gift

this is a gift to me from a woman i have come to really care about over the last few months. she can not drive and does not leave her room often, so this was picked out by someone else. my friend pointed this out and told me it would be ok if i returned this one and found a necklace i would like better. i do not dislike this, though it is not my style. i am not sure how to proceed. my dad taught me that being gracious was a gift to the giver. i want to make her happy more than i want a new necklace. should i exchange it?
