Spell penetration gems

Bonuses for spell penetration can be found on blue, green, and purple gems, but the [Mysterious Fire Opal] currently provides penetration as well. This is believed to have been an error in its itemization, but Blizzard has thus far made no mention of fixing it, which makes it a valuable gem for filling yellow sockets in PvP gear for DoT-based casters (who do not typically care about spell crit and may prefer spell penetration to intellect).
