Ok guys... I guess this is a rather rare opportunity so we don’t see much of this comparison on the internet. But I got a hold of a early production 2007 sapphire sandwich 3573.50, and compared it with my current production 2017 sapphire sandwich 311...006. The difference is shocking.
The shape of the crystal is significantly different, resulting the 2017 one having a evident “milking ring”, while the 2007 one looks almost like a hesalite crystal... I don’t think I need to tell you which one is which in the picture... stunning
I don’t know what to make out of that.. I can compare it later with my hesalite, to be continued...
