Chromium

The J-type 327 Nubian royal starship was covered in chromium for decorative purposes.

Chromium was an element used in metallic objects, and could provide a mirror shine to the surface. Originally useful in blocking radiation and certain forms of laser attacks, it came to represent nobility on such planets as Naboo.

The J-type 327 Nubian royal starship, J-type diplomatic barge, J-type star skiff, and H-type Nubian yacht were fully covered in chromium. In Naboo culture, non-royal starships were forbidden from using chromium plating.^[1] An exception to this was Padmé Amidala, who continued to use fully plated ships even after stepping down as Queen of Naboo to represent her people in the galactic senate.

The royal N-1 starfighters, used to escort the starships of Naboo dignitaries, wore partial chromium plating.

The Modirin Mining Concern was responsible for a large "chromium rush" on Aduba-3 which turned out to be a scam involving mine-seeding.

The floating city Ipsus, over Genarius, was coated with chromium to protect against radioactive ion storms.

Ladarra was considered a failed chromium mine.^[2]
