A clean ocean collaboration

Dune Jewelry & Co. is teaming up with 4ocean to help keep our oceans clean! Together with Dune’s experienced artisans, we’ve designed a collection of fine sterling silver jewelry that funds our global ocean cleanup operation and transforms recovered ocean plastic into wearable keepsakes and heirlooms that you and your family will treasure forever.

From the earth, for the earth

Every piece of jewelry is handcrafted in Dune’s Boston, Massachusetts, studio using hypoallergenic .925 sterling silver, hand-picked and ethically-sourced earth elements from Dune’s Sandbank, and certified 4ocean Plastic recovered by our crews in Florida, Indonesia, and Hawai'i.

Pull up to 10 pounds of trash from the world’s oceans, rivers, and coastlines with each piece you purchase from the 4ocean x Dune Collection. Your purchase ships directly from Dune and comes with their Lifetime Warranty and Happiness Guarantee.

The Dune Sandbank™

As one of the world’s largest collections of sand and earth elements, Dune’s Sandbank features natural materials like sea shells, clay, soil, sand, stones, and flower petals from over 5,000 iconic and memorable locations around the world.

All elements in the Dune Sandbank are collected ethically by people just like you! Since 2010, Dune’s customers and community members have sent in sand and earth elements from their vacations, travels, weddings, honeymoons, and more to capture their personal experiences.

There are often extra elements leftover once their custom pieces are created. In fact, a single cup of any element can be used to make over 1,000 designs. To ensure no materials go to waste, Dune authenticates all unused elements before adding them to the Sandbank so others can add them to their own custom designs.

Hawai'i shells sourced with extra care

One thing you’ll never find in Dune’s Sandbank is sand from Hawai'i. As a response to erosion caused by the massive dredging that occurs to build luxury resorts, Hawai'i passed a law in 2013 that makes it illegal to remove sand of any kind from the islands, even the sand stuck to your feet. While empty shells and shell fragments are still legal to take off the island, opihi limpet shells are important to Hawaiian culture and can only be harvested under certain conditions.

All of the opihi shells used in our jewelry were ethically harvested by a native Hawaiian who shared a single meal’s worth of shells with Dune after serving this delicacy to her family from her home on Oahu. Even that small amount will keep Dune’s sandbank stocked with opihi shells for years to come, which makes it possible to craft beautiful jewelry that captures the essence of the islands without causing cultural or ecological harm.

About Dune Jewelry & Co

Dune Jewelry & Co is a woman-owned small business founded in 2010 by kitchen table entrepreneur Holly Daniels Christensen, a wife and a mom of two young daughters. Ten years ago, Holly began making handmade jewelry using local beach sand from Cape Cod and gave it out to friends and family as gifts. She quickly discovered everyone had a special place that resonated with them personally and, at that moment, Dune Jewelry was born!

Now, Dune Jewelry captures your most cherished travel memories and unforgettable experiences by creating fine experiential jewelry with sand and natural elements from around the world. All of Dune Jewelry’s patented designs are exclusively handmade in the USA.
