Wearing a shell necklace: styling, lengths, and how it holds up in saltwater

Wearing a shell necklace: Styling, lengths, and how well it holds up in salt water. In short: A shell necklace looks best when worn short, between 40 and 45 cm, and paired with solid-colored tops with an open neckline. Genuine shell pieces lose their luster in salt water over time, but a stainless steel shell motif does not. Ultrasonic cleaners are the most common cause of damage to stones that have been glued in.

The shell necklace is back every few years, and it now lasts much longer than a single season. The reason is practical: it works just as well with linen, swimsuits, and a white T-shirt, without the need to coordinate it with anything else.

The right length makes all the difference

Shell necklaces look best at 40 to 45 cm because the motif sits on the collarbone rather than disappearing into the neckline. At 50 cm or longer, the pendant slips into a zone where it catches on the fabric with every movement. If you already wear a longer necklace, you can layer the shell necklace over it. For guidance on how to space the necklaces, see the layering guide.

Genuine shell or shell motif

Necklaces with genuine cowrie shells or mother-of-pearl discs look great in summer, but they react to salt water, sunscreen, and chlorine. Mother-of-pearl becomes dull, the drill holes widen, and the piece is often ruined after two holidays. A stainless steel shell motif does not have these issues: it remains waterproof and tarnish-free, even after a third dip in the sea. That is why we use the metal version at Corelune. What it cannot do is replicate the irregular shimmer of genuine mother-of-pearl—every metal piece looks the same.

How to wear it in winter

A shell necklace is not just a summer piece if you wear it short and over a thin turtleneck instead of bare skin. It loses its impact against chunky knitwear. Another winter styling option: pair the necklace with a simple chain, and the shell motif will read more like a design element than a beach theme.

Frequently asked questions

Can you wear a shell necklace in the sea?

Yes, if it is a stainless steel necklace with a shell motif, as salt water will not damage the material. Rinse it briefly with fresh water after swimming to remove any salt residue from the links. You should remove necklaces with genuine shells or mother-of-pearl beforehand, as their surfaces will become dull over time.

What color suits a shell necklace?

Silver-colored shell necklaces pair with cool colors such as white, blue, and gray, while gold-colored ones suit beige, brown, and green. If you combine both, wear the shorter necklace in the same color as your earrings. The rest can be mixed.

Are shell necklaces still on trend in 2027?

The trend has been going strong for several summers and has evolved from a festival piece into everyday summer jewelry. Smaller motifs under 15 mm and individual pendants are particularly popular, rather than full rows of shells. What else is coming is explained in the trend forecast for spring and summer 2027.

Can toothpaste be used to clean jewelry?

No, toothpaste contains abrasives that will permanently scratch polished surfaces. On coated pieces, it will also wear away the coating. Warm water with a drop of dishwashing liquid and a soft toothbrush will achieve the same result without causing damage.
