Antique ring made in 1878 set with a mine cut diamond
A brief history of the mine cut diamond:
At the start of the 18thÂ century, a great leap forward emerged with the â€śinventionâ€ť of the new 58-facetted diamond. At the time, these were the closest resemblance to todayâ€™s brilliant cut, and are referred to as old mine cuts, or old miners. These were cut often squarish or cushion shaped, with quite a steep angle on the crown and pavilion, to maximise weight retention. While weight was kept to a maximum, they often lacked a lot of internal fire and â€śbrillianceâ€ť. As well as these features, the â€śold minersâ€ť often had quite a large culet or â€ścolletâ€ť, the horizontal base formed by the blunting of a point when the stone is cut as a brilliant.
