the.com/toe ring

means A decorative ring, usually simple metal, worn around a toe rather than a finger — pure adornment, no bureaucracy attached.

from The object itself has deep roots in South Asian tradition, where toe rings (like the Hindi 'bichiya') worn on the second toe are still part of bridal and married-woman jewelry — so, amusingly, the essence's joke inverts the real history: in many cultures the toe ring IS the marriage ring. In the West, 'toe ring' is a plain compound, English simply naming the thing where it sits, and it surged as casual beach/summer jewelry in the late 20th century, detached entirely from any wedding symbolism.
