help me pick a stone

[rebeccarose]

Based on your feedback from last time I went back to my jeweler to look at different stones. I think we have nailed it down to these two. Which one do you guys like better overall? My boyfriend thinks the E looks nicer colorwise but I like the cut/fire in the F more. What would you pick? They are both around the same price. Thanks so much for all of your help!

diamond 1 at first glance but the hca dont like it
back in a few...

 

[Kaleigh]

#1 looks like a winner to me!!! HCA doesn't like it??

 

[strmrdr]

on further review neither.
But I dont think the first is as bad as the hca makes it out to be.

hmmm this is strange.....

 

[rebeccarose]

Sorry I''m new at this what is the HCA and why don''t you like either?

 

[strmrdr]

There is some leakage under the table but its very bright and contrast is good.
Should be a nice diamond but the hca hates it.
hmmmmm
Garry needs to weigh in on this one.

Yeah, this just doesn''t make sense. Those look like good opposing angles. shallow crown with deeper pavillion should be a nice bright diamond, right, strm? what''s going on?

The second is deeper than I like.

The first the 2 tools I use most are giving conflicting results.

the hca is here:

#1 looks better than #2. Hope Garry chimes in about the HCA.

 

[rebeccarose]

I''m so confused I went to the HCA and plugged in the numbers and it said it is 1.5 and excellent? Excellent doesn''t sound like hate to me? Am I reading something wrong?

 

[strmrdr]

Selected: 61.4% depth, 55.3% table, 33.8° crown angle, 41.4° pavilion angle
The result is for a symmetrical diamond with a medium girdle and very good polish
HCA scores were adjusted Dec. 15, 2001 and Feb. 6, 2003.


Factor Grade
Light Return Good
Fire Good
Scintillation Good
Spread
or diameter for weight Very Good
Total Visual Performance 4.2 - Good - Only if price is your main criterion

Wait for Garry to weigh in on this one.

Looks like Garry isnt going to comment,
My advise is trust your eyes.
Stone 1 should be bright and if it looks great to you under different lighting conditions then it is good to go.
If the hca score was the truth on it you would know it because it would be yucky.
Id pass on stone 2 its too deep and you said it wasnt that fiery.

Thanks so much for all of your help, I really appreciate it!

Sorry I couldnt be more clear on it and for the confusion.
Is weird when the tools disagree it dont happen often.

sorry
flat out like a lizard drinking

I am going to adjust HCA for stereo scopic rather than myopic vision
this will seemingly make some scores like HCA 3.5 - 4 closer to 2.5.

I am still not impressed with this stone on this tiny bit of data - but if the data is out a teeny bit, or the stone is painted - especiallyt in the pavilion - then it could be great.

Get an ideal-scope - or if you are far from the stone - an image if you can.
If they say they cant then direct them here for very simple instructions http://www.ideal-scope.com/newsletters_issue008.asp
if they refuse then find another vendor?

What is "stereo scopic" vision? And when do you expect the changes in the HCA to happen?
