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.

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.

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.

Old mine cut diamonds precede such terrible times, and so are amongst the most ethically sourced diamonds in existence. Benjamin Khordipour is one of the researchers and gemologists at Estate Diamond Jewelry.

Thank you and best wishes, Yoram. So how would someone go about getting something appraised? But in this bag was a butterfly pendent.

It has 2 green stones and like 13 clear stones. Because of how well it was made I figured it was just high end antique costume jewelry.

I have even found simular pictures of antique jewelry with the same cut. Always referred to as mine cut. Now the stones in my pendant in regular light are just clear.

I took it to a jewelry store the woman checked it for being fake. She looked at it told me she believed it was probably cut crystals.

There was no facets. Homes theater etc were dark lit with candles an oil lamps. That a woman would have that one piece of jewelry that was expensive that she would wear on special occasions anyway how do I find someone that can appraise it.

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.

In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud.
