Drake bought Tupak Shakur's gold, ruby and diamond crown ring for just over $1 million. The one-of-a-kind bauble was on offer this week at Sotheby's. ... the other red — valued at $300,000 apiece.

(The crown has gone through several reincarnations since the restoration of the monarchy in 1660). Though it is known as the Black Prince's Ruby, it is, in fact, a 170 carat red spinel.
