Ruby is the most powerful of the red stones (which also include garnet, red jasper, and carnelian). The color red, though sometimes associated with the first chakra, is the natural partner of the second partner, which relates to sexuality, blood circulation, and flow in general, and feeling.
This is definitely not a stone for anyone who tends to be fiery in nature. This can include the fire signs Aries, Leo, and Sagittarius, or anyone who has a predominance of fire signs in their natal chart. It is probably also not for the quick-tempered, for people who are easily irritated or nervous.
Ruby is a stone which needs to be used with care because, like opal, it amplifies all emotions. This can be very valuable if you feel that you need to bring long-held anger to the surface. 
Meditate with a ruby in one hand and clear quartz in the other or place ruby and clear quartz on the pelvic area, and consciously allow the anger to arise. The clear quartz will accelerate the process of releasing and dissolving the anger.
Many people have experienced ruby as a stone which helps to relieve exhaustion and depression. Although I don't recommend that ruby or any stone be used as a replacement for medication it can be very helpful in cases of mild or temporary depression.
Ruby can also awaken passion -- not only sexual passion, but passion for living, for experiencing, for creating. It can stimulate motivating energy and the power of creative visualization. It also helps people to be realistic and honest about their goals and intentions.
Thus, if you are experiencing inertia, feel unimaginative, or feel that your imagination is creating dreams which are unrealizable; a ruby may help you to move forward in a positive way.

Surprising as it may seem, ruby and sapphire, so different in color, actually belong to the same mineral family: corundum, the mineral form of alumina which crystallizes in the hexagonal system. The red color of ruby results from a small admixture of chromic oxide. The most prized tint is blood red or crimson known in the trade as "pigeon's blood" red. The color of this corundum varies, however, according to the geographical locality of the mine. Siamese rubies, for instance, are of a deeper garnet red than those found at Mogok in Burma, while Ceylon ruby is of a pinkish dull red. Corundum is extremely hard, 9 on the Mohs scale. It is, therefore, not quite as hard as diamond as but much harder than other minerals, including emerald. Transparent ruby, when cut en cabochon, may reflect light so as to produce star-like bands, a phenomenon rated highly by the experts. If viewed from a certain direction, bands of light are reflected onto the surface of the crystal forming a six-ray star shape. This optical effect is due to the presence of fine canaliculi or inclusions of rutile. The color of these "starstones" varies from pale rose red, to deep crimson, to purple. Generally speaking, the darker the crystal, the less evident is the star, and vice versa. It is a rare gem indeed in which the color and the star are of equal beauty.
