Welcome to Gaia! ::

You guys can also donate gold!

I don't really know how much help your expecting.
the Angelic Halo isn't more than a Dream to those of us who weren't around since at least early 2004.
You could try swapping to the Platinum Halo or the Prism Halo. They aren't as beautiful, but they're equally efficient in giving the illusion until the actual item is obtained.

I should mention, the Angelic Halo is actually worth more then Tektek thinks it's worth.
Grizzly Hat + Chicky Slippers + Portable Headphones + Bunny Slippers + Mini Angel Wings + Devils Tail + Angelic Sash is approximately the worth of the Angelic Halo.
175,000,000 (Grizzly Hat) 50,000,000 (Portable Stereo Headphones) 35,000,000 (Mini Angel Wings) 24,181,818 (Devil's Tail) 17,558,334 (Angelic Sash) 60,000,000 (Bunny Slippers) 35,000,000 (Chicky Slippers)
Which totals to 396,740,152 gold as the current bid in a thread that I'm watching. (if your interested in looking at the thread as well, you can click here)

I need donations for enchanted book and biancamella.

You should just try for the newest generation of your evolving items, it tends to be cheaper.
So, for example.
a 9th gen enchanted book, won't have the poses, but it's the most inexpensive and will get the poses at a later date.
as for the Biancamella, the sixth gen is the cheapest, and it's already got all of the forms unlocked.
