Gemstone Fluorescence Chart

Gemstone Fluorescence Chart - Web gemstone hardness & fluorescence: Fluorescence is a phenomenon that causes a mineral to glow in the within the visible spectrum when exposed to ultraviolet light. Importantly, not all specimens of these minerals will fluoresce, as minerals typically require an ion actuator to glow. Diagram that shows how photons and electrons interact to produce the fluorescence phenomenon. No graphs, colors, reference charts, or data to interpret to determine if your stone is a natural diamond or not. Fluorescence is the emission of visible light by a gemstone when exposed to electromagnetic radiation of a higher energy (shorter wavelength). These gems are also renowned for their fluorescence. For example, yellow topaz shows orange fluorescence, opal shows blue fluorescence, and ruby shows red fluorescence. Web for most gem buyers, color is probably the most well known of the four cs of gem grading. In just two seconds you get a simple pass for natural diamonds and refer for stones that need more testing.
