Yes! The colour and intensity of the fire influence the opal gemstone’s metaphysical attributes. Generally, Opal is the gemstone for planet Venus. But according to the astrologers, the color of fire also influence the Opal’s astrology. The color of fire that shows dominance in the flashes is more likely to give results of the associated planet. For instance, if the red is more prominent in the fire, then the opal will also harness the energies of sun whereas if blue is the dominant color in flashes, then Saturn positive energies will also get combined. An opal displaying a full spectrum of colors in the fire is considered best from the astrological perspective.
