Pearling allows to build up layers of nacre on an initial shape. It allows to explore pearls of very different types, scales and shapes than nature. For example, it can harden a soft or rubbery material.
Exactly like in oysters, the process needs to build up on an initial structure. Many materials can be used for that purpose, from metal to glass or ABS. A few specific material won't work, like Polyethylène or wood.
Nacre has very specific mechanical properties. It is a 95% ceramic based composite (ceramics haver the tendency to be fragile), but the inner structure of the material makes it very resistant to fracture (non fragile). This could open up interesting specific uses.
