Diamonds are truly a marvel of nature. Carbon crystallizes into the element diamond at a depth of approximately 60 kilometers within the Earth. The purity of a diamond describes how perfectly this process occurred. You may have heard the term "flawless" before. Flawless means that the crystal is free from inclusions when viewed under 10x magnification. Inclusions can be natural carbon residues or small cracks. For colorless diamonds, the clearer the diamond, the rarer and more expensive it is per carat.

What is meant by the clarity of a diamond? Inclusions are referred to as impurities in diamonds. These can include carbon residues that did not crystallize during the diamond formation process, as well as small cracks or bubbles. A diamond is considered flawless when it exhibits no inclusions internally or externally under 10x magnification.
Does my diamond have to be flawless? That is for you to decide. Flawless diamonds are rarer than those with slight inclusions. However, it can be said that inclusions in diamonds up to the VS clarity grade are not visible to the naked eye. If the cut is perfect, diamonds with slight inclusions can still exhibit excellent sparkle. Ultimately, it depends on your personal preference.
