With iridescent flashes of chrome and lustrous pearl touches.
No beach has the same seashells as another. The shells you’ll find on the coast of Maine are vastly different from what you’d find scattered throughout Northern California sand or washed ashore with the Caribbean Sea. Like sea glass, every shell has its own distinctive look, from swirling conches with pink insides to sparkling, iridescent clamshells. With so much natural beauty to choose from, it’s no wonder nail artists are drawing inspiration from the mollusks for this summer’s manicures.
Seashell nails can be as realistic or as abstract as you wish. You might want to pull from a palette of creams and tans, or color-drench your seashell design in punchy, vacation-ready hues of turquoise and tangerine. You could paint on a seashell motif, or opt for a hyperrealist effect with 3D lines of clear builder gel that resemble the ridges of a shell. And why stop at just seashells when you could incorporate the entire beach? Water marbling, coconut-white auras, and tropical flowers can help transport your set to a remote island getaway.
Find 15 seashell nail ideas, with colorful auras, sunlit chrome accents, and sandy neutrals, ahead.

They’re like a rare seashell you’re tempted to stick in your beach bag as a keepsake.

Make a Splash
Turquoise is one of the defining nail colors of summer 2026, as nail artist Maryna Slynko shared in a previous InStyle story. “It brings a clean, refreshing look associated with summer, water, and vacation vibes,” the artist mused. It’s a natural fit with seashells and starfish.
