Pearlescent

Pearlescent (or Cyan) weapons/items are a confirmed rarity type that are encountered exclusively in the third DLC, The Secret Armory of General Knoxx. They can be found in weapon boxes, dropped by Crawmerax the Invincible, bosses during This Bitch is Payback, and less commonly by Lancers. They can also be dropped by BadAss Bruisers, Lance Pyros, Badass Engineers, Drifters and on rare occasion can be found by opening Crimson Lance chests.

These are the only confirmed pearlescent items, all added with DLC3. Any others found in game not bearing these names are most likely illegitimate such as the "Bitch Bitch" or the "Unforgiven Unforgiven".

Before General Knoxx

 * Pearlescent was an old bug in Borderlands before the advent of the Secret Armory of General Knoxx where "white" weapons would appear over "orange" weapons in the menu. It was fixed in the patch preceding DLC3. For all information for this old bug, visit Pearlescent (Before General Knoxx).
