Your Complete Guide to Diamond Fire

Sparkle. Brilliance. Flash. Shine. The way a diamond catches the light is beautiful and inspiring. Appropriately, there are many ways to describe that effect. In the process of selecting a diamond, we tend to talk about brilliance a lot, but the stone’s attractive sparkle is made up of more than just brilliance. One other factor is fire.

What is the fire in a diamond?

Think color, like flame. A diamond’s “fire” is the effect produced when white light disperses into rainbow colors when it hits the diamond’s facets (the angled cuts in the stone).

There are two main kinds of facets: Physical facets and virtual facets. A physical facet is an actual cut in a diamond. Those physical facets can bounce light in multiple directions, creating virtual facets. (These virtual facets are also related to diamond brilliance and scintillation.) The more virtual facets a diamond has, the more it can refract light, adding to the diamond’s fire.

(If you think of the prism on the cover of Pink Floyd’s Dark Side of the Moon, which depicts white light hitting a transparent triangle and rainbow light coming out the other end — that wasn’t the hallucination of a stoner; that’s the fire we’re talking about.)

What diamond cut has the most fire?

Round brilliant cut diamonds tend to have the most fire. That’s by design: Gemologists have been working to maximize the fire of that cut since it was created in 1919 by a PhD-educated engineer who used mathematical calculations to optimize its sparkle. The round brilliant has 58 facets — a high number of physical facets that then create even more virtual facets.

How to make sure you get a diamond with plenty of fire

To ensure you get plenty of diamond fire, select a stone with excellent symmetry. That affects how the stone can bounce and refract light, which increases those crucial virtual facets. A gemologist can help you with this.

A triple-X stone is probably your best bet. That stands for “triple excellent,” meaning excellent cut, symmetry, and polish. This is one of the grades on a diamond’s GIA certificate, which any diamond seller should review with you before you buy.
