I am wearing a Rudraksha mala with 4 beads of 13, 4,5 and 6 mukhi. Recently while taking bath the whole mala fell down and a very minute part chipped off from the 13 mukhi bead. The chipped part would measure about 1 mm in size and it was from the middle of a mukhi. I have that small part with me but don't know if it is still ok to keep wearing this bead. Please suggest if I can offer some puja and keep wearing this bead.
