Rubies have been revered throughout history for their captivating beauty and vibrant red hues. As one of the four precious gemstones, alongside diamonds, emeralds, and sapphires, rubies have held a special place in the hearts of gem collectors, royalty, and gemstone enthusiasts. However, not all rubies are created equal, and their prices can vary significantly. This article delves into the factors that make certain rubies more expensive than others, highlights some of the most valuable rubies in the world, and provides insights into the intricate market of ruby valuation.
Understanding Ruby Quality
To comprehend why some rubies command astronomical prices, it is essential to understand the key factors that determine ruby quality. These factors include color, clarity, cut, carat weight, and origin.
Color
Color is the most crucial factor in determining a ruby’s value. The ideal ruby color is often described as “pigeon’s blood,” a term that refers to a pure, vibrant red with a hint of blue undertone. This color is considered the most desirable and is typically found in rubies from Burma (Myanmar). Rubies with this coloration can fetch the highest prices. Lesser-valued rubies may exhibit brown, orange, or purple hues.
Clarity
Clarity in rubies refers to the presence of inclusions or internal flaws. While inclusions are common in rubies, fewer and less visible inclusions increase the gemstone’s value. However, some inclusions can create desirable effects, such as asterism (star-like patterns), which can make star rubies particularly valuable. Inclusions that impact transparency or disrupt the stone’s color significantly reduce a ruby’s value.
Cut
The cut of a ruby affects its brilliance and overall appearance. A well-cut ruby will reflect light optimally, enhancing its color and luster. Cut also influences the stone’s shape and symmetry, both of which contribute to its aesthetic appeal and market value. An expertly cut ruby can command higher prices compared to poorly cut stones of similar quality.
Carat Weight
As with all gemstones, the size of a ruby, measured in carats, significantly influences its price. Larger rubies are rarer and thus more valuable. The price per carat increases exponentially with size, particularly for high-quality stones. A one-carat ruby with excellent color and clarity can be expensive, but a five-carat ruby of the same quality can be exponentially more costly.
Origin
The geographical origin of a ruby can greatly affect its value. Rubies from certain locations are more prized due to their superior quality and historical significance. Burmese rubies, particularly from the Mogok region, are considered the finest and most valuable. Other notable sources include Sri Lanka (Ceylon), Thailand, Vietnam, and Madagascar. Each source produces rubies with distinct characteristics that influence their market value.
The World’s Most Expensive Rubies
Several rubies have gained fame not only for their exceptional quality but also for the record prices they have fetched at auctions. Here are some of the most notable and expensive rubies in the world:
The Sunrise Ruby
The Sunrise Ruby is widely regarded as the most expensive ruby ever sold. This 25.59-carat Burmese ruby fetched an astonishing $30.42 million at a Sotheby’s auction in Geneva in 2015. The gemstone’s exceptional “pigeon’s blood” color, combined with its impressive size and clarity, made it a record-breaking sale. The Sunrise Ruby’s price translates to over $1.18 million per carat, reflecting its extraordinary rarity and desirability.
The Graff Ruby
The Graff Ruby, a 8.62-carat Burmese ruby, is another record-setting gemstone. This ruby sold for $8.6 million at Sotheby’s in 2014, equating to $1 million per carat. The Graff Ruby’s vivid red color and high clarity contributed to its exceptional value. Laurence Graff, a renowned jeweler, purchased the ruby, further cementing its status as one of the most valuable rubies in the world.
The Hope Ruby
The Hope Ruby, weighing 32.08 carats, is one of the largest and most famous Burmese rubies. It sold for $6.74 million at Christie’s in Geneva in 2012. This ruby’s significant size, combined with its rich red color, made it a highly sought-after gemstone. The Hope Ruby exemplifies how size, color, and origin can culminate in a highly valuable piece.
Factors Influencing Ruby Prices
Beyond the intrinsic qualities of color, clarity, cut, carat weight, and origin, several other factors influence the market price of rubies. These include historical significance, market demand, and treatment processes.

Historical Significance
Rubies with historical significance or those that were once owned by royalty or celebrities often command higher prices. Provenance can add a layer of allure and prestige, making such rubies highly coveted by collectors and investors.
Market Demand
The demand for rubies fluctuates based on market trends, economic conditions, and consumer preferences. In recent years, there has been a growing appreciation for colored gemstones, including rubies, driving up prices. High demand coupled with limited supply of top-quality rubies results in higher market prices.
Treatment Processes
Many rubies undergo treatment processes to enhance their appearance. Common treatments include heat treatment to improve color and clarity and fracture filling to enhance transparency. While treated rubies can still be valuable, untreated rubies of high quality are far more rare and desirable. The presence or absence of treatments plays a significant role in determining a ruby’s price.
Investing in Rubies
For investors, rubies offer a unique opportunity to diversify their portfolios with tangible assets that have historically appreciated in value. Here are some considerations for investing in rubies:
Quality Assessment
Investors should seek rubies with the highest possible quality within their budget. Prioritizing color, clarity, and origin can lead to better long-term value. It is advisable to work with reputable gemologists or jewelers who can provide certification and assurance of the gemstone’s quality.
Provenance and Documentation
Documentation of a ruby’s origin, treatment history, and previous ownership can add significant value. Investing in rubies with well-documented provenance and certification from recognized gemological laboratories, such as the Gemological Institute of America (GIA) or the Swiss Gemological Institute (SSEF), is recommended.
Market Trends
Staying informed about market trends and demand can help investors make strategic decisions. Tracking auction results, industry reports, and economic indicators can provide valuable insights into the ruby market.
Conclusion
Rubies are among the most captivating and valuable gemstones, with prices influenced by a combination of color, clarity, cut, carat weight, and origin. The most expensive rubies in the world, such as the Sunrise Ruby and the Graff Ruby, exemplify how these factors converge to create extraordinary value. For those looking to invest in rubies, understanding the nuances of ruby quality and market dynamics is essential. By prioritizing high-quality stones with excellent provenance and staying informed about market trends, investors can make informed decisions and potentially benefit from the enduring allure and value of these magnificent gemstones.
