HCA Discrepancies?

[dugout41]

I''ve been looking for various tools on the web to assess a diamond i''ve recently purchased and have found two different HCA calculations for the same measurements.

Has anyone else experienced this?

I was using the HCA calc from the following sites:

http://www.ideal-scope.com/hca.asp

https://www.pricescope.com/cutadviser.asp

my measurements were:
Depth 61.7
Table 54
Crown angle 35.1
Pavillion angle 40.8
Cutlet 0

On the pricescope it rec''d a 1.8
on the ideal-scope it rec''d a 2.1

Is this just due to different versions? which one is the most recent software?

can anyone run a diamond calc for me? shelling out the $300 for the software is a lot.

if you want i''ll pay for a one-time run via paypal.....

intersesting. i don''t have the answer to your question, but i''m sure garry will be here to clear up any confusion.
what answers are you looking for in diamcalc?

Thank you, Dugout41. Ideal-scope version seems a bit outdated. I''m going to check it out.

answers in diamond calc? nothing specific, just looking to assuage my anxiety.

i haven''t rec''d my diamond yet, i will next week. the ideal scope pic was a little out of focus but the dealer had assured me that i will love it. i thought the diamond calc would assure me of the symmetry despite the ags000.

i guess i''m becoming somewhat obsessive.

funny since i won''t even be the one wearing it, and a month a go i didn''t even the know the differences in shapes/colors, ect...

diamcalc cant help with the optical symmetry because without a 3d sarin or helium scan it is just guessing at the symmetry and minor facet construction.
Post the IS image and we will see if we can tell anything from it.

Deep breaths. Focus on the prize. If this is the GOG stone, and Jonathan said you will love it, guess what, you will love it. Repeat after me, I must relax. My first superideal purchase had a Sarin and a OGI megascope. The numbers were a little dif., but not by much. One yielded a .9 on the HCA, and one yielded a 1. My diamond looked the same either way.

You will get through this FUD (fear, uncertainty, doubt). We will help. When you see it, you will wonder why you were so worried.

Fixed HCA for Ideal-scope.com; found a tiny bug

Storm is right, Diamcalc only produced simulations for the data you enter there and average Sarin numbers might not describe the real stone accurately enough.

Your numbers look good so far, no reason to be anxious

thank you all for your words of encouragement and advise.

i just have to wait and relax.....

i just hope she loves it, that''s what really matters. i have to quit anticipating the show-n-tell moments at the office or with her friends...

thanks again.

Yes Dougout, it should be a very nice stone, as long as the upper girdle facets have not been dug out

ha ha he he

thx leonid for fixing the glitch
