In the world of exquisite gemstones, sapphires and rubies often pique curiosity with their stunning array of colors. If you've ever wondered about the hues of these natural beauties, let's delve into a simplified explanation of how sapphires acquire their mesmerizing colors and differentiate them from rubies. While I won't delve into technical details, I'll offer a concise glimpse into this captivating process.
Both sapphires and rubies belong to the corundum family, encompassing a spectrum of colors. Interestingly, all colors of corundum except red are classified as sapphires.
At its core, corundum is composed of aluminum oxide (Al2O3), rendering it colorless – the basis of a sapphire. The infusion of additional elements or impurities into this foundation creates the breathtaking range of sapphire colors we admire.
For instance, a blend of titanium and iron within the corundum structure gives birth to the mesmerizing blue sapphire. On the other hand, the presence of chromium impurities results in the vibrant red of a ruby. The varying shades of pink to red within rubies stem from the quantity of chromium present.
When chromium coexists with other elements in a blue sapphire, it metamorphoses into a captivating purple hue. Yellow sapphires, intriguingly, obtain their color through various methods. While I won't delve into the complexity of these methods, the primary contributor is iron. Green sapphires, while rare, also owe their color to iron. Notably, green sapphires are less prevalent due to their scarcity.
Interestingly, iron emerges as a common factor responsible for the captivating blue, yellow, and green hues in sapphires. It's worth noting that the majority of Australian blue sapphires tend to possess a subtle greenish undertone, largely attributed to higher iron content.
Beyond the realm of color, sapphires across all shades share similar properties, including hardness and durability.
