We put a lot of value on diamonds, and for good reason. These geologic gems are tough, rare, and able to withstand the test of time. It’s no wonder that we’ve associated diamond jewelry with important life events such as engagements, weddings and anniversaries.
At Dallas Gold & Silver Exchange, we see lots of people come in looking for the perfect stone to celebrate the best moments of their lives, but what about the life events of a diamond? This led us to answer the question—How are diamonds formed?
Birth of a Diamond
Diamonds are formed in the upper mantle of the Earth, about 100 miles below the Earth’s surface. It is an environment of extreme heat and pressure, perfect for compressing carbon molecules and making diamonds.
Molecularly, diamonds are carbon atoms tightly fit together through covalent bonds. Each carbon atom is linked to four other carbon atoms, creating a crystalline structure that is both strong and beautiful. These carbon atoms are further fused together because of the extreme heat and pressure that exists in the upper mantle. Temperatures of upwards of 2,700°F help create diamonds.
The creation of diamonds occurs well below the Earth’s surface in an area that is unreachable by human means. Therefore, diamonds must be pushed up towards the Earth’s surface. This is actually accomplished through the process of certain volcanic eruptions that occurred a long time ago.
These quick violent eruptions cooled and left Kimberlite formations (or “pipes”) within the Earth’s surface. Kimberlite is a natural sediment that contains the most abundant source of mined diamonds today.
At Dallas Gold & Silver Exchange, we’re happy to sell beautiful diamond jewelry in the form of wedding and engagement rings, anniversary and eternity bands, estate jewelry and more to represent the most special moments in your life.
