Few gemstones command attention the way a fine ruby does. Deep, saturated, and burning with an inner fire that no other stone can replicate, the ruby has adorned the crowns of emperors, graced the fingers of queens, and glittered under the lights of the world's most glamorous events. To understand why rubies have captivated humanity for millennia — and why they remain one of the most coveted gemstones on Earth today — is to trace a story of power, beauty, and desire across continents and centuries.
The Sunrise Ruby: The Most Expensive Coloured Stone Ever Sold
In May 2015, a 25.59-carat Burmese ruby ring by Cartier shattered every record at Sotheby's Geneva, selling for CHF 30.3 million — approximately USD 30 million. Named the Sunrise Ruby, it was described by gemmologists as one of the rarest rubies ever seen: a pigeon's blood stone of extraordinary size with no indications of heat treatment. The GRS certificate confirmed its Burmese origin, and bidders from around the world competed fiercely for ownership.
The Sunrise Ruby remains the benchmark by which all other rubies are measured. Its sale cemented the fact that per-carat, the finest rubies now routinely outprice the finest diamonds — a reality that the gemstone trade has watched with astonishment and excitement.
Royal Rubies: Crowns, Tiaras, and State Jewels
The British Royal Family's collection includes several spectacular ruby pieces, most notably the Burmese Ruby Tiara commissioned for Queen Elizabeth II in 1973. Set with 96 rubies gifted by the people of Burma (now Myanmar) as a wedding present in 1947, the tiara holds deep personal and diplomatic significance. The rubies were chosen not only for their beauty but for a cherished Burmese belief that rubies offer protection against illness — making the tiara both an adornment and a talisman.
The Timur Ruby, a 352.5-carat uncut red spinel long believed to be a ruby, sits in the Royal Collection and bears the inscribed names of the Mughal emperors who owned it before it was presented to Queen Victoria. While technically a spinel, its history illustrates how rubies and the finest red stones have always been synonymous with sovereignty and absolute power.
Hollywood and the Red Carpet: Rubies in the Spotlight
Beyond royal vaults, rubies have long been the stone of choice for those seeking maximum impact on the world stage. Elizabeth Taylor, one of history's great gemstone collectors, owned several exceptional ruby pieces including a suite of Burmese rubies set by Van Cleef & Arpels that she wore on multiple memorable occasions. Her eye for color was legendary, and she understood intuitively that a fine ruby — vivid, alive, and unapologetically bold — speaks louder than any other stone.
In more recent years, rubies have appeared frequently on the red carpet worn by figures including Angelina Jolie, Rihanna, and Cate Blanchett. The stone's ability to photograph brilliantly under artificial light, combined with its rarity and romantic symbolism, makes it a perennial favourite for stylists seeking a piece that will define a moment.
What Makes a Ruby Truly Exceptional
The most celebrated rubies in history share several characteristics that collectors and connoisseurs prize above all else. The first is origin: Burma (now Myanmar), and specifically the Mogok Valley, produces rubies of a colour described as "pigeon's blood" — a pure, vivid red with a faint blue undertone and exceptional fluorescence under ultraviolet light. Mogok rubies are the standard against which all others are judged, and a GRS or Gübelin certificate confirming Mogok origin adds significant value.
The second is treatment status. The finest rubies are unheated, meaning their colour is entirely natural and no heat has been applied to improve clarity or saturation. An unheated Burmese ruby of good size is extraordinarily rare, and prices reflect this. For buyers seeking beauty at a wider range of price points, heated rubies from reputable origins — Burma, Mozambique, or Thailand — offer outstanding colour with full gemological transparency.
At Thai Gems, rubies are sourced with the same rigorous standards applied to the finest sapphires: direct supply chains, full treatment disclosure, and gemological certification from internationally recognised laboratories. With over 70 years in the Bangkok gem trade, the team understands exactly what separates a memorable ruby from a truly historic one.
Owning a Piece of That Legacy
You do not need to bid at Sotheby's to own a ruby of genuine quality and beauty. The same characteristics that define the world's most famous rubies — origin, colour, clarity, and treatment status — apply equally to stones at every price level. A 1-carat unheated Burmese ruby of pigeon's blood colour, properly certified, is a treasure that will hold its value and its beauty for generations.
Whether you are commissioning a bespoke ruby ring, searching for a meaningful gift that carries the weight of history, or building a personal collection of fine coloured stones, the ruby rewards those who seek it out.
