Pink Diamonds

Pink Diamonds – Basics

High-quality pink diamonds command extremely high prices, second only to red diamonds – the rarest of all fancy colors. Over 90% of the world’s pink diamonds were supplied by Australia’s Argyle diamond mine, which closed in 2020, so they are only getting more valuable. Only 1 carat out of every 10,000 carats mined is a natural fancy colored diamond, making rarer colors with high saturation extremely valuable.

PriceScope Pointer: When it comes to fancy colored diamond (FCD) cutting you can throw away the normal cut-quality rules for D-Z colors. The goal with FCDs is cutting with angles that exaggerate the color present – opposite the goal for well-cut D-Z diamonds.

What are Pink Diamonds?

There is still a little mystery surrounding the cause of color in pink diamonds. The color is generally thought to be caused by colored graining, which results from structural irregularities in combination with an impurity. Distortions in the crystal structure are thought to be the cause of color for 99.5% of pink diamonds. Australia’s Argyle Diamond Mine produces most of the world’s pink diamonds, which are sold at the annual Pink Tender.

Common secondary colors in pink diamonds include brownish pink, orangish pink, and purplish pink. As is the case with all fancy color diamonds, pure pink colors are the most prized and thus the most expensive, particularly those which are heavily saturated with a rich color. Certain modifiers can create highly desirable diamonds and though more common, paler pinks are still rare and coveted in the diamond world. Natural fancy pinks are appreciably rare regardless of secondary colors and are priced accordingly.

Are Pink Diamonds Rare?

Natural, pink diamonds have been in high demand for the last two decades, and this rise in popularity has caused a rise in price. Aside from red diamonds (the rarest and most valuable fancy color), high-quality pink diamonds command the highest prices. Over 90% of the world’s pink diamonds were found in the Argyle mine, which closed in 2020, yet less than 1% of the mine’s output was comprised of pink diamonds.
