Skeleton Sniper Gem Won't Upgrade

I have now leveled up to 90 and didn't realize that my skeleton sniper gem is not showing up to allow it to be upgraded!

So I have level 2 skeleton snipers and level 19 for everything else (storm mage, cleric etc.)!

Worse, I've traded for socket upgrade gems for it and it now has 5 sockets but is at the lowest level of gem!?!?!?!

Any thoughts on how to upgrade the gem, I obviously don't want to loose my sockets.

I think I have the same issue...
The gem does not appear in the equipped gems list when you try to upgrade it!

I noticed that if I cut a new gem of lower than max level and equip it, when I try to upgrade it again, it would let me. Thus, I suspect the bug has something to do with gem quality or number of sockets.

I noticed that my level 15 20% quality blasphemy gem doesn't appear either in the upgradable gems... I am starting to think that it's due to gem quality...
Can you guys in the thread confirm this? Are your non-upgradable gems of 20 % quality?

My problem is that the Prism of Belief Diamond has no effect
