help me find this clasp/finding!

[iamdolleyez.livejournal.com]

I just recently became interested in jewelry making, and actually started picking up a few supplies (i'll take pics soon)
i want to make a necklace with multiple strands, similar to the one in the pic..but i can't seem to find a clasp like it?
I checked at firemountaingems and either i am blind, or they don't have it. anyone know? online is fine, offline, well i'm in toronto, ontario (canada. hah hah)...i havent' seen anything at arton (for those toronto folks) but perhaps i was overwhelmed by the sheer quantity of stuff there.
here is a pic of what i'm looking for..(and a lovely necklace as well)



and so its not questions only....


its just a hobo bag. but i'm proud of it! i managed to line it properly, and the sewing is straight....not wonky as per my usual attempt at purses.
