Radiant diamonds are sometimes mixed up with emerald diamonds because they both have an elongated and elegant shape. The difference between these two types of diamonds lies in the sparkle factor; radiant diamonds sparkle significantly more than emerald ones.
Diamond clarity is the assessment of small imperfections on the surface and within the stone. Surface flaws are called blemishes, while internal defects are known as inclusions. In most cases, a diamond’s beauty is not affected by these since most inclusions can’t be seen with the naked eye. When referring to inclusions, gemologists often use the term “internal characteristics” instead of flaws.
