How do I list an unidentified unique Jewel?

Hey everybody,

Just want to ask everyone, how do I post a trade of an unidentified unique Jewel in the trade section?
The picture of the unidentified unique Jewel is as shown above.

I asked this question because when i type Rainbow Facet, it will list down either cold Death or cold level-up.

I guess my 2nd question is , does everyone actually sells unidentified unique Jewels in the first place?

Title: Jewel
Message: Unid #COLOR# Rainbow Facet (fire, lightning, cold or poison ; death or level-up)

Rarity: Unique
Qualities: Unidentified
Item Type: Jewel

Before you do that though, can I make a case for identifying the facet?

Finding a facet is a bit like buying a lottery ticket. Not one of those huge million dollar jackpots, but more like one of those crappy small town raffles, where the main price is a Volkswagon Beetle, that you suspect might have had a previous owner.
But you do it because... heck, its for a good cause and a free car is free car.
But then you sell your unopened lottery ticket, because you are missing a dollar for one of those overpriced, tiny amusement park beers. Why?

Moral of the story is: Don't sell an unidentified facet. You'll get scraps for it and you deprive yourself of the fun of seeing if it is a dud, or the jackpot. (It's probably a dud)
