Top sapphires (rubies and emeralds) cost more than diamonds. The reason: Colored gemstones are rarer in nature than diamonds. A combination of characteristics set their value including their beauty, rarity and durability. Carat weight, cut, clarity and country of origin can also drive their prices up. Vibrant blue sapphires are the most sought after in jewelry. Heat treated sapphires are accepted as long as the seller discloses it, and the price should also reflect the treatment. Without heat treatment, there would be few gemstone quality sapphires on the market to buy. Beautiful, natural, unheated sapphires are more expensive than heated, or lab grown sapphires due to their rarity and demand. Go here to learn more about sapphires.
Today let’s look at 5 of the most gorgeous sapphires in the world. It’s such fun seeing top of the line! All except for one (which is a smaller wearable size) sold for multi-millions of dollars. Don’t we, ordinary people, wish we could afford the grade of sapphires just like them?
1) In 2021, an 11.9 carat Kashmir Sapphire sold at auction at Fellows in Birmingham, England for £175,980 (or $238,184) after a bidding war. It is a rich, natural, velvety blue untreated sapphire of spectacular clarity. While large indeed, the next 4 sapphires are huge gemstone-quality-sapphires raising their value to more zeros!
2) The Belle of Asia Sapphire is a cushion cut 392.52 carat sapphire pendent, surrounded by diamonds as a necklace. It was discovered in Sir Lanka in 1926. Lord Nuffield, the founder of Morris Motors, bought it in 1937. Sapphires of its size, color, and clarity are extremely rare. The Bell of Asia Sapphire disappeared into private hands for the next 40+ years, then surfaced in 2014 to be sold at Christie’s for $ 17.7 million to an anonymous buyer who most likely lives in the Middle East.
3. The 35.09 carat antique cushion-shaped Regent Kashmir Sapphire ring is the world’s most expensive sapphire per carat. It broke the record for price in 2025 at Christie’s in Hong Kong. The cost was $12.1 million. As you may have guessed, it’s a natural, unheated, rare, vivid blue sapphire from the storied Kashmir mines. It is set in platinum flanked by round diamonds.
4) The Richelieu Sapphire Earrings, a pair of cushion-cut natural Kasmir earrings weigh 26.66 and 20.88 carats respectively. Owned by Odile de Richelieu (1879 - 1974), they were sold in Geneva at Sothebys for $8.4 million in 2013. The earrings are suspended by a star of cushion and pear shaped diamonds. According to the Swiss Gemological Institute, the pair of sapphires match perfectly in size and shape. The hue is velvety blue and the clarity excellent "with only microscopic inclusions. A matching pair of natural sapphires from Kashmir of this size and quality is very rare and exceptional.”
5) The Logan Sapphire is the most accessible to us common folk, as it resides in the Smithsonian Institution. It was donated by Rebecca Pollard Guggenheim Logan in 1960. The Sri Lanka gemstone, at 422.98 carats, which is the size of a large chicken egg, is one of the largest velvety blue sapphires in the world. The mixed cushion cut sapphire is set in gold and silver as a brooch and surrounded by 20 round brilliant cut diamonds. Multiple sources list its value as $2.5 million.
With colored gemstones (sapphires, rubies and emeralds), color is the most important of the 4 “Cs” (color, cut, carat and clarity) in determining their value. Seeing Kashmir and Sir Lanka sapphires always makes a jewelry lover want one, doesn’t it? Commercial grade sapphires are never as velvety blue. Today the Kashmir and Sir Lanka mines are closed, making these sapphires all the more rare and valuable!💰💸🤑
