In order to purify and also increase its efficacy, some regularly dip the ring in cow's milk, turmeric water or saffron water overnight during full Moon night preferably, as there is a belief that their beloved Navaratna would look after the owner well to the extent the owner looks after the Navaratns. This also includes in not indulging in drinking, debauchery, gambling and other vices when wearing the ring.

Even off the counter, Navaratna rings have beneficial effects on the wearers though not so pronounced as the authentic custom made ones.

Warning about wearing the rings made for others. Though these rings with stones of uniform size could be worn safely after they have gone through a process of purification; those rings that have been 'tailored' for a particular owner with, one or more stones bigger than the rest should never be worn by another unless the planetary positions coincide with that of the original owner; which is very remote. The results could be malefic to those whose vibrations are different.
