Jewelry related stuff that can affect bitcoin price is when the jewelers start accepting bitcoin as payment like REEDS Jewelers for instance or many others that are already accepting bitcoin payments. these increase the popularity of bitcoin and also they add to its usability which is always good for bitcoin growth.
Bitcoin+jewelry industry?I don`t think this "partnership" has any future.
Women just don`t use bitcoin.Period.They won`t start using it for retail purchases and most likely they will never start using it.Anyway,some ICO can have a little impact over the btc price,because a big part of the newbiers still think that BTC and ICOs are connected in one way or another.
first of all what you think is just a guess. it is far from reality. the reality is that "Bitcoin + jewelry" has already happened. if you do a quick google search you can find numerous cases of it.
here are a bunch of links:

secondly the newbies who think the way you said here also have so little amount of money that hey also lost a lot of it so they have even less eventually. these people don't have any impact on a big market like bitcoin's.
