A diamond’s beauty is all about how it handles light. The most stunning diamonds reflect, refract and disperse light in a glorious display of fire, brilliance and scintillation. But it’s no accident they do this.
The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of …
Diamonds get their brilliance from three things: reflection, refraction and dispersion. Reflection is the light that hits the diamond and is …
Why does light disperse in a diamond?
When light enters a transparent substance such as water, glass, or diamond, it slows down significantly. This slowing causes light to ’bend’ or refract. Upon exiting the material back into air it speeds up again. Different wavelengths are bent at different rates and become separated or ’dispersed’.
What’s dispersion in a diamond?
an attractive optical effect of diamond known as fire or dispersion by diamond. The dispersion in diamond the red ray (B line of Fraunhofer’s spectrum at 687 nm) has refractive index of 2.407. The blue ray (G line of Fraunhofer’s spectrum at 430.8 nm) has an index of 2.451.
Do diamonds reflect or refract light?
Only a portion of the light hitting a diamond is reflected; the rest travels through it. As the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction.
What color light does a diamond reflect?
ilovebutter/Flickr The way that diamonds reflect light is unique: Inside the stone, the diamond will sparkle gray and white (known as “brilliance”) while outside of the gem, it will reflect rainbow colors onto other surfaces (this dispersed light is known as “fire”).
How can you tell if you have a real diamond?
Lay the stone onto the dot with the flat side down. Through the pointed end of the diamond, look down onto the paper. If you see a circular reflection inside the gemstone, the stone is fake. If you cannot see the dot or a reflection in the stone, then the diamond is real.
How do you tell if a diamond is real with a flashlight?
Simply hold the loose diamond near a light source, like a lamp, and see the reflection of the light from the diamond. This test will be best if there is another gem that you’ll compare along with it, like cubic zirconia. You’ll see how different their effects are to light.
Why does my diamond look rainbow?
One factor that determines a diamond’s level of brilliance is the cut. Real diamonds sparkle rainbow colors when their light is deflected to other surfaces. In other words, colors shoot from the diamond when the direct light hits the stone. This flash of colors from a diamond is called “fire.”
What color do real diamonds shine?
A real diamond appears gray and white inside (brilliance) when held to the light and can reflect rainbow colors (fire) onto other surfaces. A fake diamond will display rainbow colors within the stone when held up to light.
More Answers On Does Diamond Disperse Light
Do Diamonds Absorb Light? – Diamond101
Diamonds don’t absorb light; they reflect it, instead. That can serve as an interesting topic for discussion. So, if you’re willing to learn more about what determines how strong the reflection of your diamond is, how this reflection is created – and many more interesting facts about diamonds and light – you’re in for a treat.
What is Diamond Fire (Dispersion) And Why It Matters
The facets of a diamond act as a prism to refract light and split it into a spectrum of rainbow colors. A direct, concentrated source of light (e.g. LED) will allow the diamond to disperse it into visual colored flashes of light instead of a large, diffuse source of light (e.g. fluorescent tube).

visible light – Why do diamonds shine? – Physics Stack Exchange
The refractive index of diamond is pretty high ( 2.417) and is also dispersive (coefficient is 0.044). Due to this fact, diamond is an important application in optics. Consider an ideal cut diamond. I explain according to the figure below. When the light is incident at an angle 1, it refracts inside and travels through the lattice.
The “Clear-Cut” Indicator: Measuring a Diamond’s Flawlessness
Diamonds appear drab if the light travels through a shallow cut because the light stays at the bottom and doesn’t bounce back to the top. On the other hand, diamonds with a deep cut tend to have a portion that is dark because the travelling light only leaks through their sides. Accurately cut diamonds disperse light equally.
Some Good Diamonds Look Dark in Sunlight
Jul 1, 2020Scintillation is how the light emerging from the diamond plays and flashes giving the diamond its sparkle as the diamond is moved. The sparkle can be bright white or coloured firey flashes. Fire of the stone is how the facets refract and disperse the light into the colours of the rainbow.
What Makes a Diamond Shine? – William Goldberg
In essence, diamonds are tiny, complicated prisms; the light enters through the top, and then is angled around the inside of the diamond before being aimed back towards the top and out through the surface. This creates a rainbow effect (dispersion), and adds to the shine.
Physics Tutorial: Dispersion of Light by Prisms
The Angle of Deviation. The amount of overall refraction caused by the passage of a light ray through a prism is often expressed in terms of the angle of deviation ().The angle of deviation is the angle made between the incident ray of light entering the first face of the prism and the refracted ray that emerges from the second face of the prism. Because of the different indices of refraction …
What is Diamond Fluorescence? – Diamonds Under Black Light
When a diamond is exposed to ultraviolet light (also known as blacklight), it glows blue. Sometimes you might see another color too like yellow, green, red & white, but blue is the most common fluorescent color in a diamond. Let’s make it simple to understanding diamond fluorescence.
Visible Absorption Spectra of Colored Diamonds
When white light strikes a polished diamond, some of the light is reflected, while the rest enters the diamond where it is refracted and dispersed based on wavelength. Some of the light energies (i.e., wavelengths) are absorbed by the defects, while the unabsorbed wavelengths are transmitted.
How Light Affects a Diamond’s Appearance – GIA 4Cs
This symphony of reflected light is made up of brilliance (the total light reflected from a diamond), fire (the dispersion of light into the colors of the spectrum), and scintillation (the pattern of light and dark areas and the flashes of light or sparkle when a diamond is moved).

Light Performance – Quality Diamond Engagement Rings
As the refracted light exits the diamond, it’s dispersed into a spectrum (c). Diamond experts refer to these rainbow colours caused by light dispersal as fire. It’s well documented that old cut diamonds with steep crown angles and small tables have more fire, but usually this is at the expense of brilliance.
my diamond seems to sparkle more in dim light… | PriceScope
Diamonds disperse light into their spectral colors (like a prism). If a ray of dispersed light reaches the pupil of your eye and that ray is wider than your pupil you see a flash of color if your pupil “clips” it before it recombines. But if your pupil is wider than the ray you perceive all the colors at once and see it as white light.
