Hi Tony welcome to the forum!
we've got similar interests.
Here's some of my Amble Agate, ok not too fantastic, but I'll keep looking. (Took me weeks to polish it) And a piece of the Acklington Dyke* sawn and half polished by me, but as you probably know the composition of this rock makes it hard to polish.
*Our youngest local rock at a mere 58 million years old. Also see Buddle's map on the Acklington Colliery page. Still amazes me that it's here because of Volcanoes on the Isle of Mull.
