HCA vs. BrillianceScope

VampireX02 Rough Rock Total Posts: 25 Last Post: 3/22/2002 Member Since: 2/26/2002	I just saw something else that I thought was interest. The BrillianceScope report. Which looks like little sliders from a computer program (probably a screen shot). It included everything the HCA has except spread. How does the HCA compare to the BrillianceScope. Is it the same basic idea? What I most liked about the BrillianceScope is that it was a graphic representation of where in the "very good" range the dispersion fell for instance. When you run the HCA..you might get "Good", "Very Good", "Excellent", etc as a result for each of the 4 elements and then a final numberical rating for the overall stone. Is there a way to get the breakdown of that number? Like where each of the 4 element rate individually as numerical data instead of words? Would be really awesome.

The HCA is way more portable as it is a "Predictor" of the light performance. You don't have to have the stone physically to use the HCA for the result. Likely as not, they both would give similar end products. One is a large device and costs a lot of money. One is a program and can be run for no cost, not even shipping expense. I suppose one might develop a preference for one of these over the other. I could understand why. David S. Atlas GG(GIA), ASG, Sr. Mbr. NAJA www.datlas.com
