Rappers and diamond watches

What do you think about most rappers that have this obsession with destroying their watches with aftermarket diamonds?

Honestly, I’ve never understood why rappers like to wear diamonds so much. It seemed to me that it’s absolutely devoid of style, but recently I was given such iced out diamond rolex and I changed my mind, because these diamonds not only look very beautiful and expensive, but also perfectly combined with any bow and help to stand out from the crowd.
