It's 15mill+ on Fairy now. As far as I'm aware, only Dhalia and Ogu craft them. It's a nice piece of gear, but it's not a neccessity, and it's not worth that kind of price. I have two, which I've had for quite a while, and as much as I love them, I'd warn everyone to stay clear of them at their current price.
This earring sells for 4,000,000 G on Seraph. Nasan is the only seller on the list, let alone Bid History only shows 5 ever been sold, 2 of which I have. Q=('.'Q)
