As of October 29, 2015, two standout Katy Perry singles are officially 10x platinum in the United States.
Venturing into that coveted “diamond” territory are “Teenage Dream” single “Firework” and “PRISM” smash “Dark Horse.”
The singles represent Perry’s first to achieve the diamond distinction in the United States. Perry’s next-most-certified singles include “ET” (8x platinum), “Roar” (8x platinum), “California Gurls” (7x platinum), and the “Teenage Dream” title track (7x platinum).
Under the terms of the RIAA’s digital singles program, a 10x platinum/diamond certification confirms a US unit total in excess of 10 million. One unit is equal to 1 paid download or 100 streams.
