Unakite is...

Essentially, it's a term that describes an altered granite that consists mainly of epidosite matrix and large pink orthoclase. I don't think it has any strict scientific meaning. However, it s a stone for collectors that is "pretty when polished up." Said to be found in Oregon and the Appalachiens, it seems to me a common enough rock within Pelagonia over here. Found in the oldest of the old parts of the metamorphic terrain. I just don't know if anyone in Greece has bothered to pretty it up. Maybe we should.
Scale on this slab cut from Dina's cobble: each orthoclase is on the order of 2 - 3 cm.
