The GI Registry recently issued an order on the Payyannur Pavithra Ring, a traditional adornment from north Kerala, stating that "the use of sentimental of religion does not bar for registration."
"Payyanur Pavithra Mothiram is a uniquely crafted ring shaped like a knot and considered being a sacred ornament. Usually Payyanur Pavithram is being made of Gold and Silver. The Pavithram is to be worn on the right ring finger by the person performing Vedic Karmas. It is believed that this ring will bring luck and grace to anyone who wears it with the deep devotion..." "It means the ring made of gold or silver in the region is the subject matter of the GI. This is regularly in use since the Year 1011. After going through the arguments ... the ring is the product available in the particular region and famous in the name of Payyanur Pavithra Ring having specific quality. The applicant has already submitted the certified Map in support of the Application. In view of that the product Ring is the goods of GI and use of sentimental of religion does not bar for registration."
Having said all of this, I must also point you to this article from the Hindu in 2005 that I came across earlier, based on a study by the Centre for Heritage Studies in Kochi, which argues that "Ethnic ornaments, which were once restricted to certain social sections and religious groups, are now transcending the barriers of religion and caste." Specifically,"Pavithra Mothiram was traditionally worn by men of the Brahmin community in connection with some rituals that they performed....Gone are the days when the Brahmin community alone wore this ring, which was also the specialty of jewellers from Payyannur. The ring is now widely used by men of all caste and religion and available at almost all jewellers across the State."[Image: Payyanur and Kerala; from wikipedia]
