FAQs
The fire of a diamond doesn't mean it is literally on fire, but rather is a reference to the colourful flashes of light that the stone diffuses whilst under the light. It's otherwise known as 'light dispersion' as this is an accurate description of how the colourful flashes are formed.
What causes the fire in diamond? ›
Diamond fire is primarily caused by the refraction of light as it passes through the diamond. When white light enters the diamond, it is separated into its constituent wavelengths, creating a rainbow effect.
What is the diamond fire? ›
Different wavelengths are bent at different rates and become separated or 'dispersed'. It is this dispersion that allows for an observer to see the individual colors of a rainbow, colors refracted by a prism, and 'fire' from a diamond.
What is the difference between brilliance and fire in diamonds? ›
Fire vs Brilliance
Brilliance is how bright and white a diamond is. A diamond with great brilliance will exhibit great light return. Fire, on the other hand, is simply the colorful light a diamond gives off. A diamond's cut directly impacts how much brilliance and fire a diamond will have.
What is the purpose of the fire diamond? ›
The system addresses the health, flammability, instability, and special hazards presented from short-term, acute exposures that could occur as a result of a fire, spill, or similar emergency.
What is the point of fire diamond? ›
Fire Marshal J. F. Morris developed the diamond shaped placard as a marking system to indicate when a building contained hazardous materials, with their levels of flammability, reactivity and health effects.
How to see fire in a diamond? ›
Fire is the flashes of colored light seen on the diamond's crown when a stone is moved back and forth and catches the light. If you want to get all scientific, fire is the dispersion of light. When a diamond is well cut, light can appear as a rainbow of color.
Do you want fire in a diamond? ›
Most diamonds should display fire qualities but the amount of fire won't be the same for every diamond. So if you want a fiery ring that truly dazzles and delights, look for high cut quality and clarity. With these qualities considered, you can find a diamond with high fire and sparkle.
What is the meaning of fire in gemstones? ›
Fire in a gem stone refers to the sparkle that is influenced by the color of a gem when exposed to light. It is most often used to describe the light refracted by a diamond. It is the counterpart of brilliance, or the colorless light emitted by a gemstone.
Does moissanite sparkle more than diamonds? ›
Moissanite is actually more brilliant than a diamond!
Brilliance, which refers to a stone's ability to reflect white light, is a good measure for how much a gemstone will 'sparkle'. Moissanite's brilliance is higher than diamond's due to its higher “refractive index” (Diamond's is 2.42, whereas Moissanite's is 2.65).
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 colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.
What is the difference between moissanite and fire diamond? ›
Moissanite also shows both, but typically has more fire than diamond. So, moissanite tends to have more colored flashes of light than diamond. However, this depends partly on the diamond cut. Diamonds with older cut styles or modern cuts with certain angles will show more fire than most modern diamonds.
Is the fire of a diamond good or bad? ›
The brighter and more colored flashes of light seen in the diamond, the better the grade it receives. In general, the smaller the table facet of a diamond, the more fire the diamond can produce. Fire tends to decrease as table % increases due to a lesser area for crown facets to produce fire.
Are fire light diamonds real? ›
Lab Diamonds are Real
They have the same chemical, physical, and optical properties as mined diamonds and exhibit the same fire, scintillation, and sparkle.
What does fire mean in jewelry? ›
Fire in a gem stone refers to the sparkle that is influenced by the color of a gem when exposed to light. It is most often used to describe the light refracted by a diamond. It is the counterpart of brilliance, or the colorless light emitted by a gemstone.
What does fire mean in gemstones? ›
In the context of gemstones, the word 'fire' is used to describe the breaking up of white light into its constituent colors, an effect that can be demonstrated well by shining light into a prism and witnessing the resultant rainbow of colors that exit on the other side.
