Celebrating 4 Years with 4ocean | Dune Jewelry’s Sustainable Ocean Jewelry Collection
Celebrating 4 Years with 4ocean: Sustainable Ocean Jewelry That Gives Back
At Dune Jewelry, the ocean has always been more than inspiration. It is where memories are made, where stories begin, and where so many of us return to feel grounded, restored, and connected.
For Holly Daniels Christensen, Founder and Lead Designer of Dune Jewelry, that love of the ocean is part of Dune’s very beginning. What started at her kitchen table with sand-filled jewelry made for family and friends has grown into a brand rooted in memory, meaning, and the places we carry with us.
From the first grains of beach sand she captured in jewelry, Holly’s vision has always been about transforming the beauty of the natural world into something personal and lasting.
That is why our partnership with 4ocean means so much to us.
This May, we’re celebrating four years of working together to help protect the waters, coastlines, and marine life we love. Through the Dune x 4ocean Collection, sustainable ocean jewelry becomes part of something larger: a cleaner future for our shared ocean.
Four Years of Purposeful Partnership
Founded by two surfers on a mission to end the ocean plastic crisis, 4ocean has grown into a global cleanup movement with full-time captains and crews recovering plastic, trash, and debris from oceans, rivers, and coastlines around the world.
As of early 2026, 4ocean has removed more than 50 million pounds of plastic and debris from the environment, one pound at a time.
We’re proud that Dune has been part of this impact through our ongoing collaboration, helping transform recovered ocean plastic into meaningful sustainable ocean jewelry designs that tell a deeper story.
For us, this partnership is personal.
In 2024, Holly joined 4ocean for a beach cleanup in Boca Raton, Florida, where even the cleanest beaches revealed the reality of plastic pollution.
Together, the group removed 65 pounds of plastic and debris, a powerful reminder that protecting the ocean begins with showing up, one shoreline and one pound at a time.
From Recovered Plastic to Meaningful Design
The Dune x 4ocean Collection brings together Dune’s signature sand and earth elements with 4ocean-certified recovered plastic, creating coastal jewelry that carries both beauty and impact.
Each design is handcrafted with meaningful materials, from beach sand and ethically sourced shells to colorful recovered plastics from places like Bali, Hawaii, and Florida. Depending on the design, each purchase helps remove anywhere from five to 30 pounds of plastic and debris from oceans and coastlines worldwide.
It is sustainable ocean jewelry crafted to honor the places we love while helping protect them for generations to come.

Plastic pollution remains one of the greatest threats to ocean wildlife. By choosing a Dune x 4ocean design, you are helping fund real cleanup work that protects those places for the future.
From nautical jewelry that reflects life by the water to earth elements jewelry filled with meaningful sand, shells, and recovered materials, every design in this collection is a reminder that what we wear can also reflect what we stand for.
One Ocean, One Shared Responsibility
The ocean connects us all. From the beaches of Cape Cod to the shores of Hawaii, from Bali’s coastlines to Florida’s waterways, every cleanup matters. Every pound removed matters. Every choice to support a cleaner future matters.
After four years with 4ocean and over 27,000 pounds of plastic pulled thanks to you, we are more inspired than ever to keep going.
Together, we can turn recovered plastic into purpose, jewelry into action, and love for the ocean into lasting change.
