It’s a burst of colors much like the “fireworks” that teen superhero Jubilee generates from her fingers (but without the temporary blindness or fatal detonation). 2: Diamond Fireįire is one of the most magical effects of a diamond. Imagine Emma Frost of X-Men fame in her all-white outfits, or better yet, in living-diamond form. It’s the awesome effect of all the internal and external white light reflected from a diamond’s facets back to your eyes. Some even say a diamond can’t be considered beautiful without it. 1: Diamond Brillianceīrilliance-also called brightness-is the first thing you notice about a diamond. They are known as go-to sellers of ideal cut diamonds. Look for super sparkle at sites like Whiteflash, Brian Gavin, and James Allen. They’re the BOOM! ZAP! WOW! effect that will have the woman of your dreams gobsmacked over the ring and utterly smitten with you.īigger isn’t always better. You’ll want to get to know these three really well. These are three other lesser-known attributes that contribute to a diamond’s beauty: brilliance, fire and scintillation. We’re not talking about the 4Cs here necessarily (although cut comes into play). Like most superheroes, diamonds have extraordinary powers. They’re basically indestructible and have been known to save the day (ask any guy who’s been in the doghouse). This article was contributed by Frank Fisher.Diamonds are the superheroes of the gemstone world. Fire is influenced by the angle of light that enters and exits the diamond and the interactions of the diamond facets with light, among others.įire is one of the main reasons why diamonds are desired and treasured by many people. The fire of diamonds differs, depending on the stone’s cut and polish, the lighting conditions and the viewing environments. The resulting color spectrum is due to the slight bending of the light by the diamond. The fire of the diamond is the light that shoots back through the diamond’s top after it is bounced off inside its walls to its center. A high-quality cut grade assigned by a gemologist means that the diamond exudes a high degree of fire and brilliance. A high level of brilliance will also be attained if the diamond is well-balanced and symmetrical with properly aligned facets. Polishing also affects the brilliance of a diamond, so its every facet should be polished professionally right after cutting. Diamonds that are too shallow or too deep return less light. The crown’s angles return back the most reflected light. As light hits the surface of the diamond, some enter the stone while some are reflected back. The “brilliance” of the diamond depends on good light performance, or light refraction and the return of light through the diamond’s top. BrillianceĪ diamond’s brilliance is dependent upon the quality of cut which gives the diamond the ability to reflect the most amount of light. All polished diamonds regardless of proportions or shape, for example, have the same dispersion property. Dispersion is a property inherent in transparent materials, and oftentimes a single value based on the refractive index of the materials. In dispersion, white light separates into colors that take different paths because the amount of refraction that takes place in the material differs. ![]() Scientifically, dispersion refers to the break-up of white light into a spectrum of colors. Dispersion and fireĭispersion and fire are different but related attributes of polished diamonds. Ideally, diamonds should display lots of captivating flashes visible across the surface of the gem. The light that bounces off the diamond’s internal walls is the diamond quality called scintillation. ![]() The light that enters a diamond may not immediately get reflected back and may reflect towards the diamond’s center from its inside walls. Scintillation refers to the intense sparkles of light or flashes produced when tilting a diamond from side to side. The four main qualities of the diamond that are dependent on the grade of the cut are scintillation, dispersion, brilliance, and fire. When choosing a diamond, the highest cut grade should be of prime consideration. Therefore, the cut is the most important factor in producing a diamond of excellent appearance. Poor cuts can produce diamonds that are dull and lifeless as well as appear dark, even though its clarity and color are of superior quality. When the cut is poor, the light entering the diamond may become limited or the light will seep out the sides and bottom of the gem. The high quality of the diamond cut will produce a diamond with fire, scintillation, and a dazzling brilliance due to a high light return. The proportions of a diamond cut, the polish, and the symmetry of the stone are the three main factors that give a diamond its optimal light reflection. ![]()
