On the AH it seems like the cost to buy some of the gems outright is cheaper than it is to combine 3 lesser gems, but I don't have any to check. How much does it cost (in gold and materials) to combine gems between each quality level?
In case you were interested in the cumulative costs:
Rather than starting with a Chipped gem, here are cumulative costs starting with Flawless Squares (the highest rank gem that drops):
I've listed all of the costs below. Remember, that this is the cost in addition to the gems of the previous level.
The recipes below require 2 gems of the previous level
The gems below do not drop and must be crafted using 3 gems of the previous level
Thankfully, Gems in Diablo III are reusable, so you won't have to recreate Rank 14 gems every time you get a new socketed upgrade.
