'Crowns' in the Bible

In a circle around the throne were twenty-four other thrones, and seated on those thrones were twenty-four elders. They were dressed in white clothing and had golden crowns on their heads.

the twenty-four elders throw themselves to the ground before the one who sits on the throne and worship the one who lives forever and ever, and they offer their crowns before his throne, saying:

Now the locusts looked like horses equipped for battle. On their heads were something like crowns similar to gold, and their faces looked like men's faces.

Then another sign appeared in heaven: a huge red dragon that had seven heads and ten horns, and on its heads were seven diadem crowns.

Then I saw a beast coming up out of the sea. It had ten horns and seven heads, and on its horns were ten diadem crowns, and on its heads a blasphemous name.

His eyes are like a fiery flame and there are many diadem crowns on his head. He has a name written that no one knows except himself.
