RUBY (Manik): of good quality is as expensive as a diamond. The stone
belongs to the Sun and so protects the wearer from sunstroke. As it is of
the colour of blood warriors wore it to battle. The ruby also endows
knowledge, intelligence and mental peace and ensures longevity. Women are
warned against wearing rubies as they may lose some of their lustre to the
stone. Those born on the 8,17,26,6,15 and 24th of the month should not wear
rubies. A stone of 3 to 5 carats set in gold worn on the ring finger gains
more power if worn when the Sun is in Aries or Leo.
