What is si diamond?

SI diamond is a term used to describe a diamond with a clarity grade of "Slightly Included". This means that the diamond has some internal or external blemishes or inclusions that are visible under 10x magnification. These inclusions can affect the diamond's light performance and overall visual appearance.

SI diamond is a popular choice for engagement rings and other fine jewelry pieces as they offer an excellent balance of quality, beauty, and affordability. SI diamonds are not as expensive as their higher clarity counterparts, but still have good eye appeal and sparkle.

When buying an SI diamond, it is important to review the diamond certificate from an independent gemological laboratory like GIA or AGS. This will provide a detailed assessment of the diamond's quality, including its clarity grade, color grade, cut quality, and carat weight. The diamond's unique features, such as its inclusions, can also be seen in the certificate.

Overall, SI diamond is a great option for those looking for a high-quality diamond at an affordable price point.
