Megastar Justin Timberlake reportedly gifted his wife Jessica Biel four wedding rings to match her 18-carat engagement ring. It has been revealed. According to People magazine, the 31-year-old singer and actor, who tied the knot with Hitchcock actress in a lavish four-day bash in southern Italy earlier this month, directly collaborated with Leor Yerushalmi of The Jewelers of Las Vegas to design four stackable wedding bands to go with her enormous 18-carat engagement ring, Contactmusic reported. The In Time actor told the magazine that he helped the designer to create the very personal white gold and black rhodium plated engagement ring – which also features two aquamarine elements representing his wife’s birthstone. In total the 30-year-old bride chose four stackable weddings bands, two of which are the same as Justin’s ring and the other two are said to be white gold with a black rhodium finish and covered in diamonds, while Timberlake chose a simple yellow-gold domed ring with a hammer finish. The couple were eager to have equally special wedding rings, which took several months to complete. However, Biel was said to have worn only one of her wedding bands during their ceremony on their special day in Italy.
