The captivating appeal of pink diamonds stems from a geological anomaly, setting them apart as some of the most coveted gemstones on Earth. Unlike other colored diamonds, which derive their hues from trace elements, the distinctive blush of a pink diamond is a result of a rare structural distortion within its crystal lattice. This phenomenon occurs under immense heat and pressure deep within the Earth, displacing carbon atoms and altering the way light is refracted, thereby creating their signature color.

Historically, the earliest documented instances of pink diamonds trace back to 17th-century India, specifically the Kollur mine within the historic Golconda kingdom. From this legendary region emerged magnificent stones such as the Daria-i-Noor, a pale pink diamond of approximately 186 carats, which remains a testament to their ancient provenance. In more recent times, Australia's Argyle mine, operational from 1983 until its closure in 2020, became the preeminent source, accounting for over 90% of the world's natural pink diamond supply. While other deposits exist in locations including South Africa, Canada, Russia, and Brazil, the cessation of Argyle's operations has profoundly impacted global availability, further elevating the rarity and market value of these exceptional gems.

Evaluating these precious stones involves a meticulous process, with color being the paramount criterion. The GIA color grading scale for pink diamonds ranges from Faint to Fancy Deep, assessing hue, tone (lightness or darkness), and saturation (intensity). Medium tones are often highly prized, and secondary hues such as purplish-pink, brownish-pink, and orangy-pink add further complexity and desirability. Beyond color, clarity, cut, and carat weight are also critical factors, mirroring the standards applied to white diamonds. Given their scarcity—only about 0.01% of all mined diamonds are naturally pink—stones exceeding one carat are exceedingly rare and command significant attention from collectors. Certain cuts, including cushion, radiant, oval, and pear, are favored for their ability to enhance color and optimize the yield from the rough stone.
