Gabboim, I’m sure that many Jews give bracelets. However, many also give rings and the giving of a ring prior to the Chuppah is recognized as something other than for the sake of Kiddushin. Similarly, while those you know might give the ring at the Vort, many also give it when they get engaged.
What intrigues me about this is that the original source for the non-Jewish custom to give an engagement ring probably is Kiddushin, since the source for the Western custom is dated back to Roman custom. That shouldn’t matter now though as everyone knows that when one gives a ring at the time of the engagement it is not for the sake of Kiddushin but rather as a romantic gesture/sign of commitment.
