Hi PSers, first post here:
Background - I have started looking for an e-ring. I have been checking out the HCA, Sarin, GemAdvisor (etc) scores as I am seeking an absolutely top tier cut diamond. I have been into see Bryan at WhiteFlash here in Houston and seen some lovely examples, I also visited Tiffany''s and have their agent searching their database for suitable geometric parameters (the ones in the store had horrible HCA numbers, 3.9 and worse from memory). Don''t get me started on Tiffany''s, I know I know....
I am looking for a stone that has incredible performance (ie sub 0.6 on the HCA and near perfect lower facet symmetry) and started to wonder, if I am that concerned about squeezing the last drop out of the optical geometry of the stone for light return (ignore BIC/TIC/FIC), should I be MORE concerned than the average punter about color?
A G color stone seems like a great value stone but if I am chasing the absolute BEST in light performance, would I gain I percentage or two if I went up to a F, or or D?
What I am asking is: Just how important is color to light performace. I don''t want subjective answers, I would prefer answers based on optics/physics. My guess is the impurities in a diamond that give it color are also going to attenuate the light spectrum to some degree. If I am the sort of person who wouldn''t buy anything but a <0.6 HCA/H&A (type)/VH3x3 should I only be looking at the colorless range?
Any input appreciated!
Wonderful forum and community here by the way - I learnt an incredible amount in the last few days!
Thanks
Ash
