Among the treasures housed in Shosoin, the "Ruri no Tsuki" (lapis lazuli bowl) exudes a particularly mystical glow. This one-of-a-kind treasure, handed down through the ages to the present day, has been made into an accessory. The base of the Ruri no Tsuki is made of brass, which gives off a warm glow. Beneath it, resin parts that mimic the bowl, which is filled with the deep blue of the night sky, exude a delicate glow.
