sink

I noticed your posting below and I too have a similar granite counter and am searching for a black sink.  I'm fine with most any material, including granite composite or even black cast iron.  However, I'm having trouble locating a sink that will fit in the pre-cut granite hole.  The sink I need must be 31.5 Wide by 20.75 Deep (front to back) to fit into the current hole.  I'm interested in knowing how the query below was answered and also if you can point me toward any source where I can find a sink.

Thanks!
