Lab Grown Old Mine Cut Diamonds

Old Mine Cut diamonds have a squarish cushion shape, high crown, small table, and large facets that produce a softer, warmer sparkle, often described as candlelight-like. Modern cuts, such as the round brilliant, feature more symmetrical proportions and reflect sharper, whiter light.

Look for key features such as a slightly square shape, deep pavilion, high crown, small table, and an open culet. These characteristics distinguish the Old Mine Cut from other antique and modern cuts like the Old European or round brilliant.

Absolutely. Just like mined diamonds, lab grown Old Mine Cuts are available in a variety of colour grades, from near colourless to fancy hues like yellow or pink — offering options for every personal style.

An old mine cut has a squarish, cushion-like outline with rounded corners, while an old european cut is fully round. Both share a high crown, deep pavilion, and large culet, giving them a similarly warm, antique sparkle.

SI1-SI2 clarity is usually eye clean, since the cut’s deep pavilion naturally hides inclusions. For color, H or higher gives a bright, clean look, while I-J suits those wanting a warmer, more antique tone.

Vintage solitaires, bezel settings, and halo designs are traditionally favored, as they frame the cut’s cushion-like silhouette and antique character without overpowering its soft glow.

Old mine cut diamonds can range from a more square, cushion-like outline to a softer, more rounded rectangular shape, depending on the original stone and cutting style. Each stone’s exact outline varies slightly, which is part of its antique charm.

An old mine cut shows broader, warmer flashes of light with more visible facets at rest, while a modern cushion cut is engineered for brighter, more consistent scintillation under varied lighting.
