Affair of the Diamond Necklace
In 1772, Louis XV of France decided to make Madame du Barry, with whom he was in love with, a special gift at the cost of 2,000,000 livres (about $15.1 million in 2020 USD). He wanted Parisian jewelers Charles Auguste Boehmer and Paul Bassange to create a diamond necklace that would be the greatest necklace ever made.
