Buying a diamond is certainly an investment, so why don’t we approach it with the same method we would if we were buying a car or a house? For example, when purchasing a car, we want to know its history, when it was made, how it was made and its quality. We should extend that same line of thinking to buying a diamond, which is why we are bringing you a quick guide on what it is you’re buying.

What exactly is the chemistry of a diamond and how does it affect your purchase?

The Chemistry of a Diamond

Although diamond is a form of carbon, it is the hardest natural material known to man. Ironically, as diamonds are being made under the temperatures and pressures of earth, they are unstable and slowly change into graphite. But let’s look at its anatomy with a quick scientific explanation of its atomic structure as explained by The Chemistry of Carbon from Purdue University:

“The properties of diamond are a logical consequence of its structure. Carbon, with four valence electrons, forms covalent bonds to four neighboring carbon atoms arranged toward the corners of a tetrahedron. Each of these atoms is then bound to four other carbon atoms, which form bonds to four other carbon atoms, and so on. As a result, a perfect diamond can be thought of as a single giant molecule. The strength of the individual C-C bonds and their arrangement in space give rise to the unusual properties of diamond.”

Buying a Diamond

Now that you know the chemical foundation of what you’re buying, it’s time to put that knowledge to the test when buying your diamond. Whether you’re buying a loose diamond or a diamond engagement ring, these three “things to look for” apply across the board.

  • Keep the 4 C’s in Mind

Color, cut, clarity and carats (or the size of the diamond) all work together to make up the price of the diamond. The higher each of the C’s grades, the more expensive the diamond because it is a better quality. For more information, read Your Guide to Buying Diamonds.

  • The Certification

CNN reported that a diamond of a carat or more should come with a gem report — a gemologist’s evaluation of the stone’s color by letter grade (good stones are ranked no lower than I) and clarity, ranging from “flawless” (FL) to “very slight inclusions” (either VS1 or VS2).

  • The Setting

If your budget is quite tight, look at settings which can make the size of the center diamond appear larger. A halo setting for example, can make the ring as a whole appear larger.
