Ancient knowledge tells us that a seaman from the Gulf of Naples
had allegedly started engraving on seashells during a long sea voyage.

Cassis Madagascariensis

Cassis madagascarensiss

The best seashells are today considered to be those from Madagascar, Bahamas and South Africa and they are called Cassis Madagascarensis. Such seashells, used in Meaornamenta cameos, distinguish themselves from the rest as they exhibit a strong contrast between the upper layer, which is white, and the bottom one, which in the best-case scenario is dark brown.
