Third iteration of Tangereen with a bit of Paradoxy Effect. This one is rather fancy, so probably best used as a Display font. The center portions of these glyphs make me think of sliced oranges and moon phases. They could act as cabochon settings, as well! So you could use these shapes to make jewelry set with a birthstone, monogrammed pendantsinsignia, and so on.
