The color on these earrings is created in a clear oxide. Just as a soap bubble has many colors which change as the thickness of the bubble changes, these niobium earrings will show the chosen color when a clear oxide layer on the grey niobium shape is found using only electricity in a liquid bath of washing soda and water. More voltage equals thicker clear oxide which creates a different interference color.
