Usha Silver Zirconia Earrings The USHA earrings are shaped like a circle with natural zirconia in the center. The size of the USHA is small, but their natural stone and their beautiful shine, will stand out and illuminate your ear. We love how the zirconia looks on these earrings. The USHA are special and exclusive.They are very carefully crafted. Together with the JAYA necklace they will make a spectacular combo, both with zirconia stones. The USHA are beautiful, elegant and fine earrings.
