This shell is used as an important ritual object in Hinduism. Shastra (scripture), doesn’t say ANY SHELL or EVERY SHELL is pure, it’s only Lakshmi Indian Shank that is pure. And these come in two types, normal left side opening AND special right side opening. It is not required to have right-side opening. Left side (normal) opening Shank is perfect for puja. And Lakshmi Shank is even better than perfect. It is said by Conchologists that only one Lakshmi Shank is found among 1,000 normal Indian Shanks. And ALL Indian shanks are pure and auspicious. Depending on quality and number of ridges in the conch cavity Lakshmi Chank shells sell upwards to $2,000. However, our West Indian Chank shells for a fraction of the cost of a rare Lakshmi Chank, and can be used as they are true chank shells and are also considered auspicious and pure (as opposed to lighting whelks- with not internal formation and no ridges in the conch cavity- are commonly substituted are bogus non-pure shells). Priced per shell.
