The six blue extensions surrounding a Clamperl's pearl center have often reminded many of thrones, and it is for this reason that many kings or queens with either native or traded Clamperl have placed them in their crowns. Unlike many pokemon used in jewelery, however, this served for centuries to protect the Clamperl; if they were only to be worn by monarchs, they had nothing to fear from overhunting, for monarchs have typically been rare in number. It was said then that how bright a Clamperl shone represented the power of the kingdom its wearer presided over, or when a weak king had one, that a bright Clamperl represented an auspicious fate.

Because Clamperl were so highly regarded as symbols of royal legitimacy, wearing one when not actually a ruler or a Spoink was tantamount to a declaration of rebellion. Therefore, the first act of many rebellions was their would-be leader (or in some cases, many rivals) poaching a Clamperl from waters owned by the crown. As for taking them from Spoink, a pearl which has touched the land loses most of its luster, and calls to mind only the dethroned – and it is remarkably difficult to remove an intact pearl from a Spoink without it hitting the ground first.

The association of Clamperl with royalty lost much of its power during the warring states era, when even weak warlords would fancy themselves great kings and fashion crowns out of Clamperl to boot. And what was left was vanquished during the early years of the Hoenn Republic, when the revolutionaries hunted these pokemon to near-extinction and encouraged everyone, king or commoner, to wear these crown pearls. Today, Clamperl, while expensive, can be seen in many forms of jewelery, and only historians remember that they were once reserved for rulers.
