Hey everybody!
Sometimes when someone's considering a purchase, they ask us to photograph two different items next to each other to gain perspective.
Today someone asked for a picture of two Asscher cut diamonds, next to each other






The diamond on the left

The diamond on the right


Rather than making any comment myself, I'm interested to know what people's thoughts are!

The diamond on the left looks more yellow than the diamond on the right.  Even though they are graded very close in color, the one on the right has medium blue flourescence.  Also, although I could be wrong, the diamond on the left looks like it has a culet.  Is that right?  Either way, the bottom of each pavilion looks very different on the two.  The symmetry on the left diamond seems better than the one on the right.  The diamond on the left has a four-step top.  I can't really tell how many step-cuts are on the other diamond but I would guess three.  The one on the right has better clarity, but I got that right off of DBL's web site.

Okay, I'm stumped.  I would say the color on the right diamond looks better to me because of the flouresence, but poorer because of the symmetry.

 Huh? Mikla

I like the cut on the diamond on the right better, but the one on the right obviously faces up much larger and whiter.

(Have I mentioned lately how much I love my DBL Asscher?  I get so many compliments on that ring....)

The one on the left looks more like a branded one, but I like both just the same...and unless it was my man wanting to see them side by side, I will have to say that I like both.

 Both have nice cuts but assuming they do have the same 4c's the one on the right should have fluorescence to appear that better. The one of the left has a nicer cut too. Strangely I see more color light on the left stone. I guess every diamond really has their own unique beauty.

I love the one on the left - it looks to be returning more light and I like the overall shape and facet pattern better.  But don't get me wrong, they are both beautiful stones!

Well, I  do have my favorite of the two.  But, I am most surprised and interested at the difference in the pavillion shape. Really interesting.

I much prefer the little guy on the left. His overall size and pattern appeal to me. I like his warmth, too. Sweet little stone. What are you planning for him?

The one on the left has a nicer cut (slightly marred by imperfect simmetry - but you'd never notice it once it's set, and the other is also a bit off).

The one on the right has a steeper pavilion cut as well as lower depth ratio (for the mathematically inclined, I'll point out that the side of the R diamond is a whole 6% longer than it would be if a stone of the same weight had been cut as the L diamond). Oh heck - it faces up a lot bigger.

The one on the right also looks whiter (whether through flourescence or simply the angle of reflected light in the face down shot), however, being a man and thus with a less subtle chromatic sense than most women, I'm not a big fan of either shade.

If I had to buy one, I'd go for L. The cut is just nicer. And it's 15% less per carat.

Hi everybody!
Thank you everyone for your responses.  One thing I've learned, there is no right answer.


There have been cases where a client is choosing between two diamonds, and picks the one I prefer less.

This has resulted in some beutiful rings that I would never had made, if my initial taste was the barometer......


Another example of "frist blush": sometimes when presented with a group of diamonds.  I select one, and reject the rest,  because one stands out at that moment.
Sometimes, when I look at the remaining stones later on, I see a few that I end up liking as much if not more than the first one I picked.



OMC- what's the deficit in symmetry you notice?
I have not noticed any asymmetrical facets.

I thought I saw slightly less than perfect symmetry at first too, but when I looked closer, I think they were just slightly tilted.

I love the smaller stone, very much. Which was your first choice David?

The one on the right looks like it has a shorter angled corner - top left.

Also, why are the pavilions so different-looking?

And I just re-read my own post, a post which demonstrates that I do not know my left reliably from my right.

What I MEANT to say was that I prefer the cut on the stone on the left, but the size of the other.

Or something.

So what Robin is saying, is that she needs David to get in about a 5 ct. asscher.  Didn't you just say that Robin?   Wink

I have not noticed any asymmetrical facets.

I may be totally wrong - assessing 3D symmetry from a 2D photo ain't easy, and given magnification even small "out of true" in the diamond or the camera angles come out as big differences on the screen.

The L diamond has - to my 2D eye - two shorter corner facets (top left and bottom right). It is symmetrical, just not perfectly (the "windmill" has two bigger and two smaller sails).

The R diamond has the pavillion facets on the right side a little larger than those on the left - this is visible in the much larger scale pics on the DBL site; there is too much difference in the photos on this thread, which are clearly due to out-of-true angles. Again - a tiny difference of angle could make me see things which aren't there on the DBL site (and I am not a GG, BTW)

To summarise: 1. you'd never see either even with a 10x loupe. Only way to see it is in 25x microscopy/macro photos; 2. I'm not sure it's there given the 2D-3D affair; 3. I'm oh-so-grateful to GIA for their reports; this is blipping difficult to do!

Gorgeous stones D!

I love them both and would have a tough time choosing for myself.

The one on the right seems to have a cut more similar to the center stone in my 3 stone asscher ring and the one on the left seems more similar to my sides---both look gorgeous set Smiley

Good luck to the client looking at them!!!

Hi! Just jumping on briefly as a lone voice here. I love the one on the right and had just been admiring it the other day. I much prefer the size and color on her. So, I guess I can have her since everyone else is tossing her off, right?

OK, this is bugging me.  If I have this correct: the diamond on the left is an O-P.  The diamond on the right came in reportedly as a K color, then, David deemed it to be M color. But, when I look at the pavillion shot, there are sections of the diamond on the right that, to me, look even more tinted than the OP on the left.  Now, I realize that it is difficult to tell from a photo, and also, I realize that one must judge the body color that is most prevalent... but, could it be that the diamond on the right is actually still lower in color but faces up whiter?

Oh, gosh.  I can't stand this anymore... please put me out of my misery! SEND THEM TO GIA!

The diamonds are both going to get GIA reports.


We weren't going to but when Trinkette uses such a large font, we get the message ( don;t want to upset Trinkette now, do we....heheheh)

Of course I'd never say you're...wrong ....but let's see what GIA has to say!
