There's a reason old mine cut engagement rings have been on our radar so much recently, and the history of it explains exactly why. This diamond predates the round brilliant by two hundred years, faceted entirely by hand, stone by stone, long before a laser ever touched a diamond. That's precisely why so many old mine cut rings on the market right now are one of a kind: no two cutters worked a rough diamond identically, so the asymmetries and oversized, irregular facets are its signature element. These stones tend toward a rounded square or rectangle rather than a perfect circle—the direct ancestor of the cushion cut—while the fully round version of this era belongs to its relative, the Old European cut. What that softer silhouette does give you, alongside a higher crown and a large culet, is a chunkier, warmer sparkle that reflects especially well under candlelight.
Few of these stones survived in wearable condition, so tracking one down typically means working through estate dealers and independent sellers instead of a standard inventory. If vintage-style rings are your thing, we can assure you that every ring on this list carries its own two-hundred-year backstory, ensuring no two rings are exactly alike. Ahead are the old mine cut engagement rings we can't stop staring at, sourced from vintage jewelry shops and both well-known and up-and-coming jewelers alike—including a few modern settings built specifically around these special antique stones.
