The Difference Between Old Miner and Old European Cut
Old mine cuts were a product of the technology of the time. The diamonds, cut without the advantage of Motorized machinery, followed the rough diamond's octahedral shape.
Until the late 1800s, this created mostly square or rectangular cushion-shaped diamonds. The shape of the old stones of that time was not uniform at all, even thought they have the same number of facets, 58, as the modern round brilliant.
| Old Mine Cuts | Old Euro Cuts |
| Looks Square, Corners more Square Heavy crown Very large Open culet Very deep bottom Very small table Heavy, clunky look, facets not uniform |
Rounder Look Open culet, but smaller than the old miner Very small table ( usually less than 53%) More even factes on the pavilion Bottom halfs are short, only 50% of the distance from the girdle to the culet (modern is 85%) |
