Ram Janam Ram (b Feb 3, 1991) of Rishikesh, Uttarakhand has made nine conches of various sizes since 2013 using mud and wall putty, which can also be blown. The smallest is 10 cm long and 6 cm wide, while the largest is 25 cm long and 14 cm wide. The conches sound very similar to the natural conch (shankh).
