Is there an infinite soul gem in Skyrim?

Excuse me, but I'm curious about something related to the game Skyrim. I've been hearing rumors about an infinite soul gem, and I'm wondering if such an item actually exists within the game's mechanics. Could you please clarify if there's truly an infinite soul gem in Skyrim, and if so, how one might acquire it? I'm quite intrigued by the idea of having such a powerful artifact at my disposal.
