Ruby is technically classified as a sapphire due to its composition. Both rubies and sapphires belong to the corundum family, with the key distinction being their chromium content—the element responsible for the ruby's striking red hue. When the chromium content is sufficient, it results in a ruby; insufficient amounts yield a sapphire. This color differentiation is what defines the category of these gemstones.
Historically, rubies were considered more valuable than diamonds. In both ancient India and medieval Europe, the unique ruby characteristics led people to believe that these gemstones contained an inner fire, elevating their status above all other gems, including diamonds.
Interestingly, many gemstones labeled as 'rubies' throughout history are not true rubies at all! Prior to the advent of modern gemological testing, numerous 'rubies' found in royal collections were actually spinels, which are notably less valuable. This includes the well-known Black Prince’s Ruby in the British Crown Jewels, showcasing how gemstone rarity can sometimes be misleading.
8/10 Fine-quality rubies (especially Burmese) are exceptionally rare. Large, clean rubies over 3 carats are rarer than diamonds of the same size.
9/10 Top-tier rubies can exceed £1,000,000 per carat. Prices rival, or even surpass, blue diamonds at the highest level. The Estrela de Fura, a 55.22-carat Mozambican ruby, sold for £28 million in 2023.
Rubies are members of the corundum mineral family. They are composed of crystalline aluminium oxide (Al₂O3), the same as sapphires!
Rubies are formed under intense heat and pressure deep within the Earth’s crust. Their formation is a particularly rare geological event as it requires an environment rich in aluminium, but low in silica and iron.
The earliest recorded usage of rubies was in ancient India, 200 BC. They're referred to in ancient Sanskrit texts under the name 'Ratnaraj', or King of Gems. Rubies were believed to protect warriors in battle, guaranteeing rebirth as an emperor.
This makes ruby one of the earliest documented gemstones in human history.

Myanmar (Formally Burma) – The Mogok Valley is historically recognized as the most prized source of rubies, renowned for its deep red 'pigeon blood' rubies, which exemplify the pinnacle of gemstone rarity and are considered the most valuable and desired quality.
Mozambique – Discovered in 2009, the Montepuez Ruby Mine has quickly become one of the most significant modern ruby deposits, arguably the second most valuable in the world.
Sri Lanka (Ceylon) - The Ratnapura region is known for producing lighter-toned, pinkish-red rubies with unique ruby characteristics that distinguish them from other sources.
Thailand – Historically, Chanthaburi and Trat served as crucial hubs for trading and heat treatment, a process used to artificially enhance the color and clarity of rubies, further establishing their ruby trade.
Madagascar – Andilamena is celebrated for its vibrant ruby colors, although the clarity can be variable and often unreliable, impacting the overall quality of the gemstone.
