Do real diamonds have fire?

Diamond happens to have a very high refractive index. The higher the refractive index, the greater the potential for dispersion. While diamond therefore has a very high potential to exhibit fire, the quality of the cut is the key to whether that fire potential is realized.

Do diamonds have fire?

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.

What can break a diamond?

While there may not be many naturally-occurring materials out there that are stronger than diamonds, certain man-made metals like tungsten and steel have a higher tensile strength. That means a direct hit with an ordinary hammer can absolutely break a diamond.

Do real diamonds glow?
