Demarco Castle

Demarco Castle (born on June 20, 1981 in Chicago, Illinois), also known as Gemstones, is an emcee. There is a Wikipedia article. Castle began his hip-hop career under Lupe Fiasco's Atlantic Records imprint, 1st and 15th Entertainment, where he was scheduled to release his debut album, Troubles of the World, in early 2009. The album was later postponed indefinitely following his departure from the label and a shift away from mainstream hip-hop, coinciding with the discontinuation of 1st and 15th Entertainment. After a brief hiatus, Castle returned to the underground hip-hop scene and subsequently signed with Xist Music, focusing on Christian hip-hop. He released his debut album under the label, Blind Elephant, in 2015.
