The ocean calls to us......these shells tumbled by the ocean, onto the sand and collected by Designer Robin Renzi can now be worn as "gifts from the sea". Through the unique technique of electro forming one side of the shell is covered in 99.9% fine silver while the other side exposes the natural beauty of each shell. For this one of a kind necklace we have strung together and almost pure white shell and a Persian Turquoise Bead for a pop of color. The shell measures 0.75" x 0.75" at its widest and the turquoise measures 1/2" x 1/4". The charms hang on an 18” 1mm black cotton cord with a sterling silver button closure.
