Three necklaces courtesy of the ocean. One is 48" of natural coral beads, one is 16" of clam shell beads sporting a 1" mother of pearl bird cleverly carved from the innermost section of a spiral shell, with coral chips and green sea glass. The third is a mystery, is it 16" of real vintage puka shells? The original owner traveled extensively in the Pacific Islands! The imitation est value of 3 is $20. If vintage? Who knows!
