A little something about old mine cut diamonds:

From the early 18th century to the late 19th century, the old mine cut was perhaps the most common diamond cut and the cut you’ll most often find in Georgian (1714-1837) and Victorian era (1837-1901) jewelry.

You can recognize an old mine cut diamond by its squarish shape: it has 58 facets like today’s modern round brilliant cut diamond, but that’s where the similarity ends.

In addition to a different shape, an old mine cut has different diamond proportions: it typically has a smaller table, larger culet and higher crown. It also has short lower half facets and a girdle that is very thin in places and, as a result of these factors, an old mine cut diamond has a very distinctive look.

Early diamond cutters (today known as bruters) shaped old mine cut diamonds by following the octahedral shape of the diamond crystal, laboriously grinding two diamonds together to achieve the desired shape, and a diamond polisher then polished the facets. Due to the shape of the rough and because the diamonds were hand crafted, dimensions varied from stone to stone. This made every old mine cut diamond unique, or put poetically, have its own personality.
