I ran across these interesting views of a round brilliant and Gabrielle diamond taken through what looks like a variant of the standard Hearts and Arrows viewer and thought Pricescope readers might be interested. Below is a round brilliant.

Very very interesting D. Observing the images of the 2 stones reminds me how certain diamonds may register as having "x" amount of light return but how those facets are arranged can greatly differ the manner or nature in which the light is being returned to the observer, giving 2 completely different looks while perhaps having very similar photospectrometer readings. This is the case with the new Eighternity diamonds we recently started carrying. They score incredibly on the B'scope but the way they reflect back that brilliance to the observer is quite different than a traditional H&A. Rhino |

Though you know how little stock I place in the BrillianceScope, I don't doubt that what you're saying is correct. To illustrate what Jonathan is talking about while keeping on topic, below is the "arrows" image of an Eighternity diamond from his site.  D Riley |

Date: 8/13/2004 8:33:12 PM Author: Rhino Very very interesting D.

I don't believe the B'scope is a useful tool for determinations about beauty, but I think what you're saying is valid, and pertinent to comments occuring in portions of this thread discussing new GIA cut grading. When 2 stones appear equally beautiful (or receive similar readings on the hated B'Scope)  I feel the configuration of oft-overlooked minor facets within given sets of our accepted (tight) large proportions is key to defining the character of that beauty.

Amen to that Sir John. Nice wording there too... "character of that beauty".

Given what's been said above, how much stock do you put in this discussion of minor facets? http://www.gia.edu/gemsandgemology/620/19519/this_weeks_news_details.cfm

Date: 1/13/2005 4:55:31 PM Author: Rhino Amen to that Sir John. Nice wording there too... 'character of that beauty'. Thanks good Sir Knight.  I use that term in discussions to differentiate between aspects we've discussed (balance of WLR/DCLR, etc) after tools and toys are at an impasse and human preference must make the final evaluation.

Actually, that article has been discussed previously here on PriceScope. It's more about leaning facets, indexing in colored stones and girdle strategies/adjustments than the "minor facet" details Jonathan and I allude to, but still an interesting read. My friendly neighborhood cutter has told me that inaccuracies are rife throughout that article (it's a cutter thing), so absorb it in at your techno-peril. If you're interested in that pipeline of intrigue, a follow-up may be this thread on what Brian Gavin has termed facet yaw. It is of remote interest to most - mainly pertinent to cutters, scientists and fans of extremely true patterning...It is also still in-progress. John |

Woof! "Actually, that article has been discussed previously here on PriceScope. It's more about leaning facets, indexing in colored stones and girdle strategies/adjustments than the "minor facet" details Jonathan and I allude to, but still an interesting read. " Sorry, I missed that in searching. Thanks for pointing it out! I vaguely remember having seen it before, but not when I was on this particular trail. I am just trying understand what influence the details of cut do or do not play in performance. This is a real peeling-the-onion experience, just when I think I understand something, there's a whole newer and more complicated level to consider. But that thread adds a few more clues. My apologies for the distraction.......

No apology neccessary...All of these musings pertain to details of cut. Anyway, to distract me & Rhino you'd have to post pix of a white beach, palm trees and tiki torches - then throw us a frisbee. John |
