If you’re searching for something romantic, soulful, and unlike any modern diamond cut, old mine cut diamond engagement rings deserve a place on your radar. Famously known as “candlelight diamonds,” old mine cuts were developed in the 18th and 19th centuries, long before electricity, when diamonds were viewed under candlelight and gas lamps. Cutters intentionally shaped them with high crowns, smaller tables, deeper pavilions, and open culets to maximize soft, flickering light. Instead of the sharp, white brilliance of modern round diamonds, old mine cuts produce broader flashes of fire and a warm, glowing depth that feels almost alive in low light, a quality that earned them the enduring nickname, candlelight diamonds.

10. Astrid 1.58

Authentic antique old mine cut diamond engagement rings are most often found set in yellow gold, sometimes with silver-topped settings typical of the 19th century. In our vintage-inspired By Erstwhile designs, we typically pair old mine cut diamonds with yellow gold, as the warmth of the metal complements the softer tones these stones often carry. However, the I color of this particular old mine cut is notably white, making it exceptionally well suited to platinum — as seen in the Astrid 1.58, where the cooler metal enhances its brightness and clarity.
What Makes an Old Mine Cut Diamond So Special?
Old mine cut diamonds are not just another historical style, they’re a living snapshot of craftsmanship from long before computer precise cutting became standard. Each stone was cut by hand, shaped to reflect the light sources of its era — candlelight, oil lamps, and early daylight — giving it a warmth and fire unlike modern rounds. (Source: GIA)
