I guess I hadn't been paying attention. Someone earlier said that perfect squares went for more than they cost to craft. I took that to mean that the crafting price was reasonable for some reason, when that clearly isn't the case.
30k a pop to craft (plus mats). How much do these sell for?
Hard to say since consumable AH is down. But here's some simple math.
1 PS - 3 FS + 30k
1 RS - 3 PS + 50k = 3*(3 FS + 30k) + 50k = 9FS + 140k
1 St (Star) = 3 RS + 80k = 3*(9FS + 140k) + 80k = 27FS + 500k
1 FSt = 3 St + 120k (?) = 3 * (27FS + 500k) + 120k = 81FS + 1.62m
So 81 flawless squares and 1.62m just to craft a Flawless Star, assuming of course you have the recipe.
You can see where this is going. By the time you get to radiant star I expect it's roughly 15 million and over 700 flawless gems just to craft 1.
there is absolutely no reason to sell any of these gems cheaper than cost to make on the AH, because you HAVE to make them. The reason the other gems sell cheaper is because you can find them on the ground in Hell and Inferno.
If anything the later gems will be more expensive on the AH, because it's saving you the hassle of collecting materials.
