Diamond Selection - 4C´s and an F

When purchasing a diamond, and considering the 4 C´s, there is one often overlooked aspect of diamonds that really should be addressed, fluorescence. Fluorescence is the phenomenon that makes some diamonds emit a blue glow when exposed to fluorescent lighting. If fluorescence is strong, the diamond appears to have a bluish halo around it. It may look fantastic under store lighting, but when taken outside it somehow looks foggy. It is often something not addressed by jewelry stores, as it greatly detracts both from the appearance and the value of a diamond. If the diamond has a grading report, it will say whether the fluorescence is none, faint, medium, or strong. You don´t want strong flourescence.
