Gleaming in the sun, a rainbow of colors sparkle forth as we watch her hand move side to side displaying a priceless jewel. Diamonds have marked important occasions in our lives not because of their beauty but as a reminder of what it takes to have a precious jewel of a relationship in our lives. Everyone asks how he proposed, but do you know how that rock actually made it onto a hand? Keep reading to find out.

Diamond Formation

High pressure combines with high heat in the earth’s mantle in vertical pipes of igneous rock. Volcanic action then thrusts those rocks closer to the surface. As these rocks cool, portions crystallize and form the diamonds. The rock called kimberlite acts as a marker during excavation for the diamonds.

Diamond Mining

A few diamonds can be found in rivers, streams and on the surface of the earth. In Crater of Diamonds State Park in Arkansas, visitors can hunt for surface diamonds. Most deposits are located by finding kimberlite rock deposits made by volcanoes. While there are those limited places where diamonds are near the surface, most diamonds are found using pit mining. The pit mining process begins with drilling and blasting a site. Large hydraulic shovels remove the debris for sifting, leaving a large hole in the earth’s surface. The digging continues until the kimberlite pipe is mined from the igneous rock.

Coastal Mining

Coastal mining is a form of open pit mining along a coast. It begins like open pit mining with the digging and use of hydraulic equipment. Seawalls must be built to help the process. Land becomes modified until the process is done. Water has to be pumped out in order to .

Seabed Mining

Diamond deposits do exist in the ocean. To harvest these using marine mining, it involves the use of remotely operated vehicles. A continuous line bucket system removes material as does as a marine hydraulic suction system. Mud becomes transferred to a ship for holding while the search for diamonds happens.
We love the fact that diamonds are not easily obtained but must be earned. Diamonds make grand gifts, but the formation of such a gem reflects what life does with each couple — refinement till it sparkles even in the darkest night. The best diamonds are found at Snow’s Jewelers.
