Would it be possible to have a table of the different gems and their stats either in the in-game book or on the Wiki here? It would be useful for comparison and planning which gems to use. I had thought about manually transcribing the data, but I thought that it would be faster for you to dump the data directly.

Will do. For now, you could view them in this source file: EnumGem.java. Hopefully my abbreviations make sense.
