    All About Natural Diamonds

    Natural diamonds have been prized throughout the ages for their dazzling sparkle, rarity and emotional value. So whether you’re searching for an engagement ring or a gift of diamond jewelry for someone special, here’s what you need to know about nature’s oldest, most beautiful miracle: natural diamonds.

    3 quick things about natural diamonds

    What are Natural Diamonds?

    Natural diamonds are minerals composed almost entirely of carbon with trace amounts of nitrogen. They are also one of the hardest known natural substances on earth. Natural diamonds are mined from the ground and are then cut and polished to create the beautiful, sparkling gems that have been used in jewelry for centuries.

    How are Natural Diamonds Made?

    Natural diamonds were created billions of years ago, deep within the earth’s mantle. This high pressure, high temperature environment bonded carbon atoms together to form diamond crystals. Volcanic eruptions eventually pushed them upwards, where a finite amount of them now exist about 100 miles beneath the earth’s surface, just waiting to be unearthed and cherished by you and your loved one.

    Diamond Shapes

    Before making any decisions about natural diamonds for your engagement ring, you’ll need to pick a diamond shape. Here’s a quick primer on the different diamond engagement ring shapes you have to choose from.

    learn the 4cs

    What are the 4Cs of a Diamond? The 4Cs of a diamond are the universal standard that gemologists use to determine a diamond’s quality which includes the diamond’s cut, color, clarity, and carat weight What’s more, they show you what you should be looking for when purchasing a diamond. Here’s a brief overview of the 4Cs:


    The most important of the 4Cs of a diamond is cut. The cut of a diamond affects how well a diamond returns light back to your eye. It’s what makes the diamond sparkle! A diamond’s cut creates its brilliance, fire and scintillation, can hide small internal flaws (called inclusions), and can even make the diamond seem whiter.


    Diamond color actually measures the diamond’s lack of color. The less color in a diamond, the higher its value. Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). The highest quality diamonds are colorless—their grade will be D-F. Near colorless diamonds are graded G-H, and slight color is I-J. It’s important not to look at color on its own— make sure you take it into consideration with the other 3Cs. For example, a lower color with a better cut can result in a prettier diamond compared to a colorless diamond with a lesser cut.


    Diamond clarity is the measurement of minor imperfections on and inside a diamond. The surface flaws are called blemishes, and internal defects are known as inclusions. These natural imperfections are microscopic and do not impact a diamond’s beauty, but the fewer imperfections a diamond has, the better grade it will get.


    A diamond’s carat is not the visible size of a diamond. Rather, carat weight refers to the weight of the diamond as measured in carats. Diamonds with a larger carat weight are rarer, and the diamond’s value increases with it.
