Agate Scotland

This stone exhibits a particularly fine "3D" aspect as regards its concentric fortification banding. It was found in the beach shingle at a small beach in the Usan area in 2013. It is also another example of the highly weathered stones found occasionally at Usan, which have very waterworn skins that appear almost like porcelain. Sometimes once cut, the interior markings appear completely silicified. I have a particular interest in stones of this type from the area.
