Vintage diamonds
The Old Mine cut was the first diamond cut to consistently feature 58 facets, evolving from earlier cutting styles as lapidary techniques advanced. Its most significant predecessor was the Peruzzi cut, widely regarded as the first true brilliant-style diamond, credited to 17th-century Venetian lapidary Vincenzo Peruzzi.
The Peruzzi cut marked a turning point in diamond history, introducing a more systematic approach to faceting in order to enhance light return. Building on this foundation, the Old Mine cut refined the brilliant concept further, developing fuller facet arrangements designed specifically to maximise fire and scintillation under gas and candlelight.
Old Mine cut diamonds were shaped entirely by hand and judged by eye rather than mathematical formula. Their straight-edged outlines with softly rounded corners, high crowns, small tables, deep pavilions, and larger facets create a warm, expressive glow rather than sharp brilliance.
Recognised for its softly squared outline and romantic character, the Old Mine cut is a vintage diamond style ideally suited to those seeking an engagement ring with genuine antique or vintage presence.
What to Look for in an Old Mine Cut Diamond Engagement Ring
If you are considering an Old Mine cut diamond, there are several characteristics worth understanding:
Lighting
Old Mine cuts reveal their beauty differently depending on their surroundings. Viewing the diamond under a variety of lighting conditions allows you to appreciate its warmth, depth, and expressive play of light.
Larger, Chunkier Facets
These diamonds feature broader, more pronounced facets than modern cuts, resulting in a softer contrast pattern and a distinctly antique appearance.
Less Brilliance, More Fire
Rather than the sharp brilliance of modern round brilliant diamonds, Old Mine cuts are prized for their fire, bold flashes of spectral colour created by their larger facets. This effect is particularly captivating under spot or evening lighting, where their character truly comes to life.
