Difference between old mine cut and old European cut diamonds.

Old mine cut diamonds and Old European cut diamonds are two popular diamond cuts that were commonly used in the 19th and early 20th centuries. While both are considered antique cuts, there are some differences between them.

Old mine cut diamonds were prevalent from the 1700s to the mid-1800s, and were the first type of diamond cut to have a cushion shape. These diamonds are typically squarish or rectangular with rounded corners and a high crown, a small table, and a large culet. The culet is a flat facet on the bottom of the diamond. The old mine cut diamond has a more significant sparkle with fewer facets compared to modern cuts.

Old European cut diamonds, on the other hand, were prevalent from the late 1800s to the early 1900s. They were the first diamonds to be cut with a round shape, and they have a more brilliant-cut compared to old mine cut diamonds. Old European cut diamonds have a high crown, a smaller table, and a larger overall diameter than old mine cut diamonds. They also have a smaller culet compared to the old mine cut diamond.

In summary, while both old mine cut diamonds and old European cut diamonds are antique cuts, they differ in terms of their shape, the number of facets, and the size of the culet. Old mine cut diamonds have a cushion shape with a large culet and fewer facets, while Old European cut diamonds have a round shape with a smaller culet and more brilliant facets.
