Trying to identify a speckled granite from a local creek took me three months.

I kept finding these smooth, dark stones with tiny white and pink bits in a stream near my house, but my basic field guide only said 'granite' and I wanted the specific type. After checking library books and asking at the gem and mineral show, a retired teacher finally pointed out the pink was potassium feldspar, making it a common 'pink granite' with biotite mica. Has anyone else spent ages figuring out a simple rock ID?

Ever try a local rockhound group?

Honestly, that sounds like a huge waste of time. Why spend months on a common rock? It's just a piece of granite, not a rare gem. Most people would just enjoy how it looks and move on. Getting that specific doesn't add any real value to finding it. The fun is in the hunt, not the paperwork. You could have spent those months finding dozens of other interesting stones instead.

Three months for a speckled rock? Classic.
