Phantom Magatama/Origin

Origin
Magatama (勾玉?), less frequently (曲玉), are curved, comma-shaped beads that appeared in prehistoric Japan from the Final Jōmon period through the Kofun period, approximately ca. 1,000 BC to the 6th century AD. The beads, also described as jewels, were made of primitive stone and earthen materials in the early period, but by the end of the Kofun period were made almost exclusively of jade. Magatama originally served as decorative jewelry, but by the end of the Kofun period functioned as ceremonial and religious objects. Archaeological evidence suggests that magatama were produced in specific areas of Japan and were widely dispersed through the entirety of the Japanese archipelago by trade routes.
