What Are the Most Expensive Pieces of Jewelry?
The most expensive pieces of jewelry are rare gems, historic diamonds, and elaborate necklaces that have sold at auction or private sale for hundreds of millions of dollars. Value is driven by size, color, clarity, provenance, and craftsmanship.
Record-Breaking Jewels and Their Prices
The Pink Star diamond sold for about $71.2 million in 2017, making it one of the most expensive gemstones ever auctioned. The Hope Diamond, a famous deep-blue diamond at the Smithsonian, is valued at an estimated $200–$250 million, though it has not been publicly sold. The L'Incomparable Diamond Necklace once held a Guinness World Record at $55 million.
Why These Pieces Command High Prices
Exceptional color, large carat weight, and flawless clarity push gem prices higher. Celebrity ownership, royal provenance, and rarity increase demand. Auction houses and private dealers set records when collectors compete for unique stones. For more details on record jewelry sales, see Christie's.
