Ruby

About this stone

Ruby is corundum coloured red by chromium and has been worn as a Sun stone in nearly every culture that mined it. Vedic astrology classes it as the gem of the Sun directly; Western astrology threads it through Mars as well. It is the stone for a dimmed identity — where a partner has eclipsed yours, or where solar self-expression has gone quiet under long compromise.
