Approximately 30% of diamonds contain a certain level of boron, which causes precious gems to glow when exposed to ultraviolet rays, also known as black light. The level of boron present in the diamond determines the amount of light the diamond will emit when it is exposed. Diamonds glow with black light due to a phenomenon called fluorescence, and approximately 35% of natural diamonds show some degree of this effect. In nature, the presence of certain chemical impurities within the diamond composition triggers this brilliant effect in the presence of an ultraviolet light source.
Natural diamonds have a property known as fluorescence. This phenomenon allows diamonds to produce brilliance of varying colors when exposed to black light (also known as ultraviolet light). A pure, natural diamond is known to produce a blue glow when exposed to black light. Impure ones have certain chemical impurities that trigger the brilliance of other colors such as green, white, red and yellow when diamonds are exposed to ultraviolet light.
Diamond fluorescence refers to the effect of UV light on a diamond. When a diamond is exposed to ultraviolet light (also known as black light), it glows blue. Sometimes you may see another color, such as yellow, green, red, 26%, white, but blue is the most common fluorescent color in a diamond. It is due to a phenomenon called fluorescence present in diamonds that causes diamonds to glow in different shades of blue, purple, green and sometimes even red and yellow under ultraviolet light.
Fluorescence occurs when a diamond shows a soft glow under ultraviolet (UV) light. This is caused by certain minerals in the diamond. This effect is completely natural and appears in one third of all diamonds. The fact is that the brilliance and brilliance of the diamond is determined by the quality of its cut and not by its ability to shine with ultraviolet light.
However, not all diamonds fluoresce, some are fluorescence-free and are called “None” in the GIA diamond report. Blue fluorescence can help a diamond look whiter by counteracting the yellowish tint that a diamond has and can improve face up vision to half or a higher degree. Depending on the specific recipe and the alloys used in the cultivation process, laboratory diamonds may show rarer fluorescence colors, such as yellow-orange or white, compared to natural diamonds. Use a variety of methods, such as using a Presidium diamond tester, as well as magnifying the stone to look for characteristics other than diamond formation.
This is because when photons from UV sources hit the diamond, the impurities found in the diamond will cause it to emit the shine and it is not present in CZ, which is a common counterfeit that scammers use to imitate the diamond. Only 30-35% of diamonds fluoresce, the brightness of which depends on the strength or intensity of the reaction between diamond fluorescence and black light. If your diamond does not match, I suspect that you are seeing reflections instead of the emission of ultraviolet light from your diamond when mounted. You may have seen “Strong Blue” or “Medium Blue” on a diamond certificate, which means that diamonds emit “blue” light (fluorescence) when obtained from UV light.
In the above 2 examples, both diamonds are well-cut diamonds with similar carat weight, D color, and VVS1 clarity grades. Some diamonds glow in different colors, such as a bluish-purple color under black light, due to a phenomenon called fluorescence. When natural diamonds with the property of fluorescence are exposed to black light or ultraviolet light, they can shine in many different colors. I recently sold a diamond with medium fluorescence to a customer just because she wants her ring to shine at the party.
