yeah i also read it with a laughing and with a crying eye :-)
Actually if we are all honest, we all woudnt need more then one of those nice stones, and this for over a whole lifespan....

So Abdulmajeed, if you ever used your last exemple to the stage beeing not more usable any more, and you need a new one, hit me back i will equip you for free



.....just joking that youll ever get it used down, not joking on the "for free" issue...

I actually can confirm the "Eschers" Quality, because i also tested a lot of those stones, besides the Quality of labelled Escher Stones i always got the very good edges from yellow greens and light green stones....not ruling out that also dark-blue stones might be very good...
