//Aurora Aqua Suite
This theme requires that you have installed the aurora theme engine AND the murrine engine for the tabs (I don't like the default aurora tabs), although it'll run without it. Aurora can be found here [link]
and here [link]
for those who use Ubuntu. Murrine engine can be installed through synaptic in Ubuntu (just search for murrine).
This is a theme that I've been using for a while now, and I'm content with it so much that I haven't changed themes in a couple of months.
Also, if you like it, be kind enough to favorite it or leave a comment, please. Enjoy!
