The curator of the museum tells us that such oval amulet boxes are known as kerima, which means kidney, due to their shape.
The shape of the amulet box on this necklace is unusual.
The historical buddha is seated on a lotus, calling Earth to witness with his right hand, the other holding an alms bowl. In front of him, there are two arhats.
Manjushri is seated in the vajra position on a couple of mythical creatures, brandishing his sword and holding a manuscript at heart level with his main hands. The other hands hold a bow and an arrow. He is adorned with a five-leaf crown, jewellery and a celestial scarf. His hair is topped with a lotus bud finial.
