Kelly Costello, Sole Owner & Designer

Being born and raised on O’ahu, Hawai’i, and growing up near the ocean, I’ve always spent countless hours at the beach — before school, after school, and of course on the weekends and during any free time. The ocean has always been a place where I feel grounded, happy, and at peace. It is my special place to press pause when life gets chaotic, teaching me to slow down, observe, and appreciate the beauty and healing qualities of nature when you embrace it.

Salt & Water Co. was born from this connection, with the vision to inspire and uplift others to feel good through the timeless beauty of nature each and every day. Each design is handmade with love and aloha on the North Shore of O’ahu, crafted in small, sustainable batches with ethically sourced materials — truly making each piece unique and one-of-a-kind. From where it was found, to the meaning it carries — each piece has a story. Every shell, piece of sea glass, and beach treasure is handpicked by me at various beaches across the island. I DO NOT pick up everything I find, and I take care to ensure NO living creatures are inside, returning anything unused to their natural habitat. Our Tahitian and freshwater pearls as well as our semi-precious gemstones, are 100% real and sourced from trusted local artisans.

My mission is to design with intention, creating quality jewelry that lets you embrace your natural beauty and the beauty of nature each and every day.

Inspired by the ocean — & the women who move like her. Embody the strength, softness, and the wild calm of the girl and the sea.
