These niobium raindrop hoop earrings are each made with a single piece of 20 gauge wire, anodized into different colours. The shades of the anodized & hammered wire seems to change constantly so different angles & lighting will show different shades in any of the colours available. Niobium wire is considered hypoallergenic so these earrings would be great for most people with sensitive ears. They are shown on my hand in in dark rose gold pink (a colour that really changes shades), yellow gold, green, dark indigo (a interesting & moody blue purple) & a purple that can lean to bright pink shades. As this wire is anodized by hand, please expect subtle variation in colour in each pair of handmade earrings. The earrings are designed for regular piercings, are about 1 1/4" long & will be shipped in a splurge gift tin. Please expect subtle variation in each pair because they are handmade.
