Coaster, slice of agate

Original bottle coaster made from a repurposed slice of agate. This is a variety of chalcedony, microcrystalline quartz sourced from Uruguay. It features well-defined concentric bands in orange to honey colours, typical of carnelian agate. There is a small central cavity corresponding to the formation of a geode. Its surface is polished and can be used on a festive table as a coaster for a fine bottle. In perfect condition. Dimensions: length 16 cm, width 9 cm.
