description Pink Diamond Overview
Pink diamonds are rare fancy-color diamonds whose hues can range from faint blush tones to stronger pink, sometimes with purple or orange modifiers. Their color is generally associated with distortion of the crystal structure rather than boron impurities. The former Argyle mine in Australia is closely linked with their history, although pink diamonds are not exclusive to that source. Color strength and size contribute to how an individual stone is valued, alongside clarity and the quality of its cut.
Their rarity has made them objects of collecting and high-value jewelry, with prominent examples connected to wealth and royal collections. Pink diamonds interest gem enthusiasts studying unusual color formation and collectors who value individual appearance. Rarity alone does not establish a stone's quality or make it a guaranteed investment.
help Pink Diamond FAQ
What causes the pink color in pink diamonds?
Unlike many other colored diamonds whose hues come from chemical impurities, the pink color is caused by a rare deformation in the diamond's crystal lattice. This plastic deformation occurred millions of years ago due to intense heat and pressure deep within the Earth's mantle during the stone's journey to the surface.
Where are most pink diamonds mined?
Historically, the vast majority of the world's high-quality pink diamonds have come from the Argyle diamond mine in Western Australia, operated by Rio Tinto. The Argyle mine was responsible for about 90% of the world's pink diamond supply until its closure in 2020.
What is the most famous pink diamond in the world?
One of the most famous is the Pink Star diamond, a massive 59.6-carat, flawless, fancy vivid pink gemstone. It set a world record when it sold at a Sotheby's auction in 2017 for approximately $71.2 million to Chow Tai Fook Enterprises.
Are pink diamonds a good investment?
Due to their extreme rarity, pink diamonds have historically maintained high value and strong investment appeal. The closure of the Argyle mine in 2020 has further constrained global supply, leading many experts to anticipate increased value for existing high-grade stones.
