Very nice. The shiny effect is well done.

It's the green that makes this stand out from the rest!

Thanks a lot everyone!

excellent, really nice colors 

Brilliant piece of work, this one.

Good shades

Great work done there.

Highlights are beautiful on this.  Really really like the center gem.

Nice, looks like it would make a nice jewelry.

Nice, very sharp and real looking

Nicely done!

Glad you did, that thing looks killer!

not sure what you mean, but glad you like it! There is, or atleast should be only one light source on the top left.Or do you mean the "backlight"? 

Love the difference sources of highlights :)

Nice! I like the choice of color... Except the green. I'm not sure why but it sort of bugs me. But that's just my opinion :) It looks great!
