Understanding Ruby Prices
Rubies are the most valuable colored gemstone, with top specimens exceeding diamond prices per carat. The "pigeon blood" color -- a vivid, slightly bluish red with strong fluorescence -- is the most sought-after hue. This color is most associated with Burmese rubies from the Mogok valley, where rubies have been mined for centuries.
Origin plays a crucial role in ruby pricing. Burmese rubies command premiums of 2-5x over similar-quality stones from other sources. Mozambique has emerged as a major source of fine rubies since the 2009 discovery of deposits in Montepuez, and top Mozambique rubies now rival Burmese stones in quality. Madagascar, Thailand, and Sri Lanka also produce notable rubies.
The ruby market has shown consistent appreciation for investment-grade stones. Untreated Burmese rubies over 3 carats with fine color have appreciated 5-10% annually over the past two decades. At major auction houses like Christie's and Sotheby's, record-breaking ruby prices continue to be set, confirming the ruby's status as the "king of gemstones."
