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.

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.
If you are interested in learning more about gemstones and gemology, you need to check out this epic list of FREE courses and resources we had curated.
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. 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.
Coastal ships fitted with vacuum suction tubes for marine mining. Deposits of diamonds found in marine bodies are a result of kimberlite pipe erosion.
When heavy rain occurs, the exposed diamonds are washed into rivers and carried towards the coast. Namibia is a country that holds the biggest quantity of gem quality marine deposits in the world.
Currently, the country has a partnership with De Beers to conduct marine-based recovery and it has produced more volume than land based mining.
Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them.
Some of these methods include shallow-water mining, deep sea operations involving high tech equipment and simple alluvial mining.
Like open pit mining, the ore materials are usually transported offsite for further processing. Did you know that alluvial mining can cause serious deterioration and damage to our natural environment?
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.
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. 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.
