when i did the gold road ingots were about 700k a stack, there was loss (not including breaks) but they sold fast. Right now i think gold ingots are well over 1m a stack, you would just need to figure out how much loss their is from ingots to rings/earrings.
GS is allll about having millions of gil tied up in materials >.> thats why i kinda stopped at 57.* (+1 ^-^
