Fancy Pink Diamond
Origin: Australia (Argyle, closed), Brazil, South Africa
What Makes It Special
Pinks are the second rarest fancy colored diamonds after reds. What makes them so special now is scarcity—the legendary Argyle mine in Australia produced over 90% of the world's supply and closed permanently in 2020. Argyle pinks have a distinct, warm, bubblegum-to-rose hue that stands apart from the typically brownish-pinks found elsewhere. The supply shock is real.
Required Documentation
A GIA report is absolutely essential to confirm natural origin versus an HPHT or irradiated stone. Argyle stones carry their own distinct certificates and laser inscriptions which justify a massive 20-30% premium.

⚠️ HPHT limits structural color. HPHT-treated pinks are available, but their value is fundamentally disconnected from natural pinks. Do not confuse the two.

Dealer's Notes
Modifiers heavily dictate price. 'Purplish Pink' is desirable; 'Brownish Pink' trades at a substantial discount. Seek pure pinks or purplish overtones.
Argyle provenance is a standalone asset class. An Argyle laser inscription and matching Argyle dossier adds 20-30% in value instantly over a non-Argyle pink of identical GIA specs.
Color concentration is everything. A 0.50ct Fancy Vivid Pink will usually eclipse a 2.00ct Faint or Light Pink in total value. Density of color drives the market.
Check for clarity characteristics. Pinks, especially Argyles, are notoriously included due to their violent geological formation. Don't be turned off by an SI clarity if the face-up pink is potent.
Due to the Argyle closure, even 0.05ct-0.10ct melee diamonds with intense pink color are soaring in price. They make exceptional halo settings.
