the Grottos are a classic, cool, rectangle design with a recessed lens. These understated frames with a unique colorway will enhance the simplest of looks.
The Green Grotto Caves are on the north coast of Jamaica. Named for the green algae that cover its walls, the structure of the cave is strikingly different from inland systems; the cave is a Flank Margin Cave (old mixing chambers at the edge of the fresh water lens with the sea water) with two well-defined levels apparently indicating two periods with differing sea-levels. The innermost cavern contains a crystal-clear underground lake.
