The ‘Mona Lisa of pink diamonds’ is one of the rarest on Earth — and just sold for $14.6M

A rare 24-carat pink diamond known as The Bulgari Pink sold for $14.6 million at a Christie’s auction in Geneva on 10 November. It had been unseen for more than 70 years, and its sale drew attention to the scarcity and market appeal of high-quality pink diamonds.

The emerald-cut stone is classified as Type IIa, a category comprising fewer than 2% of natural diamonds, and was described as exceptionally clear and free of imperfections. Acquired in India’s Golconda region in the 1950s, it was set into a ring by Bulgari; the previous major sale of a high-quality pink diamond was The Eternal Pink, which fetched $35 million in 2023.
