As the collection evolves, PRUM works with a curated selection of carnelian, onyx, jasper, pearls, and other natural stones. Small, rare batches emerge from unique finds — materials available only in limited quantities and treated as part of an ongoing collection.

All materials are sourced intentionally and in small amounts, many from deadstock and existing inventories. Each piece is made to order to avoid overproduction and to ensure a precise, responsible creation process. PRUM approaches jewellery as an object to be collected, worn, and anchored into one’s own life — a personal fragment of form, colour, and stillness.
