Posidonia - Posidonia oceanica is a species of seagrass that is endemic to the Mediterranean Sea. This marine plant forms large underwater meadows that are considered to be of high importance to the environmental conservation of the region. The fruit is free floating and known in Italy as 'the olive of the sea' (l'oliva di mare).

Mineral Amber - Amber is the name for fossil resin or tree sap that is appreciated for its colour. It is used for the manufacture of ornamental objects and jewellery. Although not mineralized, it is sometimes considered a gemstone. Amber is heterogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform.
