AR Coating

[ShiroTenshi]

That will be interesting to know how they iron that out, educating about AR at the same time.
Is the PAM111 suppose to be single or double sided AR anyway?

I mean did irod talk to the dealer and figure out what happened.

Yes, I did. The dealer agreed to exchange PAM219 to new piece. My shipping expenses is about $75
I asked the dealer for alternative way - just send me new crystal at my expenses(no answer yet).

I did "water test" for crystals - on PAM112 water drops looks this way on both sides of the crystal:

So most likely double side AR coating presents.

On PAM219 I did the test for outer side only (because I didn't decide yet if I should ship it back to dealer or not ):
