Royal scarab is very rare, ancient Egypt. Stateite Stone

Description

Egyptian scarabs were used for general purposes, so they were seals like cylinder seals, the buttons of the seals that are in the image of animals, and huge golden rings, and if you put a lob for a ring or a necklace, you could seal pots, letters, and latches with it against the tampering of thieves.
They also carried them as amulets to protect themselves from evil, as they believed that this insect was renewing itself.  The ancient Egyptian who used to worship the sun god Ra was likened between that beetle with a ball, pulling it behind it, hiding it in the sand and then appearing as a new creation by the celebration of the sun during the night and its reappearance in the morning.  The ancient Egyptian represented Ra in the day with the sun disk, and he represented it in the form of a scarab at night
