Pearlescent weapons are a confirmed rarity weapon type that will be encountered in the third DLC, The Secret Armory of General Knoxx, They can be found in weapon boxes, and, can be drop by Crawmerax the Invincible (with a higher chance form Crawmerax the Invincible).

Pre Knoxx
Pearlescent weapons (before DLC3) were super rare, white-colored weapons that resemble standard, common weapons but were generally significantly more powerful. It is unknown if they were intended to be in the original release as is, or if they were either accidentally leaked and/or glitched.
