Final answer:
The shiny luster of metals makes them particularly suitable for jewelry, though their malleability and ductility are also beneficial for crafting intricate designs.
Step-by-step explanation:
The property of metals that makes them suitable for use in jewelry is their luster. This shiny appearance makes metals like gold and silver attractive for creating jewelry. Additionally, metals are both malleable and ductile, meaning they can be shaped into delicate designs without breaking and can be drawn into thin wires for intricate work. While metals' conductivity is important for electrical applications, it is their lustrous quality combined with their malleability and ductility that is particularly desirable for jewelry-making.
