The lettered olive shell for this necklace was found at Folly Beach, SC.  All of my cast designs are made by a small foundry located in Portland, OR. 

14kt gold plated shell charm with e-coating (a process that uses an electrical current to deposit transparent abrasion-resistant nano-sized ceramic particles onto the surface of the jewelry, creating a durable protective hypoallergenic and tarnish-resistant finish)

14kt gold-filled chain and findings

necklace length around the neck is either 16" or 18" with a 3" total drop (chain plus the shell pendant)
