The North Star was associated with the cosmological position of the Emperor since ancient times.
Like the pole star, unmoving and central in the Heavens, so too the Emperor was seen as the link between Heaven and Earth, a point around which the cosmos revolved. The association of the Emperor with the North is also seen in the throne, audience hall, Imperial Palace, and Imperial capital as a whole being organized to face south (such that the people, facing towards the Emperor, would be facing north).
In Japan, the North Star is deified as both Shinto kami Myôken-shin 妙見神 and as Buddhist bodhisattva Myôken bosatsu.
The bracelet is 4mm thick, weighting 48g. The stone is a AAA blue zircon stone measuring 12.4*6.5mm.
