pebbles

I believe what I have here is a pictish pebble made from quartz. There have been 19 similar stones found in the last 90 years and I believe all of them have been found in Europe. This one was found last year in the northeast United States. The picture with the multiple stones is from Painted...

I have found these in the beach sand. From that day on no one is able to help me identify these. In these pictures the stones are 100% dry.
