These tanzanite stud earrings are based on the timeless halo style. The halo style originated during the early Georgian era, which lasted from 1714 to 1837, and has gained popularity since its origin. These stud earrings feature trillion cut tanzanite gems in the center encircled with natural white zircon rounds in a halo pattern. Trillion-cut gemstones are rarely offered as manufacturing is extremely difficult given the symmetry and geometry of this cut. These tanzanite halo stud earrings are further beautified with fine metal beads that lend tiny gem-like glitter to them. Made in durable sterling silver, these earrings are timeless and have the beauty to enhance all your looks. Tanzanite is considered one of the rarest gemstones in the world as there is only one mining location in the world.
