The old mine cut diamond is the antique diamond cut that was prevalent from the mids until the earlys.

It is the predecessor to the modern diamond but has many elements that remain very unique and different. The old mine cut is probably the oldest recognized cut type we know today.

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.

The earliest Diamond discoveries originated in India. Diamonds in their rough form were probably used as embellishments for jewelry adornments before evidence — from around the 14th-century — revealed Indian and European abilities to grind and cut diamonds.

Prior to this, and because Diamonds were discovered in India, cleaving was the only known method for shaping rough Diamonds, and thus we can assume with a high-degree of certainty that the method originated in India.

In the beginning, cleaving was mainly developed for the shaping of irregular rough Diamonds into point cuts that were popularized in the era. A cleaver could shape almost any irregular rough form into an octahedron, which could then be adapted into a point cut.

Point cut Diamond. As cleaving continued to evolve it soon became possible to split and divide rough Diamonds along its plane directions.

This allowed the partition of a single rough crystal which cleavers took into account to avoid unwanted internal inclusions. A Diamond cleaver has only four cleavage directions, which is extremely limiting and probably the main reason for the development of the flat rose cut Diamond.

Rose cut Diamond. Describing material in this way usually meant its provenance was from a famous and probably depleted mine associated with exceptional and rare gem quality.

Examples of these Old Mines would include examples like the historical Colombian Chivor and Muzo Emerald mines that were active from the early part of the 16th-century, and the storied and legendary Burmese Mogok Ruby mines that were famous for their pigeon, blood-red colors.

The second point of direction speaks to the actual lapidary works on the gems. Rough crystals came in many forms and surface textures and were often marked with plenty of irregularities various inclusions.

In essence, they dictated the early shapes and cutting designs. Although Old Mine Cuts exist in all gem materials of the time, over time the term became primarily linked to Diamonds.

I believe the Old Mine designation begins at the antiquity age but dives mysteriously deeper into lapidary histories, which were a well-kept secret for hundreds and perhaps even thousands of years.

Old Mine Cuts came in many shapes and cuts. In fact, the shape and contour of the rough were responsible for determining the end-shape of the polished Diamond.

First came irregular shapes and faceting, and only then were naming conventions issued. Old Mine Cuts were a very wide scope of different cuts, but they all shared one key attribute — their purpose was to bring forth a strong play-of-light.

Old Mine Pear Cut Diamond. Triangular Old Mine Cut Diamond. There have been many Old Mine Cut Diamonds that made headlines throughout the years.

Here are just a few examples:. Toward the end of his life, Mazarin assembled a collection of 18 exceptional gems.

The Grand Mazarin. The Wittelsbach Diamond known presently as The Wittelsbach-Graff , is one of the earliest documented brilliant cuts.

Its history originates around midth-century. After being purchased in December by Laurence Graff, a decision was made to re-cut this historical Diamond.

This decision caused a lot of waves at the time with some people going as far as to call it an act of vandalism. The interesting story of this Old Mine Cut Diamond is possible because of my direct involvement in the early stages of this specific and rare gem.

What my eyes saw was a beautiful Together, these four things may seem like they cover everything related to diamonds or do they not? When was the last time you thought about the African people and miners who are getting their hands dirty in order for you to wear that beautiful engagement ring?

As it turns out, mining for diamonds is one of the most resource-heavy and time-consuming processes that companies have to invest their efforts in.

Even with all our technological advances and engineering tools, diamond mining still incorporates a certain level of art and science combined.

So, let us also take a look at some methods in which rough diamonds are extracted from the ground. 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.

Yep, you heard that right. Water, streams and rivers are the main drivers in the formation of secondary mining deposits as they can transport rough diamonds away from Kimberlite pipes to locations as far out as the ocean.

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.
