1. The historical and cultural value of diamonds cut from old mines

In addition, old mine-cut diamonds also have a certain sense of mystery and romance. In the late 18th and early 19th centuries, gems and jewelry were often viewed as mysterious and luxurious items that could only be owned by the upper classes. Therefore, old mine-cut diamonds were considered an extremely precious item at the time, representing a symbol of wealth and status.

2. The unique features of diamonds cut from old mines

Old mine cut diamonds differ from modern brilliant cut diamonds in the way they are cut and in the proportions of their cuts. Old mine cut diamonds usually have fewer facets, most of which are at the base of the diamond. This means that light cannot reflect from multiple facets, creating an intense sparkle effect, as it does in modern brilliant-cut diamonds. Instead, light only reflects from a few facets, giving the diamond a softer luster.

Additionally, the proportions of old mine-cut diamonds are different from those of modern brilliant-cut diamonds. Old mine-cut diamonds typically have a smaller diameter-to-depth ratio, meaning they have a deeper base and a larger table. This cut makes the diamond look thicker from the side, but it also affects the diamond's optical properties. Smaller cut proportions prevent light from reflecting inside the diamond, reducing the diamond's sparkle and luster.

3. The rarity of old mine-cut diamonds

Old mine cut diamonds are rarer than modern brilliant cut diamonds due to their ancient cutting method and historical value. Many old mine-cut diamonds have been collected by jewelers and collectors, so their supply is very limited. Furthermore, over the past few decades, due to technological advancements and market demand, few jewelers continue to use old mines to cut diamonds. As a result, there are fewer old mine-cut diamonds, which keeps their value rising.

4. Price of diamonds cut from old mines

Due to the rarity and historical value of old mine cut diamonds, they are generally more expensive than modern brilliant cut diamonds. The price of old mine-cut diamonds has been rising over the past few decades. For example, in 2018, Christie's auction house sold a 4.19-carat old mine-cut diamond for a final price of $1,325,000. Modern brilliant-cut diamonds of the same size and quality typically cost less than $1 million.

However, the price of old mine-cut diamonds also depends on their quality and characteristics. Old mine cut diamonds, like modern brilliant cut diamonds, come in a variety of colors, clarity, and cut qualities. High quality old mine cut diamonds will generally be more expensive than lower quality old mine cut diamonds.

Although the sparkle and luster of old mine-cut diamonds are not as good as modern brilliant-cut diamonds, they represent the cultural and historical heritage of an era and therefore have collection and investment value.
