Kitsune Star Gem Question

[Gobo Fushigi]

Is it mechanically important that the Kitsune Star Gem glows like faerie fire? Is it casting faerie fire?
The complete description is this: This magical jewel glows like faerie fire, shedding light as a candle. It acts as a pearl of power, except it only allows a itsune to recover a spent use of a spell-like ability of the appropriate spell level.
I think it's odd that it glows like faerie fire and doesn't simply glow, if there's no mechanical purpose. For comparison, I haven't been able to find other items that glow like faerie fire.

No, it's just kitsune flavor. It sheds light as a candle.

From Faerie Fire, the spell:

"A pale glow surrounds and outlines the subjects."

So I would take it to mean instead of the whole gem glowing, there's just an outline around it that glows and shines as a candle.

Mechanically, I can't think of any difference this would make. I'd agree with Ipslore the Red and say its just flavor for it.
