Fluorescence, in gemology, refers to the phenomenon that gems and minerals emit light when excited by external energy (such as ultraviolet rays, X-rays, etc.), and the luminescence stops immediately after the excitation source is removed; "lighting" is a popular commercial term in the jade market. Described as a kind of soft, sinuous white light produced when shaking the jade, like the moonlight under the thin clouds at night, elegant and ethereal. So, what kind of jadeite has this wonderful phenomenon?
colour
In general, the white, colorless jade "lighting" phenomenon is obvious, although green and other dark jade can also have "lighting" phenomenon, but the rich color will weaken its effect.
Processing
When the light is injected into the polished curved jade jewelry (bangle, ring face and partial curved surface carvings, etc.), it can be refracted and reflected so that the light is inside the jade or condensed or diverged, resulting in Fluorescence phenomenon. Therefore, the curved shape and the degree of polishing are also necessary conditions for the jade to "fire".
Emerald texture
The texture of jadeite is an important factor in the phenomenon of “fluorescenceâ€. The finer the mineral particles that make up jadeite, the finer the texture, the higher the transparency, the more likely the “fluorescence†phenomenon occurs. Generally speaking, the glass species and the ice type jade This phenomenon can occur. Therefore, the “Flying†jadeite is generally a fine quality product and is expensive.
It is worth noting that "the extremes of the object must be reversed". If the transparency of the jadeite is extremely high and clear, such as water, the incident light directly penetrates the jade, then the phenomenon of "lighting" cannot occur.
