Striped Niobium Half-Round Earrings by Keith Lewis.
All of the color in 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 color Keith chooses when he forms a clear oxide layer on the grey niobium shape using only electricity in a liquid bath of washing soda and water. More voltage equals thicker clear oxide, which creates a different interference color.
18k Vermeil ear wires left sterling at top, clip closed in the back. Finished with carnelian cabochons. The half-rounds move freely.
2 inch long x 1 3/4 inch wide
