The shade of red varies depending on where it is mined, and may be a deep pink-red, a reddish-orange, red with a violet cast, or even a deep wine color. The paler pink Corundum, debated as Ruby by some, is usually referred to in gemological terms as Pink Sapphire rather than Ruby. [Simmons, 332][Fernie, 139-141][Eason, 71][gemselect.com][Mindat.org]
All natural Rubies have imperfections within them, including color impurities and inclusions of Rutile needles known as “silk.” These inclusions help distinguish natural Ruby from synthetics.
Ruby emanates with a vibrancy unsurpassed in the mineral kingdom. It actively stimulates the Base Chakra, increasing life-force energy throughout the physical body and into the spirit. It promotes a clear mind, increased concentration and motivation, and brings a sense of self-confidence and determination.
Ruby initiates the sensual pleasures of life, encouraging one to enjoy being in the physical world. Ruby has always been associated with love, especially faithful passionate commitment and closeness.
Ruby is a stone that is not often used for meditation. Most have found that it is just too invigorating to be effective in a meditation ritual.
Working with Ruby one may feel that all sense of limitation has been removed, strengthening courage, joy, leadership qualities and selfless work in all spiritual endeavors.
