Old Mine Cut
The old mine cut is the cushion-shaped diamond of the Georgian and Victorian eras — squarish, high-crowned and full of warm, candlelit life.
What is an old mine cut?
The old mine cut is an early brilliant with a soft, squarish 'cushion' outline, a high crown, a small table and a large open culet. Cut entirely by hand in the 18th and 19th centuries, each stone follows the rough crystal, so no two are identical.
History & why it matters
It is the forerunner of the old European cut and the modern brilliant, and is the classic diamond of Georgian and Victorian jewellery. Collectors prize its hand-cut character and warm glow.
How to identify & what affects value
Look for a cushiony, slightly uneven outline, a tall profile and a visible culet. As with all antique diamond cuts, an original stone in its period mount is worth more than a recut one. Read more on gemstone cuts.
