I'd trading t2 and t3 gems, and runes, and eq for t2 and t3 gems.
For one of these gems:
Blue Star Sapphire
you can get one of these gems or items:
Fist of the Lord of Beasts
a spider-shaped ring -0.3 +hand dam
a thin silver circlet, +10ma +max int head
a ring of seashell -0.1 +2hit +2hp regen
a mithril keychain (contains 45 weight)
the keychain of the shuggoth lord (contains 45 weight)
For one of these t3s:
a Tomb Jade
you can get one of these:
a Light Blue Iolite  + any of the t2 gems or items above
a Gray White Diamond  + any of the t2 gems or items above
a bracer of emerald flame, -0.1 -2saves +hit
armplates of the lion-hearted -0.8 +weapon dam +5hp
a lost-cross signet ring 
If you need other eq* and would like to make a trade, let me know, and I'll pop it.
* a few exceptions apply.
Talk to Taron ingame or mudmail to make a trade to get what you want.
