Copper is a warm metal and with the application of flame, reveals many colors.  You can choose to show more or less copper by reversing them.  One side is colorful copper with a small silver flower disk.  The other features a larger disk, textured and hand cut to look like a daisy. To reverse, simply remove them from the balled ear wire, turn them over and put them back on the ear wire.  Just like that you now have two options.
