Seashell Shape Necklaces in Sterling Silver  

Natural Shell Pendants Set in .925 Sterling Silver

Shell material used in jewelry comes from mollusks that build their protective casings over months or years. The iridescent quality you see in many shells results from nacre, a composite of aragonite platelets and organic polymers. This structure diffracts light across the visible spectrum. Mother-of-pearl rates 2.5 to 4.5 on the Mohs hardness scale, which means sterling silver settings protect the material from scratches during wear. Our collection includes abalone shells from Pacific coastal waters, paua shells from New Zealand, and freshwater shell varieties. Each type carries its own color signature. Abalone tends toward green and blue iridescence. Paua shells show deeper blues with purple undertones. White mother-of-pearl reflects softer, cream-toned light. SilverRush Style has worked with natural shell materials since 2005. We set each piece in .925 sterling silver, the jewelry standard that contains 92.5% pure silver.
