Old mine cushion lab grown diamonds vary in how noticeable their high crown and large culet are, with more dramatic proportions delivering a more historically accurate look overall and more moderate proportions offering a slightly more contemporary take on the same basic style. Buyers can lean toward either extreme depending on how much of a statement they want the stone’s history to make.
Cutting a genuine lab grown old mine style requires deliberately working against many of the proportion standards used in modern diamond cutting today, which takes a cutter with specific expertise in historical techniques. That specialized skill, together with carat weight and clarity, shapes the cost of a lab diamond finished this way.
Buyers should expect noticeably less overall sparkle from an old mine cushion compared to a modern brilliant cut, since the deep pavilion and small table were never intended to maximize fire the way contemporary faceting styles do. The large culet common to this style, essentially a small flat facet at the very bottom of the stone, is a deliberate historical feature rather than a flaw.
Pairing an old mine cushion lab diamond with a setting from a matching historical era, such as Victorian or Edwardian-inspired detailing, creates the most cohesive finished look, since mismatched design periods can feel visually disjointed. Because this style prioritizes historical accuracy over modern brilliance standards, buyers should approach it expecting a genuinely different visual experience.
Sourcing a well-executed old mine cushion lab diamond takes patience, since relatively few cutters specialize in this particular historical style compared to the many working in more standard modern proportions. That said, the wait is often worthwhile for buyers who specifically want this level of historical authenticity rather than a contemporary approximation of it.

An old mine cushion lab diamond has a soft, squarish outline, a small table, and a deep base, built by hand in the seventeen and eighteen hundreds. A larger, visible culet at the center rounds out that old look.
The deep base and oversized facets on this cut send back warm bursts of color rather than one steady, crisp sparkle. Candlelight and warm lamp light tend to bring out the richest glow in an old mine cushion lab grown diamond.
