Introduction: The Allure of Pink Gemstones Pink gemstones have captivated humanity for centuries, symbolizing love, luxury, and rarity. From Elizabeth Taylor’s legendary jewels to modern celebrity engagement rings, pink diamonds and sapphires command attention. But beneath their similar blush lies a world of difference in origin, value, and science. Let’s dissect these treasures.

Pink Sapphire:

Origin & Science Pink sapphires belong to the corundum family (like rubies), deriving their color from chromium traces. Unlike rubies, they lack the iron that creates red, resulting in a spectrum from delicate ballet slipper to vivid hot pink.

Key sources include Madagascar, Sri Lanka, and Tanzania. Learn about corundum formation from the Smithsonian Institution.

Durability & Practicality

Mohs Hardness: 9/10 (second only to diamonds)

Ideal for daily wear in engagement rings.

Resists scratches better than most gems.

Market Value

1-5 carats: $800–$8,000/carat

More accessible than pink diamonds, with vibrant options at lower price points. Shop natural pink sapphires at CaratX Marketplace

Pink Diamond:

Origin & Science Pink diamonds owe their color to structural distortion during formation. Intense pressure twists their crystal lattice, bending light to create pink hues without chemical impurities. This phenomenon occurs almost exclusively in Australia’s Argyle Mine (now closed), making them exponentially rarer.

The Rarity Factor

Argyle produced 90% of pink diamonds but closed in 2020.

Only 0.1% of Argyle diamonds were graded "Fancy Vivid."

Supply depletion has spiked prices by 500%+ since 2000.
