Oceanic chalcedony number one

Ocean chalcedony freeform 

with a height of about 9 cm
a width of approximately 7 cm and a thickness of approximately 2 cm

From the already closed Moravato mine on the Ambolobozo Peninsula on the northwest coast of Madagascar.
This mine could only be operated at low tide. The high tide washed over the rocks consisting of ocean agate and thus did not allow mining.
