No, sapphire does not have "fire" in the gemological sense.
Sapphire, while possessing brilliance, lacks the characteristic "fire" seen in diamonds. "Fire," in gemology, refers to the dispersion of white light into spectral colors. Diamonds excel at this due to their high refractive index and dispersion, creating the flashes of color. Sapphires, while beautiful, don't disperse light in the same dramatic way. Although white sapphires exhibit brilliance, it is not as intense, and they do not create "fire" like diamonds.
In simpler terms, when jewelers talk about a gemstone having "fire," they mean how much it breaks up white light into rainbow colors. Sapphires are known for their color and brilliance but not specifically for this "fire" effect. This difference is due to the physical properties of the stones.
