I know people who make a lot of money selling drugs, and can't really just take it all to the bank, instead of having a whole bunch of cash laying around, they invest it in jewelry, cause the value doesn't really depreciate, it's a pretty safe investment. Hope that answered your question.
I like Ghostface "Sun God" chain, and the Gucci chains from back in the 80's are making a big comeback, Ricky D got some nice jewelery, and Gucci Mane's Bart Simpson chain cracks me up, Loso's "Word is Mine" chain was pretty ill, and I think it was 50 who had the chain with the iPod in it, playing his video, that shit was funny too. How about Juelz Santana rocking his adlib around his neck with the "A' chain. Yeah not really my focal point, but some cats get really creative with theirs, these guys is who's doing it
