Our Calypso Sea Sponges are gathered with traditional diving methods. Divers choose not only the best sponges using eco-friendly methods, but also only those that are fully grown.

During harvesting, divers preserve the vital root system by ensuring one inch of the sponges’ base remains intact. This method respects the marine ecosystems and the natural regenerative process resulting in new, healthier, stronger sponges.

Our suppliers and their boats are certified by the Kalymnos council as to not cause environmental damage or pollution.
