So it''s safer to have pavilion angles in a tighter range than looser one, but if not, as long as the opposite pairs of facets are matched, we''re apparently looking ok again.


Maybe in Tolkowsky''s 2 dimensional world, but in 3 dimensions, only a fraction of the light might hit a facet straight on enough to be reflected to the opposite facet. Most, if not all pav. facets (even the neighboring ones) will receive the bounced rays in diffuse light, and in direct light, the diamond''s orientation will determine (and to a lesser degree the facets'' azimuths) which determine which facet gets the bounce.

Any comments?
