EGL (esp International labs) or uncerted.

 

Now for shapes:

 

Ovals and Marquise--because of the way that they are cut, they will always look bigger than their same weight counterparts, because the weight is spread out in a different way. Rule of thumb, so to speak, is that the rounder shapes (round, some cushions) are always going to look bigger than their square/rectangular counterparts (esp, Princess) because the weight gets tied up in those corners that are "cut away" for the rounder ones. BUT, depending on how well the diamonds are cut, a 1ct round and a 1ct square cushion CAN look pretty close in size.

 

Good luck and let us know what you pick! :)

Hi Tata

I have a slightly different take on this.

J color is classified as "Near Colorless"- however certain people are extremely color sensitive, and may notice the tint, no matter the metal it is set in.

So this one comes down to your sensitivity to color in diamonds.

I love J colors, but I can easily see the tint in many cases.

 

In terms of which looks largest, it's a case by case basis.

Some marquises look huge for their weight, others not so much.

Cushions and ovals can take so many forms- when the LxW is different.

Then we have to consider the depth.

As opposed to rounds, where the parameters are much tighter- a well cut, yet shallow round is 58%, a deep one can be well cut at up to 62%.

Nicely cut ovals and cushions can range from 50% up to the high 70's- and even greater. Therefore the range of visual sizes for a one carat cushion or oval is far greater than those of a round.

Generalizations simply don't work in this aspect

I just want to add a few facts about cushion cut engagement rings. Cushion cut diamonds are different then other diamond cut (60 facets vs. 80 facets) - For that reason the diamond light reflection appears different (more romantic). This design is more for woman who like antique designs. There is also this site which has lots of important info concerning cushion cut engagement rings.
