Surely the quintessential shell! This polished lion's paw scallop - Latin name nodipecten nodosus - comes in shades of coral and orange on the outside, with bands of purple, pink and white inside.
This is the largest scallop of the Western-Atlantic Ocean and this example has a thick shell smoothed by polishing.
This shell measures 14cm long by 13.5cm across. With large, specimen shells such as this one you will receive the actual shell photographed.
