Fancy pink diamonds: rarity, price and how to buy
Among the rarest diamonds on earth, with almost no new supply since the Argyle mine closed — how pink is graded, and what drives its price.
Pink is the colour that made fancy colour diamonds famous, and the one with the tightest supply. Since 2020, when the Argyle mine in Western Australia — the source of more than nine in ten of the world's pink diamonds — closed for good, every fine pink on the market is effectively drawn from a fixed, shrinking pool.
A colour without a chemistry
Unlike yellow (nitrogen) or blue (boron), pink comes from no impurity at all. Immense pressure deep in the earth bends the carbon lattice, and the distorted planes absorb light to leave pink, red or purple. Because it cannot be predicted from chemistry, pink has always been the least reliable colour to find — and the most prized when it appears.
Reading a pink's grade
Pinks run the full intensity ladder, from Fancy Light Pink through Fancy Intense and Fancy Vivid, with Fancy Deep for the richest tones. An overtone shifts the character and the price: a clean "Fancy Vivid Pink" sits far above a "Fancy Light Brownish Pink" or "Purplish Pink" of the same weight.
A one-carat vivid pink can outprice a flawless white many times its size.
What drives the price
- Intensity and purity carry most of the value — the step from Fancy to Fancy Intense to Fancy Vivid is where price climbs fastest.
- Origin — a natural colour origin on the report is everything; treated pinks exist and are worth a small fraction.
- Size — large pinks are extraordinarily scarce, so the per-carat rate rises sharply with weight.
Buying with confidence
Insist on a GIA, IGI or HRD report that reads natural, match its number to any laser inscription on the girdle, and view the stone in good light before you decide. Supply this tight rewards patience and a trusted source.
