I may be out-of-date, but I believe you can make gems through the jeweler for roughly the same price that they sell on the AH. The AH gems just allow you to skip that step.
Sooooo, you COULD blow all your gold on gems now, or wait and see if the jeweler is getting any improvements in the xpack.
While true, the time it takes to make the high level gems should really be reduced.
The time needed now is just unbearable. The change that allowed us to make several items in succession with one click helped a lot, but it is still a lot of standing around waiting and waiting
