Polished presentation

Smooth display faces bring the black and smoky gray agate pattern into focus.

Natural variation

Agate is naturally varied. Shape, exact diameter, black and gray banding, translucency, crystal centers and edge texture differ from coaster to coaster. Product photography is representative; every four-piece set will have its own pattern balance and outline.
