My experience with the pink Ali has been regularly dropping 4-6 gems. Sometimes 8 gems. Rarely 10 gems. And ultra ultra rare drops of 50 or 100 gems. I think I may have gotten 100 gems once and not sure about 50 gems. So if you are considering a purchase you will be doing so for its beauty and "I just have to have that!" Lol
But, maybe your Ali will be more generous than mine. I do love having it though.
