Cultural Smithing Costs

[firesyde424]

I just hit 170 smithing and I was looking at Ornate for further skill ups. I also took a look at High Elf cultural smithing and was shocked.

For just the enchanted BP and Legs, I need 20 blue diamonds to enchant enough mithril. Assuming I wanted the entire set, I'd need 85 blue diamonds. Last I saw, blue diamonds were selling for 2-3K each. That's a phenomenal amount of money. If what I'm seeing is true, I'm guessing there's no point further increasing my smithing skill?
