Vintage Engagement Ring with Emerald-Fancy Gray and Argyle Pink Diamond Ring, 3.02 Carats
Qty:
Diamonds with a gray hue are exceedingly rare, forming over millions of years through exposure to hydrogen deep within the earth. Gray diamonds of richer, more vivid shades like this one are significantly rarer than their lighter counterparts. Achieving the depth and saturation necessary for a fancy gray grade is exceptionally uncommon, making this diamond a remarkable find.
The Argyle diamond mine in Western Australia, active from 1983 to 2020, was famed for its rare pink diamonds, representing just 0.1% of its production. These diamonds, prized for their unique hues, have shown consistent value appreciation, often outperforming major markets. With the mine's closure, Argyle diamonds have become even more coveted, bolstered by exclusive sales events and dwindling inventory.
