bumblebee Posted September 14, 2018 Report Share Posted September 14, 2018 Facets are tricky to spot sometimes, especially on this darker one, but when I threw this one on my flatbed scanner, there was no mistaking! Link to comment Share on other sites More sharing options...
Steph Posted September 14, 2018 Report Share Posted September 14, 2018 Fun what we can see in different lights. Are all those diagonal strips in the bottom half indicative of facets, or are we mainly looking at the sudden change in the top half? Link to comment Share on other sites More sharing options...
bumblebee Posted September 14, 2018 Author Report Share Posted September 14, 2018 It's tough to say because there is definitely a reflection effect that happens on the scanner bed. I expected this to be a foolproof way to find facets but other marbles I knew were faceted didn't show up this dramatically so I there are lighting and focus variables that just are too out of control. Not shown here is another marble from the same lot. Under a loupe it does not have any long facet "channels" but I definitely see the occasional flat spot. Makes me wonder whether that means it was left in the polisher longer than normal? Maybe on rougher jobs they had to polish them longer. We need that time machine to go back and ask!
