HOW THE EUROPEAN CUT DIAMOND EVOLVED FROM THE OLD MINE CUT DIAMOND
Popular in the 18th century, the bruting of diamonds became available in the industry. As a result, diamond cutters began shaping Old Mine Cut diamonds by following the octahedral shape of the diamond crystal. The cutter then meticulously ground two diamonds together to complete the desired shape. After the shape was completed, a diamond polisher would polish the facets. Dimensions varied from stone to stone because of the odd shaped diamond rough and since they were completely crafted by hand, each Old Mine Cut has its own persona/personality. They have a square or rectangular shape, more like a cushion cut, whereas the European Cut diamond has a round shape. The Old Mine Cut Diamond was the predecessor of the European Cut Diamond and the modern Round Brilliant Cut Diamonds of today. The tables on these older cut diamonds are typically smaller with higher crown angles. Old mine cuts, like the European Cut diamonds, have open facets and a culet that is also faceted. Looking inside the diamond with a jeweler's loupe, you will see what looks like a tiny circle in the center of the stone and that is the "open culet".
