A natural pearl and diamond pendant that once belonged to doomed French Queen Marie Antoinette was sold at auction for over $36 million in Switzerland on Wednesday. The sale sets a new auction record for a natural pearl, according to auction house Sotheby’s.

The buyer wanted to remain anonymous, the auction house added.

The pendant, which features a drop-shaped, 2.58-cm (about 1-inch) natural pearl, had a pre-sale estimate of between $1 million and $2 million.

The auction offered a glimpse into the opulent world of the French court during its twilight years.

Diamond and pearl earrings, pearl necklaces and the giant pearl pendant owned by the ill-fated queen were among 100 heirlooms from the Bourbon-Parma dynasty auctioned by Sotheby’s in Geneva. Some of the Marie Antoinette jewelry hadn't been seen in public for 200 years — until now.

The 100 works were sold for a total of $53.1 million, more than seven times the pre-sale high estimate of $7 million. The sale eclipses the previous record for the sale of royal jewels – the $50.3 million realized when the Duchess of Windsor’s jewels were auctioned in 1987.

All told, the 10 Marie Antoinette pieces reaped nearly $43 million.

Marie Antoinette, who was 37 at the time of her death, has become synonymous with the decadence of the French monarchy during the pre-revolutionary era. Historians, however, believe that she never uttered the famous words “let them eat cake.” The quote has long been attributed to the queen, who had purportedly just been informed that her starving subjects had no bread.
