Venus gemstone - Diamond

[myastroblog]

i need some help please.
i'm not clear about some things regarding venus gemstone-diamond


Q-1: ) which diamond do you wear for the planet venus, any particular name for that gemstone?


Q-2 some people wear diamonds(in their rings in their third finger), some wear bracelets which have some diamonds, some people wear it as a pendants in necklace etc etc....
can the diamonds(if it is considered a venus gemstone) harm those people if their horoscope
is having a debilitated/afflicted venus and there are wearing that as said above.
