THE 4CS OF DIAMONDS
Lab-grown diamonds are grown within sophisticated laboratories with controlled environmental parameters that replicate the growth process of a natural diamond inside the Earth’s crust. The only difference is the time it takes for the diamond to grow. Lab-grown diamonds are also known as engineered, cultured, or lab-created diamonds. All our lab-grown diamonds are of flawless Type IIA quality and are grown from seeds of the finest Type IIA diamonds. Pure carbon layers are deposited by advanced technological processes, resulting in 100% carbon diamonds with no trace elements of nitrogen or boron.
A diamond’s symmetry, proportion, and polish make up what is known as the cut of the diamond, with the quality of the cut directly corresponding to a diamond’s brilliance. Our Diamond Foundry cuts are graded on a scale from Signature Ideal—the highest grade (that’s “Excellent” by GIA standards)—to Poor—the lowest grade. Whereas a good cut leads to maximum light return (a.k.a. what makes your stone reflect and shine), in a poorly cut diamond, light tends to go out through the bottom of the stone, leading to a duller appearance. While not one of the 4C’s, the diamond shape will impact the cut’s brilliance, so we recommend keeping the shape in mind when considering the cut.
Graded on the absence of color, a diamond’s value is based on a scale ranging from D (perfectly transparent) to Z (pale yellow). To a naked or untrained eye, colorless to near colorless diamonds will appear clear, or D-J on the color scale. The D-F stones, however, are extremely rare, with nearly all diamonds on the market ranging from G-I. As such, our selection features only colorless and near-colorless diamonds that are I and above.
The most well-known “C” is slightly misunderstood—carat refers to a diamond’s weight, not size. The term comes from the word “carob”, the type of seeds historically used by diamond traders to measure diamond weight. For reference, one carat is about 0.2 grams or the weight of a paper clip.
Clarity is determined by the number of inclusions or unique imperfections in the stone. Clarity is harder to notice without the help of a magnifier. Flawless diamonds without any inclusions are extremely rare. We suggest selecting diamonds graded SI1 or above with a higher clarity grade to maximize the brilliance of the stone; internal spots and lines can affect how light passes through the stone.
