One of the most popular gemstones throughout history is the diamond. Durable, optically pleasing, and possessing a unique heirloom quality, diamonds are highly prized. According to the 2021 Jewelry & Engagement Study by The Knot, 86% of engagement rings contain a diamond center stone. Convincing a consumer of the appeal of a diamond is not particularly difficult. The bigger challenge comes in educating them on what contributes to their diamond’s quality and overall value.
