2023年7月18日 · Diamond fluorescence is a fascinating phenomenon where diamonds glow when exposed to long-wave UV rays. It can sometimes increase or decrease the value of a diamond. It can also affect diamond appearance—or not.

2012年5月9日 · Diamond fluorescence, in its most simple form, is the effect that ultraviolet (UV) light has on a diamond. When you stand under a blue light or ultraviolet light, sometimes you can see your whites get brighter or your teeth appear to glow.

2023年12月11日 · Diamond fluorescence refers to the glow a diamond emits under ultra-violet (UV) light, often seen as a blue hue. The GIA has five fluorescence grades: None, Faint, Medium, Strong, and Very Strong. While 30% of diamonds exhibit this glow, its impact varies: it can enhance a diamond’s color or cause a hazy appearance.

2024年12月7日 · Fluorescence is an invisible glow that some diamonds emit under Ultraviolet (UV) rays. In some cases, fluorescence is neither good nor bad, serving merely as an identifying characteristic. In other cases, however, it might negatively affect the stone's brilliance.

Diamond fluorescence refers to the phenomenon where a diamond emits a visible glow when exposed to ultraviolet (UV) light. It is caused by certain minerals or impurities present in the diamond's structure. Fluorescence can range from none (no fluorescence) to …

Fluorescence refers to the discharge of light by a diamond after it is subjected to electromagnetic radiation (e.g. ultraviolet light). Some common sources of UV radiation include black lighting from night clubs, fluorescent bulbs and natural sunlight.

When a diamond is subjected to ultraviolet light – be it from the sun, fluorescent bulbs, strobe lights or any other UV sources – the diamond may respond by emitting this subtle colored glow, what we know as fluorescence. What Causes Fluorescence in Diamonds?

2023年7月31日 · Fluorescence is simply the diamond's reaction to UV light, a.k.a. black light. Diamonds with fluorescence will glow or radiate a blue color in a UV environment. (This glow can also be white, yellow, green or even red). Fluorescence can be found in about 30% of all gem-quality diamonds.

Diamond Fluorescence. Fluorescence is the tendency of a diamond to emit a (soft) glow when exposed to ultraviolet light (UV light). The fluorescence effect is present in over 30% of diamonds and is an important consideration when buying a loose diamond.

Fluorescence is a natural occurrence that can give some diamonds a special glow. The energy of visible light – in the form of photons – excites atoms of the diamond, and they reemit that light almost immediately – within about 10 −8 seconds.
