Rare 37-Carat Pink Diamond Found in Botswana Mine

In a remarkable discovery, miners in Botswana have found a 37.41-carat diamond that displays a rare combination of pink and colorless hues — a gem experts describe as both unique and scientifically significant. The find was confirmed by the Gemological Institute of America (GIA), which called it “astounding” for its size, clarity, and unusual two-tone […]

Rare 37-Carat Pink Diamond Found in Botswana Mine

Miners in Botswana have unearthed a rare 37.41-carat diamond displaying a captivating combination of pink and colorless sections. This remarkable find offers new insights into the formation of such unusual gems, according to experts at the Gemological Institute of America (GIA). The diamond, roughly the size of a small grape, measures approximately 24.3 millimeters in length and presents a clear split between a vivid pink portion and a transparent, colorless zone.

Researchers believe the striking two-tone appearance indicates the diamond underwent two distinct stages of formation deep within the Earth's crust. Scientists at the GIA explain that the pink section likely originated as a colorless crystal that underwent a transformation due to immense underground pressure, gradually adopting its pink hue.

Conversely, the clear portion formed later under more stable geological conditions, preserving its colorlessness. This unique two-stage formation process is exceedingly rare in nature, providing a valuable window into the forces shaping Earth's inner layers. Sally Eaton-Magaña, a senior scientist at the GIA, notes that minor atomic disturbances during diamond creation can produce color changes.

In this instance, the pressure was sufficient to impart a pink tint to the gemstone, yet not so intense as to result in a brownish hue, which is more common in similarly pressured diamonds. Botswana has long been a premier destination for gem discoveries, with the Karowe mine in particular renowned for producing some of the world’s largest and most valuable diamonds.

Operated by Lucara Diamond Corporation, the mine has already yielded noteworthy finds, including a massive 2,488-carat stone and a 62-carat pink diamond. This newly discovered diamond's exceptional size and distinct color division distinguish it as one of the most remarkable examples of its kind ever recorded. Botswana's continued prominence in the global diamond industry underscores the country's abundant natural resources and the awe-inspiring geological processes that give rise to these extraordinary and exquisite gems.
