Mint.

Fossil Mint shares the celadon-to-mint colour of ordinary Mint, but carries something the rest of the bed does not: marine fossils preserved in the sedimentary layer. Small bivalves, shell fragments, and occasional larger impressions surface across the face of slabs cut from the fossil-bearing strata.

The fossils come rarely. Not every slab will carry visible patterns; the strata that hold them are thinner than the surrounding bed, and a single quarry session yields more ordinary Mint than Fossil Mint. The yard sorts the cut slabs before dispatch — pieces with visible fossil impressions are flagged and packed together, and customers who specifically need fossil-bearing material should request this at the order stage. Honed surface treatment reads the fossils most clearly against the polished ground.
