Diamonds shine due to a mix of three major things: reflection, refraction, and dispersion. Reflection is when light hits a diamond and the light comes back at you, this is the instant sparkle you see. However, light is not always reflected back into your eye but may pass through the diamond.
Diamonds are prismatic and have a high refractive index. This means that diamonds reflect a lot of light. Compared to a piece of a glass, the diamond’s high refraction will reflect more light making it way more sparkly. The last thing that helps a diamond sparkle is dispersion. Dispersion is when white light enters into a diamond but is reflected back to your eye as a rainbow of color. Known as “fire” in the industry, dispersion is responsible for the red, blues, greens that you see when a diamond sparkles.
Diamonds are cut to maximize the sparkle factor, but certain shapes do tend to shine more brilliant than others. The first thing to understand is the difference between shape and cut. Although the two terms are used interchangeably by some, they mean very different things. A diamond’s shape is the way the diamond looks, while cut refers to the diamond’s ability to reflect light. There are two different cuts, brilliant and step.
A brilliant cut diamond have facets that are generally triangular, great for really showing off that fire and a step cut diamond usually has facets that are straight and parallel and there are usually less of them, great for big diamonds.
Of all diamond shapes, the brilliant round cut diamond sparkles the most.. The 58 facets of the brilliant cut are mostly triangular and the perfect symmetry that results from the round shape means that when light hits the diamond, it comes right back out the top allowing for unbelievable shine. It’s one of the most popular diamond shapes, as 75% of diamonds that are sold are round.
