What Makes a Precious Stone Expensive
Price depends on rarity, color, clarity, carat weight, and market demand. Stones with vivid color, minimal inclusions, and large sizes command the highest prices. Auction records and certified provenance further increase value.
Top Most Expensive Precious Stones
The Pink Star diamond sold for over $71 million, making it one of the most expensive gemstones ever auctioned. The Blue Moon of Josephine, a vivid blue diamond, reached over $48 million. The Sunrise Ruby, a rare Burmese ruby, set a record price per carat for colored gemstones.
Other high-value stones include the De Beers Millennium Star, a colorless diamond, and the Graff Pink, a rare pink diamond. Large, fine-quality emeralds, sapphires, and alexandrite also appear among the most expensive precious stones due to scarcity.
