It's actually symmetrical. I drew one quadrant of the symbol and then rotated it around four times. It's probably the viewing angle that makes you think that. On the sides the seam wraps around the ring, while on the top and bottom the ring has a hole. It's the same diameter either way, but one the ring's hole breaks the symmetry. The up, down, left and right points are the same distance from the center, while the four 45 degree angle points are a shorter distance from the center - like the rings that DC Direct put out.
Lol. They were intended to look different. ...but I assume we're still talking in context of the shape of the symbol. I was thinking about that. It may be a bit of an optical illusion on two fronts: one the phenomenon I mentioned earlier... and two, I noticed that the DC Direct ring has an oval in the center instead of a circle. So, even though the perimeter of the symbol is symmetrical, the interior is not. The oval in the center is taller than it is wide. In mine, I did not use an oval or a circle. I decided that it was more Star Saphirey (new adjective I'm coining ) to use an actual gem for the central lens. I used a faceted, octagonal lens. I like the effect, but it is definitely more symmetric than the oval that DC Direct used.
Yes the ring I have has an oval in the center. Which goes back to what I was saying. The ring is supposed to be long top to bottom than side to side, hence the oval. And you know a gem can be in the shape of an oval.
