Everyone has their own unique criteria for what features they want in an engagement ring with a diamond. Some want the biggest carat weight they can afford to have, others want a particular clarity level or cut, and some others want a flashy ring setting.
If you would like one with the maximum sparkle, you should familiarize with some terms. You have perhaps heard of diamond brilliance, but it also has the fire. Keep reading to know what fire is, how it differs from other properties and what to look for in a diamond to get the most fire.
What is Fire
The term ‘diamond fire’ alludes to the rainbow-colored flashes it generates. As you turn this stone, you will see flashes of yellow, orange, purple, blue and green light which almost look like bursts of fire. This is the byproduct of light dispersion. As the white light hits a transparent item like a diamond and passes through, its rays slow down. Simply put, this causes the light to be divided into many different colors. This effect is the same as a rainbow.
A diamond is very refractive, which means it disperses the light extremely well. This boosts the effect, causing the stone to show fire.
Fire versus Brilliance and Scintillation
You may come across all these terms used to refer to a diamond. These terms sound similar but are different from one another.
- Brilliance refers to the white light that you see. It happens when the sunlight enters the diamond’s top, bounces off its bottom half facets and exits through the top.
- Fire describes the colors you see because of the dispersion of light. It happens when the light enters it at an angle, then slows down and disperses into various colors.
- Scintillation is the light flashes that bounce off of the surface of this stone when you move it. It is also known as sparkle.
Why is Diamond Cut Important for the Brilliance and Fire?
The cut is the feature that determines how brilliant and sparkly the diamond is and how much fire it has. It describes how the angles and proportions of a diamond reflect the light too, not just the form. The light enters through the top of a well-cut diamond, bounces around and exits again through the top. However, it enters and leaks out the side or bottom of a poor cut diamond, so it will appear dull. Needless to say, what it will be like in a raw diamond.
If you are after the shiniest diamond, you must go for the best cut you can afford to buy. An excellent diamond cut will show exceptional brilliance and fire. Keep these in mind when you look to buy cut diamonds.
Best Sources of Light to See Fire
The light source plays a big role in the amount of fire you see too. The level of fire might just be muted in an environment with the inappropriate source of light. This is why the stones always look more sparkly in jewelry shops, where the best light combination is used to bring out their brilliance and fire. After all, the gemstone has to appeal to the eye of the viewer at the store itself for the sale purpose.
In a room, LED lights show the fire in a better way compared to fluorescent light. The second type of light is better for brilliance.
You will see the better fire when the diamond is put under a direct source of light too, like halogen spotlights or sunlight. In outdoor spaces, the direct natural light shows off the fire properties of the stone. A cloudy day, producing diffuse light, subdues the fire.
In addition, when the jewelry store has colored lights, rather than white ones, you may see a greater effect of fire in the gemstone that is not possible to replicate outdoors. When looking at its fire, see the gemstone under white light at all times.
Other Factors Affecting Diamond Fire
We have already mentioned that the most important factor of the lot is the cut of the stone. Here are the other factors, which affect the fire.
- Color: Whiter diamonds show greater fire properties. Do you prefer yellow diamonds more? If you do, remember that these will not display an equal amount of fire to white diamonds.
- Clarity: Plenty of big inclusions can block the light rays as these move through the gemstone, reducing the effect. Generally, we would suggest a clarity grade of SI1 or above.
- Dirt: When the diamond’s surface is dirty, it blocks the light that is exiting it, reducing the fire you see. So,it is best to keep the surface clean to keep your diamond sparkling.
