What is a pink diamond?
Pink diamonds are unlike other fancy colors because their color is derived from a compounding element. For example blue diamonds get their color from boron presence, yellow with nitrogen presence. Pink diamonds happen when there is a mis-alignment in the carbon make up in general terms, caused by immense pressure and heat over millions of years creating a deformation in the diamonds crystal lattice. Pink diamonds are commonly found in the Golconda mine in India which produces Type I and Type IIa/b diamonds. As well as Brazil, south africa, Russia, and Diavik mine in Canada. Most famously, most consistent, and the biggest supply of pink diamonds came from the Argyle Mine in Australia which recently shut down in December of 2020.
Why are pink diamonds so rare?
Pink diamonds are exceptionally rare due to the geological conditions that create their unique color. Unlike other diamonds, pink diamonds are formed deep within the Earth's mantle where immense pressure and heat cause the crystal lattice of carbon atoms to distort. This distortion is what imparts the pink color to the diamond, as it absorbs light in the green part of the spectrum. The rarity of pink diamonds is further exacerbated by the fact that only a small percentage of diamonds exhibit this pink hue during their formation process, making them a true natural wonder. Additionally, the limited number of mines around the world where pink diamonds are found adds to their scarcity, with the Argyle mine in Australia, which was one of the primary sources of pink diamonds, having closed in 2020, further driving up their rarity and value.

Also important to note it is also common to see purple-pink for example, meaning there is a stronger presence of purple in the diamond than the GIA grading of purplish.
Origin: Sometimes, the GIA will provide information on the origin of the pink diamond, which can impact its value. Certain sources, like the Argyle mine in Australia, are known for producing highly sought-after pink diamonds. The GIA will also include origin if its a Type I or Type IIA diamond.
The combination of these factors determines the overall grade of a pink diamond, which can range from “Faint Pink" to "Fancy Vivid Pink," with "Fancy Vivid Pink" being the most valuable and coveted grade due to its intense color saturation and exceptional beauty.

Over 37 years, the mine produced more than 875 million carats of rough diamonds, making Australia the world's fourth-largest diamond-producing country. The mine's fame lies in its rare and valuable pink and red diamonds, with the Argyle diamond being the most renowned among them. Even though only .1% of the mines annual output, fell under the classification of pink diamonds.
In 1996, the Argyle Pink Jubilee diamond, one of the largest pink diamonds ever discovered, weighed 12.76 carats and sold for over $10 million.
