Multi-Colored Anodized Niobium Earrings

I cut the rectangles in these earrings from niobium sheet. I created a brushed texture, masked geometric shapes, and then anodized the rectangles at a voltage that produces the blue-green color everywhere except under the masked areas. I removed each mask and anodized at successively lower voltages to produce different colors in each masked area. The sterling earwires are also handcrafted.
