Mine Cut or Old European Cut Diamonds
The old European Mine cut diamond has a smaller table, a heavy crown, and great overall depth. This diamond cut was the forerunner of the modern brilliant cut. Like the modern round brilliant, the diamond has a circular girdle. In some cuts the culet is cut off to help light to shine into the bottom of the gemstone. Then looking from the top of the diamonds table some cuts looks like a hole is through the diamond. This is not the case at all, just an illusion.

Diamonds, known for over 3000 years, were probably first found in India as loose stones associated with the sand and gravel of riverbeds For centuries they were thought to possess magical powers, no doubt because of their hardness and luster, and were kept, uncut, as sacred objects or important treasures of state by the religious and political leaders of the day. Diamonds being regarded as talisman that would lose their powers if they were altered in any way. It wasn't until the 11th century that diamonds were first worn, in their uncut form, as adornments. However, with the use of diamonds in jewelry, sometime in the 13th century it became known that grinding and polishing of the rough crystal could enhance the diamond’s appearance.
This was achieved by polishing with diamond dust at angles varying slightly from those of the original octahedral faces to form a point cut.
A major advance in faceting came about with the introduction of the polishing wheel, in the middle of the 14th century. This led the way for brighter diamonds with increased facet pattern complexity.
