Introduction
For hundreds of years, the brilliant light reflected by faceted diamonds has made them the focus of attention. The primary factor affecting the degree of diamond shine is the cutting method. Modern cutting is mostly focused on brilliant cut that highlights the brilliance of faceted diamonds. However, there are still some people who prefer old-fashioned cutting with soft and elegant light. When it comes to old-fashioned cutting, we have to mention the most classic ones, old mine cut and old European cut.
Old Mine Cut

Old mine cut was popular from the early 18th century to the late 19th century and was the most common diamond cutting style in Georgian and Victorian jewelry.

Name Origin
The name originated from the mid to late 19th century. At that time, South Africa's abundant drilling resources were being excavated. With a large amount of African diamonds being mined and flooded into the market, mines in Brazil and India, which were previously the main diamond mining areas, became "old mines", and any high-quality cutting method before that was called old mine cutting. Nowadays, the term "old mine cut diamonds" in people's minds refers to diamonds that are approximately square in shape, using the faceted arrangement that became popular in the early 18th century
Characteristic
Old mine cut diamonds have 58 facets, most of which are square, with rounded edges, small tables, high crowns, thin waist edges, and a large octagonal facet of the culet. Compared to modern brilliant cut, old mine cut diamond cutting has a larger facets, and the color blocks visible under light are also obvious, resulting in a lower degree of shine. Most of the old mine cut diamonds during the Georgian and Victorian periods were square, and were laboriously polished by early diamond cutters according to the octahedral shape of the diamond crystal, using a diamond polishing machine to polish the two diamonds together. In addition, the cutting principle of maintaining weight is adopted, and the size of the finished product is also determined by the size of the raw stone, which makes every old mine cut diamond unique.
Old European Cut

Old European cut is a round cut process that originated and flourished from 1890 to 1930. It was the mainstream diamond cutting style during the Art Deco period and the predecessor of modern round brilliant cut.
The old European cut diamond has 58 facets. Its characteristics include a high crown, fat triangular facets, a large overall depth, and a smaller and more round culet area compared to the old mine cut diamond.

The cutting process of old European cut can be said to be inherited from old mine cut. The cutting principle of old European cut was also to retain more weight, and until the mid-20th century, diamonds were manually measured and cut by craftsmen, so there were no fixed proportions and sizes, and they were far less shining than modern brilliant cut diamonds. But it also makes every old European cut diamond unique.
