Payyannur Pavithra Ring
പവിത്ര മോതിരംA ritual ring whose band is tied in a knot — the pavithram, the same knot of darbha grass a Brahmin wears at a rite, rendered in gold or silver and worn for ancestor offerings. It is cast by lost wax and finished by hand, and it is made nowhere else. Its geographical indication application carries number 6, which makes it one of the first half-dozen filed in India; it was granted in 2010-11, a decade behind applications numbered after it.
