Fluorescence in diamonds is caused by exposure to ultraviolet (UV) light which excites the atoms within the diamond, causing them to emit visible light. Certain impurities or defects within the diamond crystal lattice can also contribute to fluorescence, resulting in different colors such as blue, yellow, or white fluorescence.

Fluorescence is not produced by electric current directly. Fluorescence occurs when a substance absorbs light at one wavelength and re-emits it at a longer wavelength. This process can be induced by various methods such as exposure to light or other forms of electromagnetic radiation.

Some organisms that exhibit fluorescence under ultraviolet light include corals, some types of fish, scorpions, and certain types of flowers. This phenomenon occurs due to the presence of certain fluorescent proteins or pigments in their tissues.

The ability of a mineral or substance to glow during and after exposure to ultraviolet light is called fluorescence. If it continues to glow after the ultraviolet light has been turned off the effect is called phosphorescence.

Inflorescence is a botanical term that describes a cluster of flowers on a plant, which is contrasted with single flowers that do not occur in bunches. You can kind of see the root "flor" give away the reference to flowers.
Florescence is a word that describes a period of flourishing, but it is merely one letter away from a far more commonly used word, "fluorescence".
Fluorescence is defined as the emission of electromagnetic radiation by a substance that is stimulated by incident radiation. That's a very broad definition, but the term is often used to apply to minerals that glow any color in the visible spectrum when exposed to invisible ultraviolet radiation.
Fluorescence is distinct from incandescence and luminescence. Influorescence generally describes the emission of visible light, it can also apply to the emission of wavelengths that are invisible; however it also stipulates such emissions are spurred by the absorption of electromagnetic radiation. Incandescence and luminescence both are defined as emitting visible light only, with the former being induced by the application of heat, and the latter being induced by non-thermal means (such as chemical reactions).
With all of this said, it's worth pointing out that "influorescence" is not a word.

Fluorescence polarization is a technique that measures the rotational motion of fluorescent molecules in a sample using polarized light. Anisotropy is a measure of the degree of polarization of fluorescence emitted by a sample, which can provide information about the size, shape, and rotational mobility of molecules.

A real diamond will not glow under a black light. You can shine the black light over the diamond to check for phosphorescence or fluorescence, which can indicate if it's a real or synthetic diamond. However, it's recommended to have a professional jeweler verify the authenticity of the diamond using specialized tools.

No, fluorescent materials typically do not glow under infrared light. Fluorescent materials absorb ultraviolet or visible light and then re-emit light at a longer wavelength, usually in the visible range. Infrared light is outside this range and does not stimulate fluorescence in these materials.

Some special properties of minerals that apply to only a few include fluorescence (ability to emit light when exposed to ultraviolet light), pleochroism (displaying different colors when viewed from different angles), and iridescence (displaying rainbow-like colors). These unique properties can help in identifying specific minerals.

The word Neon is synonymous with brilliantly colored signs and lighting. The Packard company displayed one of the first neon signs meant for commercial advertising in the early 1900's and, not long after, merchants began to realize neon's potential for grabbing attention.
By the 1920's neon displayed at the fist world fare helped to showcase the latest in technology there. Since then we've used neon to create ambiance and excitement for businesses and brands all over the world.
Neon lights come in many vibrant colors and fabrication styles. Minerals that exhibit florescence when illuminated are used to coat the inside of glass tubing. Color pigment may also be embedded in the glass itself. "Fill" gases such as Argon, Neon, and Helium are used inside of a vacuumed tube with electrodes placed on each end for the introduction of electricity to achieve color and illumination.
Neon Gas produces a brilliant red glow when illuminated. Argon and helium are combined to produce a dim blue light. Argon and helium serve as a carrier for minuscule amounts of Mercury added to evoke the brilliant glow found in fluorescent lighting. These factors are combined to achieve brilliance in neon color and design.

The photoelectric effect is the process where photons (light) of sufficient energy knock electrons out of a material, creating an electric current. Fluorescence is when a material absorbs light energy and then re-emits it at a longer wavelength, typically after a short delay. While the photoelectric effect involves the ejection of electrons, fluorescence does not result in the ejection of electrons from the material.

Uranium can glow due to its natural radioactivity, which emits energy in the form of particles and waves. This energy can cause certain materials, like phosphors, to fluoresce or emit light when they absorb it. This phenomenon is used in various applications such as fluorescent lamps and glow-in-the-dark products.

The brightness of a light bulb is determined by the amount of electrical power (wattage) it consumes. Higher wattage bulbs generally produce more light, resulting in a brighter output. The type of bulb, such as incandescent, LED, or fluorescent, also affects the brightness as each technology has different efficiencies.

Rarity
Of the 4 C's, Carat Weight is probably one of the most important considerations with respect to rarity, value, and consumer preference. In fact, Carat Weight, or how much the diamond weighs is the most significant value factor in a diamond. Because diamonds by nature are rare, a 2 carat diamond is actually about 3 times more valuable than a comparable quality 1 carat size. Statistically a 1 carat is one in a million diamonds mined, and a 2 carat is one in five million diamonds mined. Therefore, all things considered a 2 carat diamond is really "value priced" based on the rarity factor.
Pricing
Larger diamonds are much more rare, thus commanding a higher price/per/carat. Carat weight affects the value of a diamond by about 10-20% for each step in size difference. Also, "magic sizes" refer to major carat weight categories, for example exactly 1.00 carat, or larger, and can prompt "price premiums". To calculate the price of a diamond you multiply the carat weight by the price/per/carat. For example: if a 1.25 carat diamond was priced at $10,000 per/carat the diamond would be sold for $12,500.

Bella Swan sees Edward Cullen for the first time in Science 'Biology'. At this point he's staring at her, with his hands on his mouth, like he's in pain the whole time and so she gets parodied (she thinks its because her hair smells). Also at the same time his eyes are Black.
Then Edward and his family (The other Cullens;Alice,Jasper,Rosalie and Emmett). Don't come into school for 3 days. She starts noticing because she normally sits next to him in science 'Biology' . Then when he does decide to come in. He finaly introduces himself, and they together win a prize (The Golden Onion). And then she realises that his eyes are different (When walking together to the locker after Science 'Biology' with The Golden Onion). Because the last time she saw him they were black. But they were Golden Brown so she says ''Hey did you get contacts your eyes were... black''. And Edward Cullen says ''No Its the florescence's' and then he walks off.
Later on she starts to get interested in him. And so, when she goes to 'la Push' with Jakob Black. They start talking about legends . And some rumours come out about the Cullen's . Then she googles Vampire's and goes on a site called 'Apotamki' legends etc. She also uses the guidelines of the net,books.
She is also able to think - about Edward's cold and pale skin; Like when they were both in his car and they both reach for the heater button and there hands touch and she jurks, cringes away because his hands are so cold . And his unimaginable speed(with which he got over to her to save her from the car that was about to hit her) and also the powerful strength (with which he stopped the car that was about to hit her) And he smells nice and is perfectly beautiful which of course this is all to invite you in. And that's how Bella Swan knows that Edward Cullen's a vampire.
