Fashionology is known for luxurious, fantasy-inspired jewelry distinct for its dark, eclectic aesthetic. Rachel Duister founded Fashionology in Rotterdam, Netherlands, after growing tired of choosing from the same monotonous jewelry options. Fashionology's designs often utilize semi-precious gemstones like rubies, quartz, jade, and turquoise, as well as other organic items like fossils, sharks teeth, rocks, and wood. Fashionology products can be spotted celebrities like Kristen Stewart and Ashley Smith, and have been profiled in the best fashion magazines and blogs, including Cosmopolitan, Glamour, and Elle. Each Fashionology piece is made in The Netherlands and comes with a certificate of warranty.
