What is the Old Mine Cut Diamond?

January 30, 2018 – Posted in: Jewelry Blog

The jewelry industry is packed with lots of words that have so much context that requires explanation. The old mine cut diamond is one fantastic example.

In this article we are going to explore what is the old mine cut and what makes it so special and unique.

What is the Old Mine Cut Diamond?

The old mine cut diamond is the antique diamond cut that was prevalent from the mid-1800s until the early-1900s. It is the predecessor to the modern diamond but has many elements that remain very unique and different.

It’s most notable features are the bulky uneven shape, the eye-visible culet, and the tiny table.

As with almost everything, “old” and “new” is relative. If we class the Great Pyramid of Giza as “old”, then even the castles of medieval England can be classed as “modern” despite some being nearly 1000 years old. With diamonds the descriptions don’t cover quite such a period but, with old mine cuts, we are talking about diamonds being cut up to 300 years ago.

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.

How Many Old Mine Cuts Still Exist?

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. Loss, theft, damage and more does take its toll, but that’s not the whole truth. Unfortunately, all too many old diamonds vanish because of our obsession with modernization.

Because of the slightly “rustic” appearance of old mine cut diamonds, and the modern penchant for round cuts, a lot have been re-cut in the intervening decades. The aim was to make them more appealing to a marketplace which demanded ever “cleaner” diamonds. Thankfully, in the past decade or so, this trend has reversed, with old mine cut diamonds becoming ever more popular, and very saleable in their original state.

As we gratefully start to move out of the bling era, the age of subtlety and understatement is beginning to take shape. Old mine cut diamonds are more desirable than ever, and their unique light reflecting properties treasured.

The Old Mine Cut In Detail

When we talk about old mine cuts, it’s usually thought of as the classic old mine almost-square shape. Producing round diamonds by hand is incredibly difficult, even for the best cutters, and so a more cushion-type appearance was used. The basic finished cut is similar to modern diamonds only in that it incorporates the same elements. From top to bottom, as with other cuts, there is a table, crown, girdle, pavilion, and culet. Again like modern cuts, there are 58 facets on an old mine cut diamond.

The differences, once we accept the underlying physical similarity, are quite pronounced. An old mine cut will have very different proportions to more modern cuts. There will be a smaller table with a higher crown and a larger culet. The girdle can often be inconsistent, and very thin in places.

Although we do tend to think of old mine cut diamonds as square-ish, there are several other cuts which qualify. Genuine antique cushion, emerald, Asscher and marquise cuts all come under the banner of old mine cuts.

By grinding two diamonds together, and then polishing each stone individually, each old mine cut diamond was left with its own personality. The proportions were designed to make the most of the available light at the time which was, of course, candlelight. The warmth of the candles was enhanced much more than it is in modern stones, in the same way that old mine cuts don’t usually have the “sparkle” of, say, a modern round brilliant diamond.

It might seem odd to describe any diamond as eco-friendly, but old mine cuts are just that. They are recycled and re-used with no subsequent demands on the environment. In fact, it could even be argued that there are enough diamonds already available in the world to keep us going indefinitely.

Fashions come and go, that’s no surprise. At the moment, the demand for vintage and antique styles is enormous, and nothing says antique better than an old mine cut diamond beautifully set into an engagement ring.

We can all but guarantee you’ll never get two old-mine cut diamonds that are the same. The very nature of how they are produced makes that impossible. Individuality, uniqueness, call it what you like, the result is the same. Well very different, actually, but you get the point.

Today, jewelry is made as much for a quick turnover and maximized profits as anything else. Back in the days of the old mine cuts, the aesthetic appeal was everything. Nobody was grading diamonds with the precision of today, so looks and light properties were just about everything. This meant beautiful stones with amazing effects on the available light.

In the last 60 or 70 years, civil war and internal conflicts of all types have been an everyday occurrence, and this means that diamonds have frequently been used to finance one or both sides in the fight. These blood diamonds are usually mined by workers in appalling conditions and smuggled to unscrupulous dealers to be sold for profits used to buy guns and bullets. Old mine cut diamonds precede such terrible times, and so are amongst the most ethically sourced diamonds in existence.

Final Thought

If you’re still not convinced about old mine cut diamonds, go and see a jeweler who has some in stock. Lay them down and compare them to modern, laser manufactured stones, and you’ll see the difference. The old mine cut may be a little more “rugged” than the modern stone, but it will be all the more beautiful for it.
