Diamonds - From the Ground to Your Finger

For centuries diamonds have fascinated mankind.  It is estimated that it takes about 3 million years to create a diamond and it might be the oldest item you own.  As we explore the process of how diamonds are formed to how they make it to market, Motek Diamonds is here to answer all of your diamond wedding ring, engagement ring, and wholesale loose diamond questions in Dallas, Texas.

How a diamond is formed

For centuries diamond clusters have been found close to the earth's surface and dug out of the surface by early civilizations.  Until 50 years ago, we now know that diamonds are formed 60 miles beneath the surface of the earth.  Massive amounts of pressure and the incredible heat this far underground compresses pure carbon into hard geological stones.  3 million years of pressures changes the structure into rough diamonds that are forced upwards to the surface through "Kimberlite Pipes" which are a natural geological process in which gas and magma push toward the surface of the earth and can erupt like a volcano.  These "pipes" push earths inner layers toward to earth and eventually the molten magma cools leaving the rough diamonds in round columns near the earth's crust.  Then the mining process can begin.

There are 3 stages a diamond must go through before it makes it to your jeweler.

1. Mining

Since the diamonds are in round columns of earth, most mines are circular and excavation begins from the top of the earth and slowly begins to dig down in concentric circles allowing for miners to go up and down as they please.

Industrial excavators dig up the earth and is transported away from the dig site to a place where machines sift through the earth in search of the precious stones.  If the earth is too hard, explosives are used to break up the earth enough to get the stones out.

Diamonds found in this state are called rough diamonds and are sent to diamond cutters to shape and cut the diamond into a beautiful work of art.  Some diamonds are not valuable as jewels and are sold for industrial cutting because diamonds are very very hard. You will find in your local home improvement store diamond drill bits which have diamond dust attached to the bit to make it last longer and cut through tough concrete and rocks.

2. Cutting

Rough diamonds are sent to diamond cutters in which diamonds are removed from the earth and are sorted into 5000 types.  They are examined to determine how to cut each one to get the highest value.  Skilled diamond cutters cut each diamond up to 60 times creating loose diamonds.  Loose diamonds are polished and are sold to wholesalers.

3. Wholesalers 

Diamond wholesales buy diamonds in volumes and distributes them to jewelry stores which purchase them or keep them as consignment.  In fact, Motek Diamonds was one of Dallas' first diamond wholesalers almost 40 years ago.

4. Retail

Jewelry stores are sold at retail value and vary in price based on it's rarity.  Colorless diamonds are the most valuable while yellow diamonds aren't as common and are more affordable.  Most engagement rings and wedding rings have some level of yellow color but not visible to the naked eye.  Motek Diamonds has been providing excellent service and dedication to the Dallas market for wedding rings, loose diamonds, and engagement rings.
