Architectural Surfaces Mineralized from Sea Urchins

Urchinite™

Urchinite™ is a biomarble engineered to support marine restoration and architectural design. It is crafted from biocalcites, a naturally occurring marine mineral found in sea urchin shells. Designed with durability and wellness in mind, Urchinite contains no silica, no voc, and is ideal for interior and architectural applications such as countertops, wall coverings, flooring, furniture, and decor. For architects and designers, it offers a material rich in texture, origin, and story — a surface you can trace back to a marine restoration event, one that is about beauty, but also about repair. And for homeowners and builders, Urchinite is a chance to incorporate rare, regenerative materials into bespoke environments that impart enduring value and oceanic beauty.

  • Urchinite™ is a biomarble engineered to support marine restoration and architectural design. Made from biocalcite, a naturally occurring marine mineral found in sea urchin shells, Urchinite is formed by integrating this mineral into a biobased binder, resulting in a durable, marble-like stone material. 

    The sea urchins used are strongylocentrotus purpuratus, also known as purple sea urchins, which are harvested from targeted restoration sites where kelp forests have been severely damaged by them. By harvesting sea urchins from these impacted areas, Urchinite actively contributes to the recovery of marine ecosystems. As the world’s first biomarble made from marine biocalcite, Urchinite offers a regenerative material solution for natural green building and sustainable architecture. 

  • For just a single slab of 5’ x 8’ Urchinite, 1000 square feet of sea urchin are cleared to make way for kelp regrowth, transforming sea urchin deserts into vibrant kelp forest ecosystems.

  • Experienced, commercial scuba divers harvest purple sea urchins from the ocean at kelp restoration sites where sea urchin outbreaks have been particularly detrimental. Once landed, sea urchin biocalcites are mineralized and integrated with a biobased binder - resulting in a durable, marble-like stone material. Urchinite biocalcite surfaces then undergoes finishing, grading, and stringent testing by our team of artisans and scientists to ensure their quality and performance are up to our standards. Each piece is hand crafted, and unique so no two are exactly the same.

  • Urchinite has undergone extensive testing in the lab. It is exceptionally strong and lightweight, with performance that rivals or exceeds traditional stone.

    Urchnite is more durable than terrazzo, quartzite, marble and limestone. It is silica-free, VOC-free, and is resistant to impact, scratch, temperature, stain, and chemicals.
