When you bury gems in the underground if you bury a size 3 pale and a size 5 pale when you bury them they won't always be size 8, and if you have alot of green gems ect. and you bury all of them you will get a size of 99. this is the biggest size, but! dont bury anymore than you need to cuz if you buy soemthing thats 8 pales and you got 99 of em' you will give the size 99 gem for a small 8 gem item so, only bury enough that you need dont bury any more than you need, cuz ur just wasting all ur time! RATE PLEASE if you go thumbs down your a freaking LOSER!!! so go thumbs up =P
