Aside from the impressive luxury watches, you couldn't help but to spot Shantel's two massive rings on each of her ring fingers. 

One of the rings reportedly cost Floyd $2.5 million and features an 18-carat diamond that is surrounded by 10 one-carat diamonds that dot the shank. The other ring is a huge canary diamond that has yellow and white diamonds around the band.
