Zircon is a more advantageous substitute for valuable diamonds than White Opal with Fire. This is due to zircon's well-known vedic astrological similarity to diamond's astrological qualities. Zircon physically resembles the priceless and rare diamond gemstone quite a bit. White zircon is a strong, incredibly translucent gemstone with a beautiful brilliance. Opal is relatively delicate and requires very minimal additional care and attention. After white zircon, opal may be the second most popular choice for obtaining Venus' astrological advantages.
