Not every planet is in harmony with the other celestial bodies. Likewise, the vibrations of the two conflicting planets (corresponding gems) should not be mixed. The effects are nullified or result in an unbalance. A particular gemstone should not be worn with the conflicting planetary gemstones. Thus, one should understand the compatibility of the gemstones with each other.
" Sun is incompatible with Saturn, Venus, Rahu and Ketu. Hence, sun gemstones such as Ruby should not be used with Blue sapphire, Diamond, Hessonite or Cat`s Eye.
Moon is incompatible with Rahu and Ketu. Hence Moon gems such, as Pearl should not be used with Hessonite or Cat`s-Eye.
Jupiter is incompatible with Mercury and Venus. Therefore Jupiter gems such as Yellow Sapphire should not be used with Emerald or Diamond.
As Rahu (Moon`s north node) is incompatible with Sun and Moon, Rahu gems such as Hessonite should not be used with Ruby or Pearl.
Mercury is incompatible with the Moon. Mercury gems such, as Emerald should not be used with Pearl or Moonstone.
Venus is incompatible with the Sun and Moon. Likewise, Diamonds and other colorless gems should not be used with Ruby or Pearl.
Ketu (Moon`s south node) is incompatible with Sun and Moon. Cat`s eye gems should not be used with Ruby or Pearl.
As Saturn is incompatible with Sun, Moon and Mars, Saturn gems such as Blue sapphire should not be used with Ruby, Pearl or Red Coral.
Mars is incompatible with Mercury and Saturn. Therefore, Mars gems like Red Corel should not be used with Emerald or Blue Sapphires.
