Ruby (Eyeball)

Ruby, nicknamed Eyeball by Steven, is a Homeworld Gem who made her debut in "Barn Mates". She and the other Ruby troops were sent to Earth by Yellow Diamond to locate Jasper.

Appearance
Her outfit consists of the regular Homeworld uniform. She has the lightest complexion among the Ruby troops. Her gemstone replaces her left eye.

Personality
She seems to be the most invested in the mission to track Jasper and is the most stoic, barely saying anything, and even anxious. She initially appears to be very intimidating, but she reveals to be quite polite when she thanks the Crystal Gems for their cooperation.

Gemology


Gemstone Information


 * Rubies are composed of a material known as corundum, the second hardest crystal structure after diamond (9,10 on the Mohs Scale of Hardness).
 * Since Ruby is a member of the corundum group, it is closely related to sapphire and thus shares some properties with it, such as hardness, composition, and double refraction.
 * In its pure form, corundum is colorless.
 * Rubies are the most expensive colored stone, going by carat.
 * The word “ruby” comes from the Latin ‘ruber’ meaning red and, like many other gemstones, the ruby’s symbolic meaning is heavily dependent on its coloring.
 * Natural Ruby is one of four “precious” gemstones (including diamond, emerald, and sapphire), known for its rarity, monetary value, and hardness (second only to diamond).
 * Natural Ruby can be distinguished from synthetic ruby by its inclusions; natural ruby typically exhibits inclusions, whereas synthetic ruby tends to be eye clean.
 * The color of ruby is its most important quality factor. The most sought after color is a strong pure red to red with a hint of blue, called pigeon's blood.
 * The vivid red color of ruby means that it is associated with desire, and it is thought by some to be a stone of love with an aphrodisiac effect.
 * When the color of ruby is too light, it is classified as pink sapphire, but the line between pinkish-red ruby and pink sapphire varies by region.
 * The ruby is closely associated with aspects such as vitality, life, passion and fire, all of which can be symbolically linked to the color red.
 * This shows in Ruby's emotional temperaments and overall emotional/angry attitude as well as her strength.
 * It is said that rubies can over-stimulate people who are sensitive or irritable.
 * Ruby is the traditional birthstone of those born in July and is also the zodiacal stone for Cancer and Aries.
 * Ruby is also used to celebrate the fifteenth and fortieth wedding anniversaries.
 * The day assigned to Ruby is Tuesday (hence the Rolling Stones song, "Ruby Tuesday").
 * The planet Mars is famously known as “the red planet”, due to the high concentration of iron oxide (basically rust) on its surface and rubies, along with all of the aspects mentioned above, have been linked with Mars in one form or another.
 * Ruby is the national gemstone of Burma and Thailand.
