Real gems from the Sea. Untouched from the ocean. Shaped and formed and polished by the ocean for hundreds if not thousands of years. This limited collection is the culmination of my lifelong hobby of collecting them. I hand drill them (and cry when I break one) and custom make the 14 k gold jump rings. Yes some of the jump rings need some work. With the shells being up to 10 mm thick the size of the extinct mollusks must have been very large. I am working with marine biologists to determine exactly how old they are. There are only approximately 75 total pieces available; some not on this site awaiting jump rings, etc. Of the 75 only 6 are silver. As unique and stunning pieces of jewelry in the cosmos (according to me).
