In diamond appearance, what does 'fire' refer to?

Explanation:
Fire describes the dispersion of white light into spectral colors as it travels through and exits a diamond. Diamonds bend different wavelengths by different amounts, so the light separates into colors like red, orange, yellow, green, blue, and violet, creating those colorful flashes you see. This is about color separation, not just brightness. Scintillation, by contrast, is the bright sparkle from reflections and refractions that changes with movement, not the appearance of colored flashes. Inclusions or cracks don’t produce the characteristic spectrum of colors associated with fire.
