We also have a larger version of this pendant, which you can find .
At first glance this sun and crescent moon pair look fairly traditional until you notice that they're inscribed with tattoo-like designs that give it a slightly tribal look. Also several of the designs look to be portions of lotus flowers, giving the pendant a southeast Asian or Indian influence.
Another nice detail is how the tips of the crescent as well as several of the sun's rays are curled.
This is a very sculptural pendant, very three dimensional with lots of undulating surfaces, which are accentuated by a dramatic oxidized darkening effect.
When the sun and moon are seen together, they represent the coming together of opposite forces, symbolizing unity and cooperation amidst diversity.
