It's random. When going after Kairos pieces you could come in 2nd or 3rd, land on a duplicate artifact, and win a gem with the bonus spin. After completing Kairos you can only win gems from the Gold wheel, so it may feel like less gems, but I've still won up to 5 in a 24 hour period. Other days I get none...but they are definitely still available as a prize!
