Ruby

Ruby

Physical Characteristics: A pink to blood red precious gemstone which derives its color from the presence of Cr⁺³ ions. Some specimens display a star shape when cut correctly, and these are highly valued. Most natural Rubies are rutilated, and most Rubies on the market have been treated in some way, most often with heat. 

In Nature: The stone's Chromium ions absorb yellow-green light, and then re-emit it as red light. This luminescence adds luster to the gem, and led to the invention of the first successful laser in 1960. 

Chemical Composition: Al2O3:Cr

Mohs Scale Hardness: 9 (very high)

Can be Found: Myanmar, Thailand, Cambodia, India, Afghanistan, Australia, Japan, Scotland, Brazil, USA, Greenland, Kenya, etc.

Healing Properties*: Its healing effects are many, but the Ruby is most associated with the cardiovascular system. It may also treat sexual dysfunction, bladder problems, or conditions of the blood. Further associated with bodily warmth, it may improve circulation in the extremities and help to manage anemia.

Magickal Properties: Actually a red variety of the same mineral which comprises Sapphire, Ruby is a stone of many uses. Many sources cite it as an invigorating stone which can be used to recharge when one is feeling drained. Scott Cunningham recommends pairing a crystal with a red candle for this purpose. 
It is also well known for its protective properties. Kings and knights would use it to embellish their breastplate, while many fairy tales pass on the knowledge that a Ruby's color will pale in color when its bearer is in danger. Similarly, it can help to ward off negative emotions and to recover a more positive outlook. Touched to the corners of the home or garden, a Ruby will guard the space from harm.
Ruby is likewise a stone of wealth and prosperity. One could be used in a money spell, or placed in a piggy bank or a wallet. It also helps insure that one's income is stable, rather than constantly fluctuating. For those who collect gems, Indian lore suggests that the bearer of a Ruby can use it to draw more precious gems to themselves.
The crystal is further noted for its ability to inspire feelings of joy or bliss. Wearing a stone set in jewelry is a convenient way to experience this effect.

*Magickal healing should never take the place of seeing a doctor and following any recommended prescriptions, actions, or other advice. Magick works best in tandem with physical efforts, anyway, so don't skimp on those check-ups!
