I thought I dropped enough jewels on her
Double entendre. Nas thought he dropped enough ‘jewels’ — as in wise words and knowledge — on her, and literal jewels — necklaces, etc. — to keep her content and behaved.
He may also have been giving expensive gifts to his daughter to try and instill in her the attitude that material things are not a big deal and shouldn’t define who somebody is as a person.
He also gave her a gift more precious than jewellery — spending time and lavishing attention on her to share his wisdom on life. And being a parent, his anxiety and concern over it leads him to one conclusion — he needs to do more of it.
