Almost 400
BTC invested and no one willing to buy more even lower then ICO. That's not a good sign!

Price will rise when people actually start using JWL often in game.
The game should only use JWL ^^
How do I sell my things for JWL ? On the auction house ? ( if there is one ) I have asked someone this before but it got lost in the thread.
The auction house is something that will be released in the coming months. None exists originally.
If you wanted to trade with jewels currently you turn them into ingame items (such as vip tokens or garments) to trade with other players. We're also looking at doing a tradable 'jewels token' which when used re-grants the purchase cost to the person who used it (that way you can sell an item for say 1000 jewels and that person can then use those jewels on whatever they wish.)
