3. The Crimson Flame—$18.38 Million
The Crimson Flame might sound like a cool superhero name, but it’s actually the title given to the 15.04 carat ruby ring that sold for $141,800,000 HKD (approx. $18.38 million USD at the time of sale) at Christie’s earlier this month. The pigeon blood ruby was mined in Myanmar and is a well-saturated stone for its weight and size making it all the more valuable.
