Gleaming with vibrant colors and a rich, fascinating story woven into its history, spinel is a gemstone that has long captivated jewelers, collectors, and royalty. Often overshadowed by rubies and sapphires, spinel holds a unique place in gemstone lore. Once mistaken for some of the most valuable gems in history, spinel earned the nickname “The Great Impostor.” This article delves into the captivating world of spinel, exploring its striking beauty, its role in the history of red stones, and its resurgence as a highly sought-after gemstone in today’s market.
What is Spinel?
Spinel is a natural gemstone composed of magnesium aluminum oxide. Its crystal structure forms in the cubic system, making it not only durable but also brilliant in appearance. Spinel comes in a variety of colors, but it’s most famous for its vivid reds, rivaling some of the finest rubies. Other colors include pink, blue, purple, and orange, each offering unique appeal.
The name “spinel” comes from the Latin word spina, meaning thorn, likely referencing the gem’s sharp octahedral crystal shape. While it was historically mistaken for other gemstones, spinel has gained recognition for its unique charm and rarity. Its beauty, durability (with a hardness of 7.5–8 on the Mohs scale), and a wide palette of colors make it a gemstone worthy of admiration.
Spinel’s Role Among Red Stones
When conversations turn to red stones, the ruby usually takes center stage. However, spinel deserves equal recognition for its striking resemblance to ruby and its place in history. For centuries, some of the world’s most famous “rubies” were later identified as spinels.
How Does Spinel Differ from Ruby?
While spinel and ruby may look alike, they are distinct in their mineral composition. Ruby is a variety of the mineral corundum, made primarily of aluminum oxide that gets its red hue from trace amounts of chromium. Spinel, by contrast, has a different crystal structure and chemical composition.
One way to distinguish spinel from ruby is through refractive properties. Spinel has a single refractive index, whereas ruby is doubly refractive. However, with the naked eye, even seasoned gemologists were unable to tell the difference in earlier times. This is why spinel was often misidentified as ruby—a case of mistaken identity that gave rise to its reputation as “The Great Impostor.”
Historical Significance of Spinel
The history of spinel is as colorful as the gemstone itself. In ancient times, spinel was often mined in the same regions as ruby and sapphire, particularly in Southeast Asia. Without modern gemological tools, miners and royalty alike mistook spinel for ruby, incorporating it into their crowns, swords, and treasures.
Mistaken Identity – The Black Prince’s Ruby
One of the most famous examples of spinel’s misidentification is the “Black Prince’s Ruby,” a vibrant red gemstone that sits at the center of the British Imperial State Crown. Initially thought to be a ruby, this gemstone is, in fact, a red spinel.
The story dates back to the 14th century, when the Black Prince, Edward of Woodstock, received the gemstone as a gift. The massive spinel eventually became part of the British Crown Jewels, where it remains to this day. Its fiery red hue and impressive size make it one of the most iconic “rubies” of all time even though it isn’t a ruby at all.
The Timur Ruby
Another famous jewel, the Timur Ruby, is also a red spinel. Weighing an incredible 361 carats, it was once considered one of the largest rubies in existence. Like the Black Prince’s Ruby, it was eventually identified as a spinel. This gem, inscribed with the names of its former owners, including the Mughal emperors of India, carries centuries of history.
Spinel in Ancient Cultures
In addition to its ties to European royalty, spinel played a significant role in the cultures of Asia, particularly in Southeast Asia, where it was mined. Known as “balas ruby” in ancient texts, spinel was highly prized and often attributed with mystical powers, such as protection and vitality. As trade routes expanded, spinels traveled from Asia to Europe, where they adorned royal treasures.
The Resurgence of Spinel in Modern Times
For centuries, spinel lived in the shadow of rubies and sapphires, but in recent years, its value and popularity have grown dramatically. Gem enthusiasts now appreciate spinel for its vivid colors, excellent clarity, and affordability compared to other precious gemstones.
