Pete, thanks for all the inputs. I was in touch with Steve (prof's AR look impressive imho) clearing out a handful of doubts I had before shipping him the crystal, but for some reason haven't heard from him afterwards. Regarding the PR I actually did move it, just left a couple mm as I wasn't able to tell if gen really goes all the way to the end of the marker Also, it's really a good idea to put them reps on another wrist, will try that! EU might be an option, but the "water droplet" thing got my attention I mean, it's supposed to be sapphire but I wouldn't be surprised if not. Do you mind elaborating a bit more on that water droplet test and results? Sent from my iPad using Tapatalk ------ Just found out that the water will 'concentrate' like small ball if sapphire. If mineral crystal, water will 'flat' like 'spoiled egg'... Will try that
