Pretty rock of the day: Grave Yard Point Plume Agate

[stephbg]

Grave Yard Point is in Idaho, USA, and must be an interesting place. From it seems to come a steady supply of plume agate, which is rapidly becoming one of my favourite kinds of rock. Plume agate comes mostly in whites, blues, greys and browns and forms dreamy three dimensional shapes within transparent and semi-transparent crystal. Today's microscope shots reflect today's stormy weather perfectly, and I'm very excited by the potential here.
