25mm x 23mm. Photograph by David Dorman.
Agates as strongly coloured as this stone from the Usan area are rare, but in certain small locations do occur from time to time. Eroded from the host-rock perhaps hundreds of years ago, as has previously been mentioned in other entries written by myself, the colours are affected by weathering. In David Dorman's fine photo of this particular specimen, extensive and detailed orange and grey-black haemocytes (pigment platelets akin to those found in human plasma) can be observed throughout the pink and blue-grey chalcedony. It is my belief that originally this agate would only have been pink and orange in colour. The banding is wonderfully sharp, the colours exquisite and in high-contrast and the photograph for once, does the stone justice. I discovered this agate to the south of Elephant Rock during low tide in a deep gully difficult of access, extending from the shore.
