About This Stone

This 0.69 carat diamond from Gahcho Kué Mine is cut in a traditional old mine cushion, a style known for its hand-cut origins and distinctive faceting. Unlike modern brilliant cuts, old mine diamonds feature larger, more open facets that create a softer, more romantic play of light.

With VVS clarity, this stone is exceptionally clean, allowing the structure of the antique cut to take center stage. Its subtle body color adds warmth, giving the diamond a vintage character that pairs perfectly with its historic style.

Under UV light, the stone reveals a strong fluorescence, adding another layer of personality that sets it apart from standard modern diamonds.

This is a piece for those drawn to old-world craftsmanship — a diamond that feels less manufactured and more discovered.
