Such is the case with diamond and moissanite. ![]() The greater the dispersion in a material, the more fire you will see, and less brilliance. Some of those rainbow color beams manage to get back together as white light, and some stay separate and show up as colors.ĭispersion happens in any material, in some it’s less pronounced and in some it’s more. A diamond is a prism, and a very complex one at that, hence white light splitting but showing equal parts white and rainbow. Think of Pink Floyd’s Dark Side of the Moon album cover art.Ī prism (in this case a diamond) splits incoming white light into rainbow light, and the only way to get the white light back is to run the rainbow through a prism again, and ‘tie’ back together all the 7 colors, creating white. All of these colors brought together form white light, and if you split white light through a prism, you get the rainbow.

Different enough to get more rainbow color than white light, especially when paired with each material’s dispersion and the way the facets are arranged. Each time the light hits another facet within the diamond or moissanite, it’s reflected at that angle, so overall a diamond and a moissanite work light a little differently. When the light first enters a diamond, it does not go straight through, it goes through bent at a slight angle. ![]() The greater the index, the greater the bend and thus the trajectory of the light beams within the prism. All transparent materials have a refractive index, and diamond’s index is 2.42, while moissanite’s index is 2.69. The refractive index bends the light within a prism (diamond)Ī diamond’s refractive index is the degree to which it can bend the light when it enters the diamond. A diamond is a prism, it splits light, and we first need to look at the two most important factors that determine fire and brilliance: refractive index and dispersion. ![]() There are several factors affecting why you see more fire or more brilliance, and why some diamonds just don’t sparkle as much as others. Key factors affecting fire and brilliance in a diamond Meanwhile a diamond cut too shallow will show you mostly brilliance. A diamond cut too deep will not have much scintillation, and may show you mostly fire. A good diamond will have good scintillation, and show you equal parts brilliance and fire. Scintillation in a diamond is the interplay between fire and brilliance, the way they interact and follow one another. Most diamonds will show equal parts fire and brilliance, and this is one of the key ways to tell a diamond from a moissanite: the moissanite will have more fire than brilliance when compared to a diamond of the same size and cut. The diamond is a prism and it splits white light, and some of the light exits as fire ( rainbow) and some it exits as brilliance (white). What is fire in a diamond ?įire in a diamond is the colorful sparkles you see, the rainbow-colored sparkle that results when white light is split into its components. The white light you see coming back out of the diamond is the brilliance of the diamond.Ī very well cut diamond will give you a balanced brilliance and fire output. A diamond, when faceted and polished, acts like a prism, where white light enters, then splits into the rainbow, and then some of the light is brought back through the top (crown and table) as white light, and some of it remains rainbow-colored. 6.2 The number and size of facets affects brilliance and fire What is brilliance in a diamond ?īrilliance is the white light that a diamond sends back into your eyes. ![]()
