I was given the following information from an informed fellow pser for searching for a great emerald cut diamond: "make sure the depth of the stone is larger than the table"

apparently, if i head this advice i will have a more brilliant stone than if i don''t.

can someone second that...
 
Smaller table is good but the depth can vary a lot and still look great.
But i can see where they are coming from.
in general the best will have have some depth and the smaller tables.
 
thanks storm

can you plug some numbers in so i have a better idea. when you say a small table what range does that refer to?
 
Great question, is there a general rule of thumb to go by?? or a chart you could post??
 
My opinion, I would follow Dave Atlas'' chart for ECs.
 
great minds think alike

That is the exact chart that i have been using to guide my search. but a lot of stones i found within the parameters of the chart do not fit the smaller table than depth advice. the chart numbers are what also led me to question this advice, because if you look at the 1B range the Depth stays the same, but the Table expands in range, so that the depth will be smaller and not larger than the table. (that was a complicated thought)
 
I trust that chart quite a bit. I used it when I purchased my fancy cut, only choosing to look at diamonds that fit in the range I found acceptable. I know with fancies there can be some real beauties with bad numbers but I felt that my chances were better by following the chart.
 
I was given the same advice when purchasing my EC so Id love to hear the scientific explanations from Dave, Garry, Jonathan, Ana etc
 
bump-waiting for ana, dave...........
 
lulu...I think that while numbers don;t tell the story with fancies, if you are selecting totally at random off of the net, then selecting a stone with a depth greater than table may help you find a stone with good crown height and a good crown/pavillion balance?....if you have a stone with a very large table compared to its depth (or maybe regardless of its depth for that matter?0, that may be a recipe for a physically flat stone...aka lifeless stone...the experts can give a better explanation I'm sure

I respect the theory and intention behind the chart, however I disagree with some of the characterizations.

As far as table smaller than depth- balderdash, in my opinion. Rules like that really do not assist in picking a great stone.

I''m sure my opinion will be real popular....hehehe. Serioulsy, a lot of folks would love to believe you can buy a diamond using a chart- I disagree.
 
I think a chart is helpful as a guideline, but what is most important is your eyes. People always want to go by numbers, but at some point you really need to trust your eyes, especially in fancy cuts. So David I agree with you there.
