Diamonds are the most popular gemstone all over the world.

Why Do We Mine Diamonds?

Diamonds are most definitely the favorite gemstone of all, especially among jewelry shoppers in the United States and throughout the world. The United States is the largest consumer of diamonds in the world accounting for almost 40% of Diamond purchases. So what is the process of diamond mining? Where exactly are they found in the ground? And how far do miners have to go to find them?

Well, as your top choice for Austin Diamond Buyers, we are here to share all the industry secrets with you. And if you remember our earlier post on how we Eliminate the Middleman, then you will remember that we also provide the best prices for your diamonds.

Now, back to the mines…

Diamond Mining in the United States

Even though the United States is the largest consumer of gem-quality diamonds, there is no commercial mine production in the US. The only mine in the US that produces gem-quality diamonds is The Crater of Diamonds State Park in Arkansas, where guests can pay a small fee to mine for diamonds inside the park. And best of all, the rule of “finders keepers” applies here.

How are Diamonds Mined?

The process of diamond creation begins 100 miles underground where tremendous heat and pressure crystallize carbon into rough diamonds. Since the 1870s, most of the world’s gem-quality diamonds have been mined in Africa. Today, Diamond mining is also common in Russia and Canada and continues to grow. Pit-mining is the most popular way to recover diamonds. Pit mining requires the use of heavy machinery, hydraulic shovels, and trucks to mine diamonds from the depths of kimberlite pipes.

Another common mining method is open-pit mining which is possible only when diamonds are found on the surface. Diamonds are also mined from the seabed using horizontal and vertical marine mining. Mining from the sea requires going to depths of up to 1,000 meters.

Diamonds have been on the Earth for more than a million years…

Rough Diamonds

After diamonds are mined they are put in categories and are measured, weighed, and sorted before cutting them. Diamonds are then sorted again by weight, color, and clarity. Rough diamonds are sorted into three categories gem quality, industrial quality, and boart. Once this whole diamond sorting process is complete, the diamond cutting process begins.

Diamonds are valued based on numerous factors known as the 4C’s of diamond grading. When you come to us to sell your diamonds we’ll explain to you the whole process and help you get the best price.

Diamond mining is a long process that started millions of years ago. At M.I. Trading LLC, we’ll buy your diamond no matter which diamond mining process it went through to get to you. We are your premier diamond buyer in Austin, Texas. Bring your diamond in for a no obligation appraisal today.

After researching, reading reviews & visiting a few "seemingly" good jewelers, I made up my mind and I chose to do business with M.I. Trading. I felt they were above the others in every way.
Other jewelers made me feel like they were doing me a favor even looking at the jewelry which I wanted to sell. Some others low balled me.
I knew I found someone that I could trust when I went to M.I Trading. Moran did not rush me. He explained everything to me and was completely transparent, because he wanted me to make educated decisions. Nobody else even came close to caring about my business, never mind taking the time to educate me.
At M.I. Trading, I had the opportunity to think about what I wanted to do, without any pressure ... and when I decided what I wanted to sell, Moran gave me TOP DOLLAR.
I could not be happier that I found M.I. Trading, a company that I can trust.

The wife and I had some flatware to sell. We did some research and came up with a bottom price we would accept and a "wishful thinking" price we would really like. After checking reviews, we settled on M.I.Trading and mad an appointment. Upon arrival we met with Moran and he talked us through the process, how it was weighed and answered all of our questions. When it was said and done, Moran came up with a number that was just short of our "wishing" number. We shook hands, he handed us a check and had us on our way faster than I thought. We would highly recommend M. I. Trading.

I recently decided to sell some sterling silver flatware and other items that were languishing in storage, not wanted by relatives.
I found M.I. Trading on line. Mr. Tairy responded to voicemail immediately and met me at his office the next day. He was helpful, professional, and forthright. He evaluated everything and made an immediate offer. I was sorry to see my pretty things go but left within the hour with a cheque for a substantial and fair price.

He was truly helpful during a time that I was overwhelmed by what was left for me by my mother. He was very straight forward about everything. Will be coming back for sure.

Moran is the best in the business. I shopped around before selling my gold and silver, and Moran not only offered me the most for my pieces, but was extremely thorough in his process, communicative, and funny! His near 20 year experience in the industry speaks for its self. He is extremely knowledgeable. There is no one else I will ever use. Moran has exclusively earned my business for the foreseeable future.

I went by for a quick appraisal and Moran was able to squeeze me in without an appointment, which I highly recommend.
I’m looking forward to doing business with them again.

The owner was very knowledgeable about not only gold but silver and miscellaneous jewelry as well. He carefully evaluated the many items I had collected from my mother's estate and then sorted them into groups depending upon their value. After spending approximately an hour evaluating the items I brought him he determined the value and wrote us a check in an amount that I felt was extremely fair.
