The wedding was held at Vienna's sumptuous Palais Coburg, and Anna Netrebko wore a 18 carat white gold and diamond tiara resembling the one worn by Kate Middleton at her wedding to England's Prince William in 2011. Estimated value: 1 million euros ($1.09 million).
Following the official ceremony, the couple took a carriage ride through Vienna's inner city and on to Liechtenstein Palace, where fireworks were due to welcome the 180 guests, including tenor star Placido Domingo.
The dinner and celebration in the Hercules Hall were planned to last until the early morning hours.
Anna Netrebko, a resident and citizen of Austria, met Eyvazov in 2014 in Rome. The couple had initially considered marrying in St. Petersburg, but Eyvazov, 6 years Netrebko's junior, told the Austrian magazine "News" that they had decided that Vienna would be the right place for a romantic wedding.
