Blue Chalcedony, Peru For Sale

Blue Chalcedony, Peru. I recently returned from a buying trip to Lima, Peru with this specimen. The vendor did not provide location information, but Google Lens (really!!) identified it as blue chalcedony after anhydrite. Further googling indicates it is a pseudomorph of chalcedony after anhydrite from Rumipata, Peru. Displays nicely with lovely mineral on both sides. As evidenced by the occasional broken tips, the pseudomorphing is not complete. A little over a pound. 5 inches long at the base.
You can save a lot of $$$ on postage with multiple purchases.
