What is the difference between the various elemental symbols?

While playing Genshin Impact this morning, I noticed something I had never noticed before. I took a small hiatus, so I’m not sure if this is something new or I was just oblivious to it.

On the character profile, the characters elemental type is displayed on the top-left of the screen. While going through my characters, I saw there are two types of symbols for each element

What are the differences between the two? Does it have anything to do with the character (range/physical/magic)?

Solution 1:

It is about the vision model / region. If you notice, Beidou and Ningguang have the same "square" shell, while Noelle and Lisa use the winged crest. Beidou and Ningguang both come from Liyue, while Noelle and Lisa are from Mondstadt.

Mondstadt has the three wings vision.

Liyue has the square "geode" vision.

Inazuma has the circular design reminiscent of the drums usually associated to Raijin in Japanese mythology and the Shinto religion (also known as Raiden-sama... guess how is the Archeon called)

Snezhnaya has the pointy design based on I-don't-know-what.

Interesting enough, Mona vision is of Mondstadt design. Kaeya's...
