It was very popular in the early 18th century and had been around for some time before. The old mine cut had something of a renaissance in Victorian time and is still in demand today.

The level of demand is enhanced by there being relatively few good examples around. The name is, in itself, potentially misleading.

Before Africa became the diamond center we know today, most diamonds came from India or Brazil. Once it was realized that Africa did indeed have colossal diamond deposits, it quickly eclipsed the rest of the world in terms of volumes produced.

Because of that, diamonds which preceded the new era were said to be from the old mines old miners cut. The term is more broadly applied now, with the country of origin not being so important as age, cut and cutting method.

All diamonds which have come to market for the first time in the past 20 years are likely to have been laser cut.

At the very least they will have been precision-machine cut. The beauty, literally and figuratively, of old mine cut diamonds is that they were all hand cut.

Anything that is hand produced, as opposed to mass-produced, has one fantastic benefit. Every single one of them will be unique, regardless of how good or how consistent the maker was.

The same is true of the old European cut. It would be a fair assumption that most old mine cut diamonds have been lost to time. Unfortunately, all too many old diamonds vanish because of our obsession with modernization.

Before any actual mining even takes place, prospectors need to locate the diamond sources first. Geologists do this by following the trail of secondary diamond sources e.

Once the pipes are found, ore samples are examined to evaluate suitability and profitability in mining. If the presence of diamonds is proven true and profitable, shanks are inserted into the ground at the ore-bearing pipes and huge amounts of soil are extracted.

To make mining efficient and effective, the raw rock and soil are typically not examined on-site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted.

Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.

Even after extraction, the rough diamond is still far from being set in an engagement ring. In heavily secured facilities, rough stones are sorted into various gem-quality categories and industrial-specific grades.

Thereafter, the roughs are sold, cut, polished and commercialized. As you can imagine, the journey a rough diamond undergoes from its violent formation process to being mounted on an exquisite setting is a long process and passes through many different channels.

Another mining method that is frequently used is called alluvial mining. This type of mining is usually performed in areas of secondary deposits like riverbanks, beaches or even off-shore locations.

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank.

Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond-rich depth is reached, the raw material extracted from the ground is then transported to a special screening plant for further processing.

In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud. In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor.

Compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area.

Optical knowledge was in its early stages, and Antique Diamonds transport us back to this time. For instance, Diamonds cut to stand out during candlelight events in feudal times.
