Yes, I'm aware of that. However, gems above flawless square can only be crafted by players, and to craft a perfect square costs 30,000g + 3 tomes of secrets + 3 flawless square gems, which totals to about 60,000g just to make the gem. Then, to account for the 15% transaction fee at the AH, the gem has to sell for at least 71,000g just to break even. It's hardly worth the ridiculously expensive setup fee for the artisian crafting skill, as I can make more than the profit margin by just grinding for 15 minutes.
