🔎 UNIDENTIFIED Please help me identify these rocks found in an antique stone wall in CT in a spot where Native Americans and Colonists resided.

I found these three stones in my friends’ stone wall (along with a unique item posted in another thread). It’s in CT. One of the stones is a perfect rectangle. Any help would be appreciated! One of the rocks has veins sticking out of it. There are three stones, I posted front and back of each. The last appears to have a light blue paint on the flip side.

I can’t tell much from the photos. They look to have some hematite mixed into their structure. How hard are they? Can you scratch them with the point of a steel pocketknife?
I’m not seeing the perfect rectangle.
Thanks for posting.👍🏼

The whiteish veins are probably quartz, and the darker material is obviously softer, but no idea.
