Buying shiny blocks

[pyrusbrawler30]

Hey everybody, today i'm setting up a quick trade thread thing... (this will be deleted once the purchase is successful.)

Alright, so... In the main room of my basement that will be under my castle on the new map, i have several prison-like chambers. Each holds a different type of treasure.

one has diamonds blocks,
one has gold,
one iron,
another emerald.
one has a nether portal,
another has my dragon egg,
another my wither skull, Erazor,
and the final one needs:
Circle Stone Bricks

I need 19 pieces of these, and am looking for any sellers. I'll pay an amount i feel is fair. Anyways, any sellers, please reply below!
