In Jainism, a Chakravartin (universal monarch) is described as having the following main symbols or “ratna” (jewels):

• Saptaratna (seven jewels): Sudarśana Chakra (a miraculous spinning wheel), a queen, a large army of chariots, abundant jewels/jewellery, vast wealth, a large army of horses, and a large army of elephants. These signs signify his worldly power and the means with which he rules justly over all lands. Some texts list navaratna (nine jewels) or even fourteen jewels, adding other offices or assets; but the classic Jain listing is the seven jewels. Some Jain works also mention a prime minister and a son in extended lists. The core idea remains: the Chakravartin has sovereign may-iconic symbols that enable his universal rule.

• Additional marks sometimes described in broader lists include a colossal wheel (Chakra) and the aura of authority around him; in some depictions, his procession and entourage symbolize his dharma-ruled governance.

Note on tradition differences:

• The core set of seven jewels is widely cited in Jain sources.
• Some later or different traditions (and related Indian iconography) mention extended sets (navaratna or 14 jewels). The exact enumeration can vary by Digambara or Śvetāmbara texts, but the essential meaning—universal kingship via symbolic treasures and military might—is consistent.

If you’d like, I can point to Jain-era references or summarize specific passages from canonical Jain works that name these jewels and describe the Chakravartin’s signs.
