Timberlake himself only had one, a yellow-gold domed ring with a hammer finish.
The couple had Leor Yerushalmi of The Jewelers of Las Vegas design their wedding bands, after Timberlake previously asked for his assistance to create Biel's engagement ring.
The actress, 30, opted to go with four stackable rings, but she just wore one when walking down the aisle.
The first and the second rings are white gold with a black rhodium finish and surrounded by diamonds. Both rings share the same diameter. The two other bands are similar to the one belonging to the 31-year-old singer, reported People magazine.
The couple tied the knot at the Borgo Egnazia resort in Fasano, Italy, on Friday, October 19. The new bride wore yellow pear-shape diamond drop earrings, set in 18-karat rose gold and micro-set with 96 extravagant pink diamonds designed by jeweler Martin Katz.
