I'd take some out of Critical Hit and put it into Orange mastery.

Orange Gems are very useful - think about it a little...a single orange gem in a trap will provide supplemental mana and pay itself back easily.  The single, weak mana gem in a trap will bring you enough mana to pay itself back over 3 rounds or even less.  This is very good for supplementing your mana gain...

Well, sorry about the double post, but it's been a day, and I have more pictures to update:

Wave 21 - Skip all others if you're in a rush...  This one has a huge score jump from 20.

wowow... This is madness :S

One person scored 13 Trillion before (and it would have been more), and if my computer is stable, I'll break that by a huge margin.

I'll be in the Trillions by the 30s, and I'm still getting "warmed up" - you don't start REALLY scoring until after wave 54, and you peak around 90.

@Einfach: Could you post one of your saves-stats where you collect all of the lost gemstones? I'm on the 4 island and I only looked in normal mode under the stones... according to your last post the occurence of the amulets is also mode dependent.
Amulets are only under destroyable items?

@Peterfarge

I have not collected all of the lost amulets.

Amulets are only under destroyable items, so this can be beacons, stones, or buildings (I think...).

This should help: http://www.gemcraftguide.com/Amulet_Guide.htm

The above link is to a spreadsheet which has all the lost amulets.  So don't look at it if you want to find them yourself (It's much cooler finding them yourself, anyway). :)

Einfach: Thanks for the link :)

OK - an update on the game for you all.

Higher scores coming soon...Notice that the score is increasing faster and faster.

I apologize, but the link above is faulty.  Here is the real URL (copy and paste it into the address bar.
