Mermaid & Stone is a crystal and natural treasure brand founded by Heleen, who personally selects distinctive stones inspired by a lifelong fascination with finds from beaches, dunes and everyday places. Its collection brings together natural gemstones and crystals chosen for their colour, shape and character, with the aim of adding beauty to a home and offering personal reminders of dreams and goals.

Products include individual display stones, such as Brazilian amethyst on a stand, rose quartz and a quartz geode from India, as well as curated collections like The Soft Collection. These hand-assembled groupings combine stones in complementary colours, forms and textures. Each natural piece is unique, and some listings let customers receive the exact stone shown in the photographs.

Mermaid & Stone also shares the traditional symbolism associated with particular stones, including rose quartz and self-love, and amethyst and calm. Customers can join the free Sparkle Club for updates about new stones, exclusive offers and invitations to live shopping events.
