Damon Dash is telling more tales about his estranged business partner, Jay-Z. His latest: that Jigga set off a feud with Kanye West by refusing to bestow his bling on Kanye.

Dash claims the simmering beef dates back to a 2003 Chicago concert, where the then-up-and-coming Kanye expected ruling Roc-A-Fella artist Jay to “knight” him by presenting him with a gleaming chain.

But, according to Dash, Jay didn’t want to fork over the chain.

“This n- [Kanye ] was like, ‘Wow. [Jay-Z] ain’t going to give me the chain,’” Dash alleges in December’s Complex magazine. “I had to take off my chain and give it to him, and I was heated. I had the real canary diamonds. That s- cost $40,000! I told Kanye, ‘Yo, you got to give that back when we get off this stage!’”

Dash contends that after Jay-Z violated the code of hip-hop chivalry, “Kanye hated Jay-Z. Dash, whose business relationship with Jay ended badly, has trotted out the story to hype his latest protege, rapper Jim Jones.

“This is sad,” says one source. “Damon does this every time he’s promoting an artist. He just makes things up.”
